Quebec Trip Permits

If you have a heavy vehicle registered in another Canadian province or territory or in the United States, and you’re using it for transportation in Québec, you need a trip permit. This permit is valid for 10 days and allows your vehicle to travel through or within Québec. However, if your vehicle is registered under the International Registration Plan (IRP permits) and Québec fees are paid, a trip permit is not necessary.

Quebec Fuel Permits

If you’re subject to IFTA but lack an IFTA license, you’ll need a certificate for occasional trips from your base jurisdiction and every other member jurisdiction you travel in. This certificate must be obtained before each trip and kept in your vehicle. 

The certificate allows travel in the issuing member jurisdiction without fulfilling IFTA obligations such as quarterly fuel tax returns. Keep the certificate in your qualified motor vehicle.

For temporary registration, a temporary 1-month certificate can be issued by the SAAQ or a dealer to allow operation on Québec roads for a limited period, applicable even for vehicles not connected to the Québec road network.

Quebec Specialty Permits

The need for special permits may arise from your load’s nature, size, and weight. 

Mobile Home and Modular Home Permits:

There is no official information referring to mobile home or manufactured house permits.

Amber Light Permits:

Vehicles escorting oversize loads shall be equipped with amber warning lights. 

Loading Zone Permits:

A loading zone permit may be issued for using commercial loading zones by non-commercial delivery vehicles. 

Special Permits:


The Ministry of Transportation imposes restrictions on vehicle loads and dimensions to safeguard infrastructure integrity and prioritize the safety of all road users.

Under the Highway Safety Code, vehicles adhering to authorized load and size specifications outlined in the Vehicle Load and Size Limits Regulation can freely traverse Québec’s road network.

In cases where a vehicle or combination thereof cannot meet Regulation requirements, acquiring a special permit offers a potential solution.
