Wide Load Permit Ontario: Oversize and Overweight Regulations

Last Updated: July 2026
Last Reviewed: July 2026

Reviewed By: Vectra Heavy Haulers Permit & Compliance Team

A wide load permit Ontario issues authorizes a nondivisible vehicle or load that exceeds legal size or weight to travel on approved provincial highways under stated conditions. Ontario’s permit environment combines metric dimensions, axle and configuration rules, PRIO online applications, route-specific approval, private-escort requirements, municipal permits, border crossings, seasonal weather and major urban restrictions. The permit is therefore one part of a complete compliance package, not permission to use every road between pickup and delivery.

Ontario is Canada’s largest freight market and a central link between Quebec, Manitoba, the Great Lakes, the U.S. Midwest and the Northeast. Heavy-haul projects serve automotive and advanced manufacturing, mining, steel, nuclear and hydroelectric power, construction, wind energy, agriculture, forestry, ports, rail terminals and cross-border supply chains. Toronto congestion, municipal roads, northern distances, bridge clearances, winter conditions and international crossings make route continuity essential.

At Vectra Heavy Haulers, we help carriers, project managers, freight brokers, manufacturers, utilities and contractors obtain Ontario wide-load permits, coordinate escorts, review routes, manage multi-jurisdiction requirements and plan complex heavy-haul transportation across Ontario and neighbouring provinces or states.

Important compliance note: Requirements are route-specific. The current issued permit, official agency instructions, road-authority restrictions and law-enforcement directions control the movement. Provincial permits may not authorize municipal, county, port, bridge, ferry, private, First Nations, utility or border-facility roads. Verify every jurisdiction before dispatch.

Ontario Permit Quick Answer

An Ontario oversize permit is generally required when a nondivisible vehicle and load exceed the legal dimensions or weight in the Highway Traffic Act and applicable regulations. MTO permits cover King’s highways only. Municipal roads, bridges, ports and private facilities may require separate approval. PRIO supports annual and single-trip products, while project permits, special vehicle configurations and some complex applications require direct review.

Vectra Insight: The Permit Is Only One Layer
For Ontario heavy haul, approval depends on the combined permit, route, axle plan, escorts, infrastructure, weather and local access. The last kilometres often require more coordination than the main highway corridor.

Ontario Legal Size and Weight Limits

Before applying for an Ontario wide-load permit, determine whether the loaded vehicle exceeds any legal dimension, axle limit, axle-group limit, gross-weight limit, overhang rule or configuration standard. Canadian legal limits are expressed in metric units and vary by configuration. The table provides planning benchmarks, not a substitute for the current regulation.

Category	Common legal benchmark	Important qualification
Overall width	2.60 m (8 ft 6 in)	Wider vehicles or loads generally require an Ontario oversize permit.
Overall height	4.15 m (13 ft 7 in)	The carrier remains responsible for actual overhead clearance.
Common tractor-semitrailer combination length	23.0 m (75 ft 6 in)	Configuration, trailer wheelbase, kingpin and overhang rules also apply.
Semi-trailer length	Commonly 16.2 m under SPIF configurations	Legacy, special and commodity configurations must be checked separately.
Legal axle/group weights	Configuration, tire and spacing dependent	Ontario SPIF rules make axle arrangement and load equalization critical.
Gross vehicle weight	Calculated by configuration and axle rules	A single universal GVW number is not adequate for all Ontario combinations.
Rear overhang	Configuration-specific; permit review becomes more restrictive above 4.65 m	Long rear projections can trigger single-trip and escort requirements.

Official basis: Ontario Ministry of Transportation (MTO) vehicle weight and dimension rules. Verify the exact configuration before movement.

Permittable Limits and Special-Review Thresholds in Ontario

A permit authorizes an exception; it does not create a universal maximum. Routine systems can process loads inside defined envelopes, while exceptional width, height, length, overhang, weight or configuration can trigger manual review, route surveys, bridge analysis, traffic-control plans, utility coordination or police involvement. Ontario may approve different limits on two routes for the same load because infrastructure and traffic exposure differ.

Permit category	Primary purpose	Planning significance
Single-trip oversize permit	One route and movement	General nondivisible wide, high, long or overhanging loads.
Single-trip overweight permit	One route and movement	Loads exceeding legal axle, group or gross limits.
Single Trip - General Loads / Annual Dimensions	Trip within pre-established annual envelope	PRIO lists up to 78,000 kg, 3.85 m on multi-lane roads, 3.70 m on two-lane roads, 32 m long and 4.26 m high for qualifying combinations.
Annual general-load permit	Repeated qualifying dimensional movements	Requires a CVOR or NSC-linked PRIO account and does not cover every road or weight.
Enhanced annual permit	Larger eligible envelope or emergency program	Additional conditions and review may apply.
Project permit	Repeated project movements	Paper/direct-office application and supporting route information may be required.
Special Vehicle Configuration / VCE	Nonstandard or overweight configuration	Engineering and vehicle-configuration approval may be required.
Municipal permit	Local road authority	Separate from MTO authority over King’s highways.

Permit categories summarized from official Ontario Ministry of Transportation (MTO) resources.

Vectra Insight: Weight Distribution Can Matter More Than Gross Weight
Bridge and pavement effects are created by axle loads, group spacing and the distance between groups. A lighter convoy with concentrated axles can be harder to approve than a heavier convoy spread over a properly engineered platform trailer.

Wide Load Permit Ontario Requirements

An Ontario wide-load permit application is normally required before movement when the vehicle or indivisible load exceeds a legal limit or needs an exception to a route, bridge, seasonal, or configuration restriction. Common triggers include:

Loaded width exceeds the legal width for the vehicle or route.
Loaded height exceeds the legal height or requires active clearance management.
Overall length, vehicle length, trailer length, wheelbase, kingpin setting or overhang exceeds the legal allowance.
Any axle, tandem, tridem, axle group, tire or gross vehicle weight exceeds the applicable legal value.
The vehicle configuration is not recognized as a standard legal combination.
The route includes a posted bridge, seasonally restricted road, mountain or remote corridor, urban restriction or other special condition.
The movement uses a crane, drilling rig, self-propelled machine, modular building, transformer, industrial vessel or other commodity with a specific permit category.
A recurring operation requires an annual, general, multi-trip or project permit rather than repeated single-trip applications.

Common Freight Requiring Permits in Ontario

Sector	Typical permitted freight
Automotive and advanced manufacturing	presses, stamping equipment, robotics, molds, production cells and plant machinery moving through Windsor, Oshawa, Oakville, Cambridge and the Greater Toronto–Hamilton Area
Mining and Northern Ontario resources	haul trucks, crushers, mills, drills, transformers and modular plants serving Sudbury, Timmins, Red Lake and remote districts
Steel, ports and heavy industry	coils, mill equipment, furnaces, vessels and project cargo around Hamilton, Sault Ste. Marie, Nanticoke and Great Lakes terminals
Nuclear, hydro and grid infrastructure	reactor support equipment, generators, transformers, turbines, wind components and transmission hardware
Construction and urban infrastructure	cranes, excavators, bridge girders, tunnel equipment, precast sections and transit-project cargo
Agriculture, forestry and machinery	combines, planters, forestry processors, mill equipment and rural utility loads

Many loads require a wide-load permit in Ontario because of weight before they appear visually extreme. Presses, transformers, generators, mining components and industrial vessels can fit within ordinary width and height while creating axle and bridge concerns. Agricultural, modular and wind-energy freight often creates the opposite problem: manageable weight but extreme width, height or length.

How to Apply for Ontario Wide-Load Permits Online

The principal system is PRIO (Permitting & Registration for International Registration Plan & Oversize/Overweight). Carriers should use the current official portal and account structure rather than relying on an old bookmark or a commercial application page. Permit products available online and the amount of automated routing vary by permit type.

The oversize overweight permits Ontario carriers use include single-trip, annual, enhanced annual, project and special-configuration products. The correct product depends on the actual load and route.

PRIO (Permitting & Registration for International Registration Plan & Oversize/Overweight) Application Workflow

Create or verify the carrier, permit-service or authorized-representative account and connect the required safety, registration or operator identifiers.
Select the correct permit category, duration and commodity. Do not choose an annual or multi-trip product merely because it is cheaper if the load falls outside its envelope.
Enter measured loaded width, height, overall length, front/rear overhang and total weight.
Enter each axle and axle-group weight, centre-to-centre spacing, tire information and the complete truck/trailer/jeep/booster/dolly configuration.
Provide a precise origin, destination and continuous route. Identify all municipal, private, bridge, border, port, resource-road and final-mile segments.
Upload drawings, surveys, engineering documents, certificates, route letters or vehicle-configuration information when requested.
Review the draft and conditions before payment. Correct errors before issuance because some auto-issued products cannot be amended.
Download the complete permit, route and attachments; confirm current construction, restrictions and weather immediately before movement.

Information Normally Required

Carrier legal name, business address, safety/operator number, vehicle registration and contact information.
Power-unit and trailer licence plates, unit numbers, make, model and configuration.
Commodity description, divisibility status and loaded dimensions.
Gross weight, individual axle weights, axle-group weights, tire ratings and axle spacings.
Origin, destination, requested dates, continuous highway sequence and border/port/municipal segments.
Escort plan, route survey, utility contacts, police coordination and engineering support when applicable.

Common Online Application Errors

Common errors include estimated dimensions, axle spacing measured from tire edges instead of axle centres, a missing jeep or booster, selecting the wrong permit class, entering a highway-only origin when the load actually starts on a municipal street, omitting the return route, and paying before reviewing the draft. These mistakes can change fees, route, escorts or legal authority and may require a new permit.

Ontario Escort Requirements

Escort requirements are not based on width alone. Height, length, overhang, roadway type, divided versus undivided highway, traffic exposure, bridge conditions, visibility, municipal policy and the issued permit can change the count and position. The following table is a planning summary; the permit controls.

Load/route condition	Typical escort response	Planning note
Width up to permit envelope	Permit-specific	Some movements may operate without an escort when all permit conditions are met.
Width approaching/exceeding about 3.70-3.85 m	Private escort commonly required depending on road type	Annual and single-trip conditions must be checked.
Very wide load, opposing-lane encroachment or traffic control	Front and rear escorts / police as directed	Municipal police or MTO may impose additional support.
Height requiring active clearance verification	Front height-pole escort	Route survey, utility contacts and railway/bridge checks may be required.
Rear overhang greater than 4.65 m	Single-trip permit and private escort warning provisions	Exact placement and conditions appear on the permit.
Superload or complex urban route	Project-specific escort plan	Police, traffic control, utility and municipal coordination may be necessary.

Use the current Ontario Ministry of Transportation (MTO) permit and escort guidance for final requirements.

Escort Placement, Equipment and Communication

Escort vehicles should have the required warning sign, amber lighting, flags, safety equipment and reliable two-way communication. Drivers should agree on call signs, lane-change protocol, emergency stops, bridge instructions, overhead-clearance calls and lost-communication procedures. An escort should not be treated as a substitute for a route survey or professional traffic control where those are required.

Escort Cost Planning

Service	Planning range	What changes the price
Standard escort vehicle	CAD $2.00-$2.75 per kilometre	Distance, minimum call-out, urban delay and overnight travel affect cost.
Height-pole escort	CAD $2.25-$3.00 per kilometre	Usually priced above a standard pilot car because of equipment and clearance responsibility.
Minimum daily charge	CAD $550-$750	A minimum can apply even when the permitted distance is short.
Layover / standby	CAD $175-$300 per day	Weather, agency holds, site readiness and utility delays can create standby time.
Route survey	CAD $350-$900+	Complex municipal, mountain, bridge, port or utility routes may cost more.
Police / utility support	Project-specific	These services are separate from ordinary escort pricing and may require deposits or minimums.

These are Vectra planning estimates, not government fees or guaranteed quotations. Canadian escort pricing is affected by remote travel, deadhead distance, minimum hours, urban waiting, border timing, accommodation, fuel, winter conditions, police scheduling and whether the escort provider must supply specialized height equipment.

Types of Ontario Oversize and Overweight Permits

Permit type	Best used for	Key limitation
Single-trip oversize permit	One route and movement	General nondivisible wide, high, long or overhanging loads.
Single-trip overweight permit	One route and movement	Loads exceeding legal axle, group or gross limits.
Single Trip - General Loads / Annual Dimensions	Trip within pre-established annual envelope	PRIO lists up to 78,000 kg, 3.85 m on multi-lane roads, 3.70 m on two-lane roads, 32 m long and 4.26 m high for qualifying combinations.
Annual general-load permit	Repeated qualifying dimensional movements	Requires a CVOR or NSC-linked PRIO account and does not cover every road or weight.
Enhanced annual permit	Larger eligible envelope or emergency program	Additional conditions and review may apply.
Project permit	Repeated project movements	Paper/direct-office application and supporting route information may be required.
Special Vehicle Configuration / VCE	Nonstandard or overweight configuration	Engineering and vehicle-configuration approval may be required.

Ontario Permit Fees and Cost Planning

The government permit fee is usually a small part of a complex movement. A realistic budget also considers permit-service work, route surveys, escorts, police, utility crews, engineering, bridge monitoring, traffic control, ferry or toll facilities, layovers and schedule risk.

Cost item	Official/planning amount	Important note
Single-trip oversize-only permit	CAD $66.25	Current Ontario public fee listing; verify in PRIO before purchase.
Single-trip overweight permit	Weight and distance based	Cost changes with gross weight, route distance and permit category.
Annual permit	Permit-product dependent	General loads, farm equipment, prefabricated buildings and enhanced annual products are separate.
Project / special configuration review	Application-specific	May require engineering documents, VCE approval or direct office processing.
Municipal permit	Municipality-specific	Toronto, Hamilton, Ottawa and other road authorities set separate fees and procedures.
Escorts, police, utilities and engineering	Project-specific	These are not included in the provincial permit fee.

Fees can be indexed or changed. The official portal and issued invoice control.

Vectra Insight: A Low Permit Fee Does Not Mean a Low-Cost Move
An oversize-only permit may be inexpensive, while one municipal detour, utility conflict or bridge analysis can add thousands of dollars. Budget the route and operational requirements, not only the permit transaction.

Ontario Oversize Regulations and Operating Provisions

The regulatory package behind wide-load permits in Ontario includes vehicle dimensions and weights, permit regulations, highway traffic law, permit conditions, cargo securement, commercial vehicle safety rules and road-authority restrictions. The driver and permit holder must read the complete permit, including coded conditions and attachments.

Required Signs, Flags, Lights and Documents

Carry the complete permit and attachments; display prescribed oversize-load signs, flags and amber lights; maintain reliable radio communication; and secure the commodity under federal and provincial standards. The exact equipment and visibility requirements are controlled by the regulation and issued permit.

Lane Use, Speed and Bridge Instructions

A permit may require reduced speed, centre-lane or centre-of-bridge travel, one-at-a-time bridge crossing, spacing from other vehicles, no braking or gear changes on a structure, temporary traffic interruption, or an escort with an arrow board. These directions protect specific infrastructure and are mandatory even when normal traffic would use another lane.

Route and Infrastructure Restrictions in Ontario

Route issue	Why it matters	Recommended control
Posted or condition-rated bridge	Axle loads and spacing may exceed structural capacity	Bridge analysis, alternate route or exact crossing instructions.
Low bridge, sign or utility	Legal height can still exceed physical clearance	Measured route survey and utility/road-authority coordination.
Construction zone	Reduced lanes, shifted traffic and temporary barriers reduce width	Check current notices and confirm with the road authority near movement date.
Railway crossing	Long/low trailers can high-centre or foul track clearance	Profile survey, railway contact and contingency plan.
Municipal street	Provincial permit may not apply	Separate municipal permit, police window and traffic-control plan.
Remote/resource road	Limited shoulders, services and recovery capacity	Fuel, communications, recovery and weather plan.
Final site entrance	Gate width, turning radius, slope and ground bearing can fail	Site survey and engineered access plan before loading.

Vectra Insight: The First and Last Mile Matter Most
Interstates and major provincial highways are designed for freight. A plant driveway, village street or private bridge may be the controlling restriction. Route review should begin at the loading point and end at the exact unloading pad.

Ontario Travel Restrictions

Travel windows vary by dimensions, route, season, municipality, daylight, traffic, weather and permit conditions. Wide or long loads can be restricted during commuter periods, Sundays or holidays; overweight-only movements may have different hours. Never assume the schedule from a previous province applies.

Planning factor	Potential restriction	Dispatch action
Daylight / night	Dimension- or route-dependent limits and additional escorts	Use permit-defined sunrise/sunset rules and confirm night eligibility.
Weekends / holidays	Prohibitions or narrower dimension envelope	Review the current holiday schedule and long-weekend notices.
Urban peak periods	Metro or municipal curfews	Coordinate city permit and police windows.
Wind	Tall, wide and long loads may be unsafe	Set operational wind limits and monitor forecasts.
Snow, ice, fog or heavy rain	Movement may be prohibited or imprudent	Hold the load and document the decision.
Spring thaw / road bans	Reduced axle allowances and route closures	Check provincial and municipal seasonal notices.
Emergency / wildfire / flood	Road authority can suspend permitted travel	Use 511 and emergency-agency information before and during movement.

Major Ontario Heavy-Haul Corridors

Corridor	Heavy-haul planning focus
Highway 401 Windsor–Toronto–Quebec corridor	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Highway 400 / 69 to Northern Ontario	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Highway 11 and 17 Trans-Canada routes	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Highway 402 to the Blue Water Bridge	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Highway 403 / QEW and Niagara crossings	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Highway 417 Ottawa–Quebec corridor	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.
Ports of Hamilton, Toronto, Thunder Bay and Windsor	Bridge and clearance review, construction, traffic windows, municipal connections and final-mile continuity.

A named freight corridor is not automatically approved for every load. The issued route and current restrictions control, and the pickup and delivery connections can be more restrictive than the main highway.

Industries Driving Oversize Freight in Ontario

Automotive and advanced manufacturing

Ontario regularly moves presses, stamping equipment, robotics, molds, production cells and plant machinery moving through Windsor, Oshawa, Oakville, Cambridge and the Greater Toronto–Hamilton Area. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Mining and Northern Ontario resources

Ontario regularly moves haul trucks, crushers, mills, drills, transformers and modular plants serving Sudbury, Timmins, Red Lake and remote districts. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Steel, ports and heavy industry

Ontario regularly moves coils, mill equipment, furnaces, vessels and project cargo around Hamilton, Sault Ste. Marie, Nanticoke and Great Lakes terminals. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Nuclear, hydro and grid infrastructure

Ontario regularly moves reactor support equipment, generators, transformers, turbines, wind components and transmission hardware. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Construction and urban infrastructure

Ontario regularly moves cranes, excavators, bridge girders, tunnel equipment, precast sections and transit-project cargo. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Agriculture, forestry and machinery

Ontario regularly moves combines, planters, forestry processors, mill equipment and rural utility loads. These projects commonly require exact rigging dimensions, specialized trailers, axle engineering, route surveys, escorts and delivery appointments. Trailer choice, cribbing and securement can change the final permit dimensions and route.

Ontario Superload Planning

A superload is best treated as a temporary infrastructure project. The permit office may need an engineered axle drawing, route survey, bridge analysis, turning simulation, traffic-control plan, utility plan, police schedule, railway coordination, site study and proof that the selected configuration minimizes infrastructure effects.

Typical Superload Documentation

Scaled vehicle and load drawing showing every axle, spacing, tire, jeep, dolly and booster.
Certified or verified axle weights and total loaded mass.
Commodity drawing with centre of gravity, support points and securement method.
Continuous route with bridge, clearance, intersection, railway and construction notes.
Route survey photographs and measured vertical/lateral clearances.
Bridge or pavement engineering analysis where requested.
Escort, police, utility, traffic-control, staging and emergency-response plans.
Municipal, port, border, private-road and delivery-site approvals.

Common Carrier Mistakes With Wide Load Permit Ontario

Mistake	Why it causes a problem	Better practice
Using estimated dimensions	A few centimetres can change route or escorts	Measure the loaded configuration after dunnage and securement are designed.
Incorrect axle spacing	Bridge analysis and permit weight become invalid	Measure centre-to-centre and verify the axle drawing.
Assuming gross approval covers every axle	One axle or group may still be overloaded	Check individual, group, tire and gross limits.
Ignoring municipal roads	Provincial authority may end at city limits	Obtain every local permit before dispatch.
Ordering escorts after permit issuance	Suitable certified providers may be unavailable	Pre-plan vendor capacity while the permit is under review.
Treating 511 as the permit route	511 reports conditions, not legal authorization	Use both the issued route and current road information.
Dispatching on an old annual permit	Routes, conditions and validity can change	Verify the exact permit, expiry and current attachments.
Assuming neighbouring rules are identical	Each jurisdiction uses different thresholds	Build the trip as one multi-jurisdiction compliance plan.

Real-World Heavy-Haul Scenarios in Ontario

Automotive press to a GTA plant

The project must coordinate PRIO, municipal permits, bridge/overhead clearance, police windows, plant shutdown timing and rigging access. The shipment should not be released until the measured configuration, axle plan, route, local approvals, escorts and unloading access agree with the issued permit.

Mining mill component to Northern Ontario

The route may span hundreds of kilometres with limited services, winter exposure, bridge restrictions and local access roads. The shipment should not be released until the measured configuration, axle plan, route, local approvals, escorts and unloading access agree with the issued permit.

Transformer through the Highway 401 corridor

Axle spacing, bridge review, Greater Toronto timing, municipal segments and utility conflicts can be more important than the provincial application fee. The shipment should not be released until the measured configuration, axle plan, route, local approvals, escorts and unloading access agree with the issued permit.

Wind-turbine blade across rural Ontario

Extreme length, turning radius, rail crossings, local permits and front/rear escorts drive route choice. The shipment should not be released until the measured configuration, axle plan, route, local approvals, escorts and unloading access agree with the issued permit.

Cross-border machinery through Windsor

MTO authority, bridge operator permission, customs timing, U.S. permits and receiving-site appointments must function as one schedule. The shipment should not be released until the measured configuration, axle plan, route, local approvals, escorts and unloading access agree with the issued permit.

How Ontario Compares With Nearby Jurisdictions

Cross-border and interprovincial routes should be planned as one operation, but each permit must be treated independently. Similar legal width does not mean the escort, annual permit, axle-weight, travel-time or local-road rules are the same.

Jurisdiction	System / authority	Main planning difference
Quebec	GPM and Classes 1-7	Quebec permit classes, thaw zones and escort rules differ materially.
Manitoba	Provincial online permits	Prairie seasonal weights and route envelopes must be reviewed separately.
Michigan / New York / Minnesota	Separate U.S. state permits	Bridge authorities, customs and U.S. escort rules add layers.
Municipal Ontario roads	Local permits	An MTO permit does not automatically authorize Toronto, Hamilton, Ottawa or another municipal network.

Why Ontario Is Different

Ontario combines a distinctive permit system, geography, industries and freight network. The key planning differences are not captured by a single width or weight threshold. They arise from the interaction of provincial authority, municipal roads, bridges, seasonal conditions, industrial origins, remote destinations, urban traffic and neighbouring jurisdictions.

The primary online environment is PRIO (Permitting & Registration for International Registration Plan & Oversize/Overweight). Metric configuration rules, local-road authority, seasonal conditions, industrial origins and final-mile geometry make province-specific planning essential.

Frequently Asked Questions About Wide Load Permit Ontario

What is a wide load permit Ontario issues?

It is an MTO authorization for a nondivisible vehicle or load exceeding Ontario’s legal width, height, length, overhang or weight to travel on an approved King’s highway route under stated conditions.

When do I need an Ontario oversize permit?

A permit is generally required when the combined vehicle and nondivisible load exceed legal dimensions or the legal axle, group or gross weight for the configuration. The carrier should test every dimension and axle, not just overall width and gross weight.

How do I apply for Ontario oversize permits?

Many annual and single-trip products are applied for through PRIO. The applicant enters account, carrier, vehicle, load, axle, origin, destination and continuous route information, reviews the draft, pays online and receives the permit electronically. Some project and special products require direct submission.

Pre-Movement Compliance Checklist

Confirm commodity, divisibility, loaded dimensions and centre of gravity.
Verify axle weights, group weights, spacing, tire ratings and total mass.
Confirm the exact power unit, trailer, jeep, dolly and booster listed on the permit.
Read the permit, route, coded conditions and attachments line by line.
Secure every municipal, port, private-road, bridge, border and utility approval.
Confirm escorts, police, traffic control, weather, road bans and construction.
Verify site access, turning radius, ground bearing and unloading readiness.
Provide the complete permit package and do not move if the actual configuration differs.
