The Rugby Canada Super League (RCSL or Super League) was a national, semi-professional rugby union competition in Canada. The league represented the second level of domestic rugby union in Canada, and the highest level wholly indigenous to Canada. In terms of seniority it rested immediately beneath the IRB sponsored North America 4, a former US/Canadian cross-border competition in which two Canadian teams (Canada East and Canada West) took part. Most players took part in RCSL ("Super League") on an amateur basis.
