Changes to the Heavy Truck Weight and Dimension Limits for Interprovincial Operations in Canada pave the way for truckers to use wide-base single tires at the same weight limits as duals right across Canada. 

The decision was made during the meeting of the Council of Ministers Responsible for Transportation and Highway Safety in late January. 

The Canadian Trucking Alliance (CTA) says the next step is for the provinces and territories to amend their regulations to reflect the recent changes, and in the interim, to offer permits to facilitate the movement of single tire-equipped vehicles.
