About TAC

The Transportation Association of Canada (TAC) is a not-for-profit, membership-based association that provides a neutral forum to exchange ideas and information on technical guidelines and best practices related to the Canadian transportation and roadways sectors. TAC promotes the importance of transportation to Canada’s economic well-being, as well as safe, secure, efficient and environmentally and financially sustainable transportation services.

TAC does not set standards, but is THE source for roadway-related technical documents, best practices, and national guidelines that are referenced in many jurisdictions across the country.  These documents are sold / distributed via the TAC Bookstore

Engaging TAC members

TAC is governed by a Board of Directors elected from member federal/provincial/territorial departments of transportation; municipal governments; and the private sector, associations and academia.  The Board sets the strategic direction for the organization and oversees TAC’s robust and active complement of volunteer councils and committees.

TAC councils and committees serve as an ongoing forum for the dissemination of knowledge, the exchange of information and the discussion of a wide variety of issues to advance the state of knowledge in transportation.

This collective exchange between transportation professionals is the framework to develop and update TAC’s national guidelines and best practices. It also helps provide researched solutions to address the current and future challenges faced by the transportation industry. 

Participation in TAC councils and committees is limited to TAC members. There are many other reasons for organizations to consider TAC membership, including exclusive information, preferred pricing on a variety of products and services, and more.

The TAC Secretariat provides staff support for the Association's activities.  


The origins of the Transportation Association of Canada (TAC) date back to 1914, when the Canadian Good Roads Association (CGRA) was founded. CGRA was mainly concerned with the establishment of a superior national road network and was one of the main forces behind construction of the Trans-Canada Highway.

During the 1950s, CGRA became more involved with specialized technical activities and by the 1960s its role had broadened, resulting in a name change to the Roads and Transportation Association of Canada (RTAC) in 1970.

Throughout the 1970s and 1980s, RTAC continued to expand its mandate to include all modes of transport for passengers and freight, and, in 1990, the name of the organization was changed to the Transportation Association of Canada (TAC) to reflect the increased scope of activities.

In 2001, a more focused mandate was adopted, with a particular emphasis on roadway infrastructure and urban area transportation issues.
