This article explores the five crucial weight guidelines that every G license holder in Ontario must follow. It also highlights the types of vehicles you can legally operate, the risks of exceeding weight limits, and the importance of proper insurance coverage.

1. Maximum Weight Limit for a Class G Licence

According to Ontario’s licensing rules, a Class G licence allows you to operate:

• A vehicle with a gross weight of 11,000 kg or less, OR

• A motor vehicle towing a trailer, as long as:

  • The combined gross weight of the vehicle and trailer does not exceed 11,000 kg, AND

  • The trailer itself weighs 4,600 kg or less.

If either of these limits is exceeded, the driver requires a higher class of licence, such as Class D or Class A.

This makes it essential to check the vehicle’s registered gross weight, the trailer’s gross weight, and any cargo being carried.

2. Vehicles You Can Drive with a Class G Licence

A Class G licence permits operation of a wide range of everyday vehicles, provided they stay within the legal weight and trailer limits.

Permitted with Class G:

• Cars, minivans, SUVs

• Light-duty pickup trucks

• Vehicle + trailer combinations within Class G weight limits

A higher class is required when:

• The vehicle alone exceeds 11,000 kg

• The vehicle + trailer combination exceeds 11,000 kg

• The trailer exceeds 4,600 kg

If any part of the vehicle setup exceeds Class G thresholds, the driver must hold the proper licence class for that combination.

3. Towing Limits for Class G Drivers

Towing with a Class G licence is allowed, but only within specific limits:

• The combined gross weight of the vehicle, trailer, and load must be 11,000 kg or less.

• The trailer’s gross weight must be 4,600 kg or less.

If the trailer’s weight goes beyond 4,600 kg, or if the total combination exceeds 11,000 kg, a Class G licence is no longer valid. In most cases, this moves into Class A or Class D requirements.

Always verify weights using the vehicle’s manufacturer information and the trailer’s rating before towing.

4. Consequences of Exceeding Class G Weight Rules

Driving a vehicle or vehicle-trailer combination that exceeds the limits of a Class G licence can lead to several issues:

• You may be legally required to hold a higher class of licence.

• Enforcement officers can restrict operation or require the vehicle to be taken out of service.

• You may face administrative penalties for operating outside your licence class.

The official rules make it clear: operating a heavier vehicle or trailer than your licence allows places you into a different licence class and must be treated as such.

5. Importance of Staying Within Weight Limits for Insurance and Legal Compliance

While the MTO focuses on licensing classification, exceeding the limits of a Class G licence can have wider implications:

• Your insurance may require that the vehicle and licence class match legal driving requirements.

• Operating a vehicle requiring a higher class of licence while holding only Class G can cause coverage issues if an incident occurs.

• Drivers planning to use heavier vehicles or trailers must confirm both licence class requirements and insurance rules.

Ensuring your licence matches the vehicle or combination you operate is essential for full legal and insurance compliance.

Final Thoughts: Follow These Guidelines to Stay Compliant

The official Ontario rules for Class G licences can be summarized as follows:

• Vehicle alone: Must be 11,000 kg or less

• Vehicle + trailer: Combined weight must be 11,000 kg or less

• Trailer alone: Must be 4,600 kg or less

If any of these limits are exceeded, you must upgrade to a higher licence class such as Class D or Class A.

Staying within Class G weight limits ensures you remain legally compliant, avoid licence-class violations, and maintain proper insurance coverage.
