What are the load restrictions for grain trucks on Canadian highways?

The Provincial and Territorial governments in Canada have authority over the weight and dimension limits which apply to the highways within their boundaries.

The Memorandum of Understanding (MOU) on Interprovincial Weights and Dimensions is intended to provide improved uniformity in weight and dimension limits through establishment of minimum and/or maximum thresholds acceptable to all jurisdictions for eight configurations of vehicles commonly used in interprovincial transportation.  More information is available at:

Seasonal road restrictions are in place at certain times of the year on certain roads within the provinces particularly in the spring break-up period.

Sellers of U.S. grain wishing to deliver grain into Canada are advised to contact the provincial highways department prior to delivery to obtain the information necessary to ensure compliance with weight and dimension limits in the relevant provincial jurisdiction.  More information is available at the provincial government department of highways websites:
