History of Non-RTAC

Based on a joint government-industry research program, a Memorandum of Understanding Respecting a Federal-Provincial-Territorial Agreement on Vehicle Weights and Dimensions was signed and implemented in 1988. The purpose of the memorandum was to move toward national uniformity by implementing consistent vehicle weight, dimension and configuration regulatory principles across all jurisdictions. The end result was a vehicle designation by the Road Transportation Association of Canada (RTAC) that was adopted as a national standard.

RTAC standards came into force in Manitoba when the Vehicle Weights and Dimensions on Classes of Highways Regulation (MR575/88) was passed 1988. To lessen the effect that the new standard might have on existing vehicles, a second designation of non-RTAC was set out under regulation. Non-RTAC refers to all commercial vehicles that do not conform to the national standard designated as RTAC (Road Transportation Association of Canada).

Non-RTAC vehicles are subject to a second set of provisions with respect to maximum allowable weights and dimensions and vehicle configurations that are more restrictive and allow lower permissible weights and dimensions than RTAC vehicles. The end result is a complex set of rules established in legislation, some of which apply to RTAC vehicles and others that apply only to non-RTAC vehicles.

With the exception of Ontario, all other Canadian jurisdictions chose not have a non-RTAC designation in their respective legislation. Instead, they adopted a policy-based regime for permitting non-conforming vehicles.

The purpose of this process is to inform owner-operators of non-RTAC vehicles about the current proposal to amend MR 575/88 and discover how this might affect them.
