Understanding Ontario’s Trailer Requirements: Annual Inspection Stickers, CVOR, and Restricted “A” License

When it comes to towing trailers in Ontario, knowing the requirements for annual inspection stickers, CVOR, and Restricted “A” licenses is essential—especially since rules vary based on weight and use (commercial vs. personal). Here’s a breakdown to help you stay compliant and safe.

1. Annual Inspection Stickers: When Are They Needed?

  • Commercial Use: For trailers used in business, Ontario law requires an annual safety inspection if the gross weight(the combined weight of the vehicle, trailer, and load) exceeds 4,500 kg.
  • Personal Use: For personal or recreational towing, an inspection sticker is required if the GVWR of the truck/tow vehicle is above 6,500 kg.

Why It’s Important: Regular inspections keep both you and others on the road safe by ensuring trailers are in good working condition.

2. CVOR (Commercial Vehicle Operator’s Registration): Who Needs It?

  • Commercial Use: If your vehicle-trailer combination exceeds 4,500 kg in gross weight and is used for business, you’ll need a CVOR. This registration helps the Ministry of Transportation monitor commercial operators’ safety records.
  • Personal Use: A CVOR is not needed if the vehicle and trailer are strictly for personal use, not carrying any commercial cargo, and the GVWR of the truck is below 6,500 kg.

Key Takeaway: A CVOR is required if your trailer and towing vehicle combined exceed 4,500 kg and you’re operating commercially.

3. Restricted “A” License: When Is It Required?

  • Restricted “A” License for Personal Use: This license is necessary for towing heavier trailers above 4600 kg and without air brakes. Since our trailers don’t use air brakes, the Restricted “A” license will be sufficient for any of our trailers.
