Parts for trailers & semi-trailers in Canada

Updated 4 November 2026

A replacement trailer or semi-trailer part in Canada costs about CA$11 to CA$65 for LED lights, CA$305 to CA$440 for a commercial 22.5-inch tyre, and CA$160 to CA$1,290 for a hitch or fifth-wheel plate. Fenders range from about CA$90 to CA$1,400. Send the part, the trailer model and your city to BlaBlaPrice to get offers.

Lighting and construction rules

Federal rules set where trailer lights must be placed, and Transport Canada publishes the lighting location requirements that manufacturers and importers must follow. Trailer construction standards are governed by the federal Motor Vehicle Safety Act. Before you buy a replacement light or fender, check that it suits your trailer's make and year, and ask the seller which standard the part was certified to.

Length limits and permits

Rules on combined vehicle length and permits differ by province. Quebec sets a maximum length for combinations of road vehicles that tow other vehicles, and British Columbia's commercial transport rules set permit conditions for some semi-trailers. If a new hitch or deck changes the trailer's dimensions, check your province's limits before you drive it on the road.

Season and tyres

Canadian winters from December to February bring cold weather and road salt, and a worn light or a loose hitch is easy to miss in the dark months. November is a practical time to check and replace parts before winter. Tyres are the largest cost. One tyre maker's trailer warranty runs six years from the date of manufacture, so read the warranty certificate before you pay.

What to put in the request

State the part, the trailer type, the model and the year, and whether you need an original part or a compatible one. For tyres, give the size printed on the sidewall, such as 295/75R22.5, where the rim is in inches and the width is in millimetres. For hitches, give the weight rating, which Canadian listings often show in pounds (lb). Add your delivery city and say whether you need freight to a workshop.
