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:
- annual permits
- project permits
- single trip permits
- special vehicle configuration permits
You can apply and pay for an oversize/overweight permit online, by mail or fax.
Completed oversize/overweight permit applications that include credit card payment information will not be accepted by e-mail.

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:
- operate at the lowest practical speed when crossing bridges if your vehicle is more than 45,000 kg gross weight
- continue to follow all posted bridge and/or load restriction signs and restrictions as described in the Highway Traffic Act

The single-trip permit fees depends on the size and weight of your vehicle and load combination and the length of your trip.
The proposed travel route on the permit will be verified to ensure that all provincial highways and municipal roads listed are correct and that construction activities will not impact the travel route including, width, height, length or weight restrictions. If you are unable to clear all the structures and/or construction restrictions along the proposed route, you will have to provide a feasible alternate route. It is your responsibility to plan and provide the most feasible, complete and continuous direct route.

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 Oversize/Overweight Permit Issuing Office as early as possible.
Requirements for superload permits include:

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
