Rugby Canada is the national governing body for the sport of rugby union in Canada.
 Rugby Canada was incorporated in 1974, and stems from the Canadian Rugby Football Union, a body established in 1884 that now governs amateur Canadian football as Football Canada; and the now-defunct Rugby Union of Canada, established in 1929.
 Rugby Canada administers the Canada national rugby union team and sanctions the Rugby Canada National Junior Championship, a national competition for under-20 men's teams.
 It previously sanctioned the Super League as the premier level of men's competition in the country, but scrapped that league after the Americas Rugby Championship was created in 2009 as a two-stage competition in which the first involved only Canadian teams.
The history of rugby union follows from various football games played long before the 19th century, but it was not until the middle of that century that the rules were formulated and codified.
 The code of football later known as rugby union can be traced to three events: the first set of written rules in 1845, the Blackheath Club's decision to leave the Football Association in 1863 and the formation of the Rugby Football Union in 1871.
 The code was originally known simply as "rugby football".
 It was not until a schism in 1895, over the payment of players, which resulted in the formation of the separate code of rugby league, that the name "rugby union" was used to differentiate the original rugby code.
 For most of its history, rugby was a strictly amateur football code, and the sport's administrators frequently imposed bans and restrictions on players who they viewed as professional.
 It was not until 1995 that rugby union was declared an "open" game, and thus professionalism was sanctioned by the code's governing body, World Rugby — then known as the International Rugby Football Board (IRFB).
