Overview

You will need an oversize/overweight permit if the dimensions or weight of your vehicle and load combined exceed the limits set out in the Highway Traffic Act. Oversize/overweight permits are valid for Ontario’s King’s highways only. If you want to drive on municipal roads, you may be required to get additional permits or permission directly from that municipality.

You are eligible to apply for a permit if your vehicle or load cannot be reduced because it:

  • could not be used for its intended purpose or function
  • would require more than eight work hours to dismantle using appropriate resources and equipment

There are four main types of oversize/overweight permits in Ontario, with different fees and specific conditions that you must follow to ensure your vehicle can operate safely:

  1. annual permits
  2. project permits
  3. single trip permits
  4. special vehicle configuration permits

You can apply and pay for an oversize/overweight permit online, by mail or fax.

Restrictions

You will not be eligible for a permit if your:

  • vehicle, load or combination will be overweight and your load is made up of more than one item
  • vehicle or load is overheight, overwidth or overlength because of the way you have loaded it. For example, items stacked in a way that creates unnecessary additional height, width or length.
  • vehicle or load is overlength, your load is made up of more than one item and the overhang of your load to the rear exceeds 4.65 metres from the centre of the rear-most axle

Once you have a permit you must:

  • continue to follow all posted bridge and/or load restriction signs and restrictions as described in the Highway Traffic Act

When you apply for a project permit, you must include a copy of the contract you are working on, written on the hiring company letterhead. The project documents must include:

  • the name and address of the carrier

Single trip permits

Single trip permits are for one-way trips along a specified route. They are valid for up to 7 days.  

You should apply for single trip permit at least 5 days before your trip date to allow time for processing. Your permit may only be issued to you 3 business days before your start date.

The single-trip permit fees depends on the size and weight of your vehicle and load combination and the length of your trip.

Superloads

A “superload” is a vehicle and/or load that exceeds any of these limits:

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

Getting a superload permit requires more steps and can take longer than other oversize/overweight permits (at least 5 business days and up to 6 months in some cases). These applications will be reviewed by weight and load engineers within the Ministry of Transportation as well as other ministry departments.

If you are considering applying for a superload permit, contact the Ministry of Transportation’s Permit Issuing Office as early as possible.

Requirements for superload permits include:

  • having valid Certified Superload Escorts to accompany the move
  • submitting a traffic management plan
  • applications with a width of 6 metres or more and/or a gross weight more than 120,000 kg must include project justification documentation that demonstrates the need for transporting the loads on highways
  • for gross vehicle weights exceeding 120,000 kg, you must have the bridges along your route evaluated by a qualified engineer and the report must be submitted to the Ministry of Transportation Permit Issuing Office for approval

Special vehicle configuration permits

Special vehicle configuration permits are for vehicle and load combinations with unique configurations, weights or dimensions that differ from those in the Highway Traffic Act. They can be used:

  • for trials and pilot projects
  • by request from other jurisdictions to allow something that is permitted in those locations
  • for vehicle combinations that need exemptions or need specific configurations, weights or dimensions for travel within specific municipal or other local regions
  • to provide temporary accommodation when the Highway Traffic Act and regulations are updated

You may be required to provide safety, economic or infrastructure assessments to support your application.

Special vehicle configuration permits can take 15 business days or more to process and the costs vary. To learn more, contact the Ministry of Transportation.
