RV and Trailer Towing Rules in Ontario
Towing a trailer behind a regular vehicle and driving a larger motorhome are treated differently under Ontario licensing rules — and the motorhome side of this changed in 2025.
Quick answer: A standard Class G licence lets a driver tow a single trailer weighing up to 4,600 kg gross vehicle weight behind a regular vehicle, and towing more than one trailer at a time isn't permitted for non-commercial vehicles. Driving a larger, self-propelled motorhome is a separate question: as of mid-2025, Ontario introduced updated weight tiers and a Recreational Vehicle Learning Module (RVLM) course tied to driving bigger motorhomes on a Class E, F, or G licence without a full commercial licence.
Key Takeaways
- A Class G licence covers towing a single trailer up to 4,600 kg GVW behind a regular vehicle.
- Towing more than one trailer at once generally isn't permitted for a non-commercial vehicle.
- Driving a motorhome itself (not towing) is governed separately, with weight-based tiers that were updated in 2025.
- Ontario introduced a Recreational Vehicle Learning Module (RVLM) course connected to these updated motorhome rules.
Towing a trailer behind a regular vehicle
For most drivers hauling a travel trailer, boat trailer, or similar unit behind a car, SUV, or pickup truck, a standard Class G licence is sufficient, provided the trailer's gross vehicle weight doesn't exceed 4,600 kg. Ontario's rules for non-commercial vehicles also don't permit towing more than one trailer at the same time, regardless of each individual trailer's weight.
Driving a motorhome: a separate set of rules
Driving a self-propelled motorhome -- rather than towing a trailer behind another vehicle -- is governed differently, based on the motorhome's own weight. A full commercial licence (Class A, B, C, or D) covers operating a motorhome of any weight. For drivers who hold a Class E, F, or G licence instead, Ontario updated its framework in 2025: these licence classes can now cover driving a motorhome up to 14,000 kg with a new RV endorsement added to the licence, or up to 11,000 kg without that endorsement. Ontario also introduced a Recreational Vehicle Learning Module -- an online course -- connected to this updated framework.
Why the distinction matters
The practical difference is between what's being towed and what's being driven. A regular vehicle towing a trailer within the 4,600 kg limit stays squarely within standard Class G rules. A large motorhome driven on its own power, though, is evaluated by its own weight against the newer tiers, which can mean an RV endorsement is required depending on how heavy the specific motorhome is. Because these rules were updated in 2025, a driver considering a larger motorhome purchase should confirm the current weight thresholds and endorsement requirements directly with the Ministry of Transportation rather than relying on older information.
Frequently Asked Questions

Yes, for a single trailer up to 4,600 kg gross vehicle weight. Towing more than one trailer at a time generally isn't permitted for non-commercial vehicles.
Do I need a commercial licence to drive a large motorhome?
Not necessarily. Since 2025, a Class E, F, or G licence can cover driving a motorhome up to 14,000 kg with a new RV endorsement, or up to 11,000 kg without one, depending on the vehicle's weight.
What is the RVLM course?
The Recreational Vehicle Learning Module is an online course Ontario introduced alongside its 2025 update to motorhome licensing rules.
