Rugby league football (French: ligue de rugby) is a participation and spectator sport in Canada. The code was first introduced to Canada in the 20th century, but the game struggled to survive in a competitive sporting market. By the end of the century, rugby league had disappeared completely from Canada. The game was re-introduced to Canada in the early 21st century with the formation of a national team. The start of an amateur domestic competition saw rugby league grow. In 2017, professional rugby league arrived in Canada with the Toronto Wolfpack joining the predominantly British and French Rugby Football League system in the third tier League 1.
