The MacTier Cup is the name of the championship for the top senior men's rugby league in Canada. Originally awarded to the champion of the Rugby Canada Super League (RCSL), the MacTier Cup was established in 1998 along with the RCSL. The first MacTier Cup Championship match was played between the Vancouver Island Crimson Tide and the Nova Scotia Keiths. Vancouver Island defeated Halifax in that game. The champions of the final RCSL championship were the Newfoundland Rock, who won the cup in 2008 after defeating the Calgary Mavericks 30–6.
