Ontario Tractor Trailer Weight and Dimension Limits

Ontario has regulations that are extremely descriptive, compared to others around the US and Canada. There are a large number of types of trucks that operate in Ontario, many of which are designed to travel into and through Michigan, Quebec and New York state. Trailers with 3, 4, 5, and 6 axles are commonly used to move heavy commodities. Ontario has also begun a LCV project with turnpike doubles being permitted along divided highways and access routes after submission of the route on the permit application. These heavy semi-trucks as well as B-Train combinations can operate at gross weights of 63,500 kgs, depending on the number of axles and configuration.
