Rugby union in Canada

Rugby union (French: rugby à XV) is a moderately popular sport in Canada. It is a strong participation sport, particularly in hotspots like British Columbia, Atlantic Canada (particularly in Nova Scotia and Newfoundland and Labrador), the West Island of Montreal, Quebec City and Ontario. However, it does not attract the same level of spectator support yet, possibly due to the CFL's success as the dominant football code in the country. Rugby Canada is the administrative body for rugby union in Canada. Each province also has its own union.

As of 2024 Canada has over 12,000 seniors and over 21,000 junior and minor players throughout the country. The Rugby Canada National Junior Championship for under-20 players is organised solely within Canada by Rugby Canada.

Canada is classified by World Rugby (WR) as a tier two rugby nation. Tier two nations do not have a full-time professional domestic structure in place, but they are considered by WR to be the most promising countries in which to expand the sport. The Canadian national men's side have competed in every Rugby World Cup to date, aside from the 2023 Rugby World Cup. The 1991 tournament was their most successful, as they reached the quarterfinals.

Canada's climate is a potential barrier to participation as many grounds are under snow or ice for significant portions of the year, leading to a split season. Canada has long been a regional power in Rugby Americas North, albeit in one of the sport's weaker regions in which there is no tier I nation.
