The 2015 Mackenzie Cup playoffs were not held due to the withdrawal of the Powell River Regals from the Senior 'AAA' competition for 2015 on January 1, 2015. The Regals were the only registered Senior 'AAA' team in the province of British Columbia. The event was scheduled to match up the provincial champions of Alberta and British Columbia for the Pacific region qualifying spot for the 2015 Allan Cup. With the withdrawal of the Regals the Alberta provincial champion advanced directly to the Allan Cup tournament.
The province of Alberta had only 5 registered teams at the senior 'AAA' level; all of them played in the Chinook Hockey League. So the league playoffs doubled as the 2015 Alberta Senior 'AAA' Playoffs. The Bentley Generals won the championship on March 22nd defeating the Innisfail Eagles 4 games to none in the final.
