The Task Force on Vehicle Weights and Dimensions Policy is a national committee comprising officials from the federal, provincial and territorial transportation departments with responsibility for pursuing greater national and/or regional uniformity of policies, regulations and enforcement practices for heavy vehicle weight and dimension limits within Canada

The Task Force reports to the Council of Deputy Ministers Responsible for Transportation and Highway Safety.


National standards for the weight and dimension limits of heavy vehicles used in interprovincial transportation are contained in a Federal/Provincial/Territorial Memorandum of Understanding (MOU).

Initially established in 1988, expansions to the scope of the agreement, and amendments to the standards have been developed by the Task Force since that time, and have been endorsed by the Council of Ministers Responsible for Transportation and Highway Safety at its meetings in 1991, 1994, 1997, 2004, 2008, 2009, 2011, 2014, 2016, 2019 and 2022.
