Studded winter tires are permitted in Northern Ontario from September 1st to May 31st for residents of specific districts, including Algoma, Cochrane, Kenora, Manitoulin, Nipissing, Parry Sound, Rainy River, Sudbury, Thunder Bay, and Temiskaming. Residents, business owners, or those with road authority in Northern Ontario can use studded tires. Non-Ontario residents can use them for up to 30 days in the province. Regulations specify the size and placement of studs. Using studded tires in Southern Ontario can lead to a $1,000 fine.

Ontario Trip Permits

If Ontario is not on your International Registration Plan (IRP) cab card, you can request the permit agency for a single-trip permit.

Ontario Fuel Permits

You should register for IFTA with Ontario if your commercial vehicle meets the following criteria:

  • Has two axles and a gross vehicle weight or registered gross vehicle weight exceeding 11,797 kg (26,000 pounds), or three or more axles regardless of weight, or a total registered gross vehicle weight exceeding 11,797 kg (26,000 pounds) when combined with a trailer.

  • Maintain vehicle records in Ontario or make them available to the Ontario Ministry of Finance.
  • The vehicle travels in Ontario and at least one other jurisdiction.

Recreational vehicles used solely for personal pleasure and vehicles associated with business operations are not considered qualified motor vehicles.

If you lack a valid IFTA license and occasionally travel into other jurisdictions, you can purchase a single-trip permit from authorized permit agents on a trip-by-trip basis. These permits allow conditional travel for one vehicle into another jurisdiction for a predetermined distance and time period, potentially incurring additional fees beyond fuel tax.

Ontario Specialty Permits

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

Before transporting a vehicle on the highways, the owner/operator must either obtain a special permit or show their intention to get one by contacting the Special Permits Office.

Project permits:

Project permits are for carriers handling repetitive moves of similar loads along designated routes. They’re valid for up to 6 months, depending on contract duration. Two types are available: regular (printed) and enhanced (emailed).

  • Enhanced: Weight varies, width up to 16.34 ft (4.99m), length up to 150 ft (45.75m).

Processing takes up to 15 business days, so apply at least 30 days before the start date. Applications must detail load specifics, with charges possible for discrepancies during the inspection.

Special vehicle configuration permits:

Special vehicle configuration permits cater to unique vehicle and load combinations deviating from Highway Traffic Act standards. They’re utilized for trials, pilot projects, cross-jurisdictional requests, specific municipal travel needs, and temporary adjustments during regulatory updates. Applicants may need to furnish safety, economic, or infrastructure assessments. Processing typically takes 15 business days or more, with costs varying.

Amber Light Permits:

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

Loading Zone Permits:

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