Tow more than one vehicle in Ontario
Towing more than one vehicle in Ontario involves more than hooking a second trailer behind a pickup. The question usually means moving a disabled car, a project shell, and a support trailer in one trip, or using a combination that places two vehicles on or behind the tow unit. Ontario law treats this as a vehicle combination, so the driver must consider licensing class, braking requirements, drawbar connections, and the combined weight of every loaded trailer. The practical answer depends on whether the setup is a commercial transport operation, a roadside recovery using a flatbed with a trailer, or a private owner attempting a compound arrangement.
Essential answer
Ontario does not have a universal private-vehicle right to tow more than one vehicle in a casual double-trailer setup. A combination with two towed units generally behaves like a commercial combination vehicle, and its legality turns on the trailer configuration, coupler type, total combined weight, and the driver’s licence class. A pickup that is rated for a single gooseneck or bumper-pull trailer does not automatically gain the authority to pull a second trailer behind the first, even when each individual unit is under a published capacity.
The safe interpretation is to treat any plan with two towed vehicles as a multi-trailer vehicle combination. The gross vehicle weight rating of the tow unit, the axle ratings of each trailer, the tongue weight of the leading trailer, and the combined weight rating must all work together. When the leading trailer is a car hauler carrying one vehicle and the trailing unit is a tow dolly or small utility trailer, the rear trailer’s drawbar load and sway behavior change the whole assembly. A setup that is plausible on a private farm road may not meet the equipment and braking standards expected on a public highway.
