Canadian Automobile Sport Clubs (CASC) was the national governing body for auto racing in Canada from 1958 to 1988.

Its origins stretched back to 1951, when three independent car clubs met in Kingston, Ontario to found the Canadian Auto Sport Committee (CASC).

In 1951, inventor, engineer and MG race driver Marshall Smith Green came from Montreal to meet in Kingston with designer Jack Luck.

CASC's FIA accreditation was revoked at the international body's next General Assembly, and its powers were instilled upon a single associate of Ecclestone's, Benoit Mailloux, the president of the Federation de l’Automobile Quebec, until handed over to a new body, ASN Canada FIA, in 1990.

Details of the CASC history can be found in the book The Chequered Past: Sports Car Racing & Rallying in Canada 1951 - 1991 by David A Charters.
