Roller derby in Canada

Canadian roller derby leagues at one point were welcomed to join the Canadian Women's Flat Track Roller Derby Association, which in January 2012 renamed itself the Roller Derby Association of Canada. The Toronto Roller Derby League is the largest flat-track derby league in Canada. Many roller derby leagues enjoy support from their national skate federations, including Roller Sports Canada.

Contemporary roller derby has a basic set of rules, with variations reflecting the interests of a governing body's member leagues. The Women's Flat Track Derby Association (WFTDA) rules are used by the majority of leagues around the world. Members of the Roller Derby Association of Canada have been encouraged to join the WFTDA.
