All trailers require stop, turn and tail lamps, as well as a license plate lamp. A trailer also must be equipped with at least one red reflector at the rear of the trailer, either separate or incorporated into a tail lamp, that is mounted at a height of not less than 38 cm and not more than 1.83 m.
A trailer with an overall width of 2.05 m or more, or a trailer having a gross weight in excess of 1400 kg, must be equipped with at least two amber reflectors mounted on the side of the trailer near the front, two amber reflectors mounted on the side of the trailer near the end and two red reflectors mounted on the rear of the trailer.
A commercial trailer with a width of more than 2.05 m and a GVWR of more than 4536 kg must be equipped with reflective markings on the rear and side of the trailer to meet the approved standards established by the Motor Vehicle Safety Act (Canada) and the applicable Society of Automotive Engineers (SAE) standards. These federal standards are available in the “Trailers: Federal Lighting Equipment Location Requirements” handout found at Inspection Stations and other locations.
Manufactured trailers have additional federal lighting requirements listed in the same handout. Requirements may include marker lamps, clearance lamps and conspicuity treatments, such as reflective tape.
All lamps must be SAE or Department of Transport approved.
The hitch and mounting hardware must be of adequate size and capacity to fit the towing unit’s coupling device properly and to handle the weight of the trailer. The device which couples the trailer to your motor vehicle must be firmly attached to a structurally adequate integral part of the frame of each vehicle, or, where the towed vehicle is of a GVW of less than 900 kg, to a structurally adequate part of the frame of the towed vehicle. Your vehicle must be equipped and connected with an auxiliary coupling device consisting of a chain or metal cable equal in strength to the principal coupling device, unless the coupling device is a fifth wheel and a kingpin assembly is used to couple a semi trailer to a truck tractor.
