Through its partnerships, The Road Authority (TRA) plays a key role in product prequalification across Ontario, both at the provincial and municipal level.

TRA hosts and publishes the Ontario Ministry of Transportation (MTO) Designated Sources for Materials (DSM). TRA Membership is a prerequisite of being on the DSM.

Many Ontario municipalities require products to obtain the Products Management Committee "A" as a prerequisite to prequalification.
