Oversize/overweight permits

Carriers must apply for permits to operate or transport oversized or overweight vehicles and loads. Carriers are responsible for following all permit conditions to ensure their vehicles operate safely on Ontario's King's highways.

Who needs a permit

You will need an oversize/overweight permit if the dimensions or weight of your vehicle and/or load exceed the limits set out in the Highway Traffic Act.

Permits are issued for oversize vehicles or loads if they cannot be reduced in size or would:

  • be unable to perform the function for which they were intended
  • be unusable for their intended purposes
  • require more than eight work hours to dismantle using appropriate resources and equipment

Limitations

Overheight:

  • the load must not be made up of articles loaded or mounted on top of each other in a way that will create additional height

Overwidth:

  • the load must not be made up of articles loaded or mounted side by side or crosswise in a way that will create additional width

Overlength:

  • the load must not be made up of articles loaded or mounted one behind the other in a way that will create additional length
  • any overhang to the rear must not exceed 4.65 m from the centre of the rearmost axle

Overweight:

  • the load must not be made up of more than one article
  • when crossing bridges, vehicles over 45,000 kg gross weight must be operated at the lowest practicable speed
  • bridge postings and load restrictions pursuant to Part VII of the HTA apply

Types of permits

There are four types of oversize/overweight permits. Each permit has specific conditions that must be strictly adhered to.

1. Annual permits

Annual permits are used for repeat trips with oversize/overweight vehicle and/or loads to maximum weights and dimensions as follows (subject to vehicle configuration):

  • Weight : 63,500 kg
  • Width : 3.85 metres on multi-lane highways, 3.7 metres on 2-lane highways
  • Length : 25 metres
  • Height : 4.26 metres

They are valid for 12 months from the date of issue on all King's highways.

Carriers with annual permits can travel on Highway 407 ETR as long as the vehicle has a valid transponder.

When to apply

Annual permits take 10 to 15 business days to be issued from the date the application is received. To avoid delays, apply at least 30 days before the requested start date.

2. Project permits

Project permits are issued to allow carriers operating under the terms of a contract, to move similar loads, objects and structures over the same specified route for a period up to and including six months, depending on the duration of the contract. Maximum weights and dimensions as follows (subject to vehicle configuration):

  • Weight : 70,000 kg
  • Width : 4.3 metres (subject to clearance check)
  • Length : 36.75 metres
  • Height : subject to clearance check

The weights and dimensions provided must be specific to the load. The weights and dimensions specified on the permit are those of the load,not the maximum limit.

When to apply

Include a copy of the contract with your application. The letter of contract must be written on company letterhead and include:

  • the name and address of the carrier
  • the contract number (if available)
  • the duration of the contract
  • a description of the product being transported
  • the origin and destination of the load, specifying the complete route (including municipal roads)

Once the ministry receives all the required documents, staff will assess traffic and construction concerns before it approves and issues the permit.

3. Single trip permits

A single trip permit is issued for a one-way trip along a specified route for a limited period.

When to apply

A carrier must apply a minimum of 3 business days prior to the proposed move date to allow the Permit Issuing Office sufficient time to process the permit request.

Superloads

Superloads exceed any of the following limits:

  • 120,000 kg gross vehicle weight
  • 5 metres in width
  • 45.75 metres in length

Permit applications for Superloads of 6 metres or greater must include justification that demonstrates the necessity of transporting the loads on the province's highways, and require extra time and documentation. These loads will be subject to a thorough review by the ministry's Weight and Load Engineer, as well as various senior ministry management personnel.

Those considering Superload moves should consult with the Permit Issuing Office in the early planning stages. A carrier must submit their application a minimum of 5 days prior to the proposed move date due to the more involved approval process. Complex operations may take as many as 6 months to fulfill all requirements.

For gross vehicle weights exceeding 120,000 kg, carriers will need to submit an evaluation by a qualified engineer to evaluate the bridges on their route for ministry approval.

Approved bridge consulting engineers with design and evaluation qualifications

4. Special vehicle configuration permits

Special vehicle configuration permits are issued for vehicles with unique weights or dimensions that vary from the HTA and other regulation. They are subject to economic, infrastructure and safety assessments by the applicant, to prescribed ministry standards.

The purpose of these permits is to:

  • harmonize configurations, weights and dimensions with those of any other jurisdiction
  • allow for a trial of a vehicle
  • allow for a variance from a limit within a specific geographical area

When to apply

Applications for these permits may take up to 14 days to process. To learn more, contact the ministry at:

  • 416-246-7166 ext. 6306
  • 1-800-387-7736 ext. 6306 (Ontario only)

Applying for a permit

Applications can be printed, filled out and sent to the Ministry of Transportation by fax to 905-704-2545, by mail or in person.

Before you obtain a permit, there may be other requirements you need to meet to travel in Ontario (e.g. CVOR, National Safety code, etc.). The operator is responsible for complying with registration, fuel tax and other federal and provincial requirements and procedures.

The ministry must review and approve all documentation before it issues a permit. Consideration will only be given to the move if you can adequately prove that it is absolutely necessary.
