around that time. Burke defeated Mr. Sekigawa to win the North American Heavyweight Championship but lost it to Bret Hart later that year. He regained it in a rematch but dropped it to Hart once again. Burke returned to Canada's Atlantic Coast briefly to compete for Atlantic Grand Prix Wrestling (AGPW) and won the promotion's North American Tag Team Championship with Hubert Gallant. They lost the belts to Cuban Assassin and Bobby Bass that summer, but Burke was able to regain the championship by teaming with Stephen Petitpas. AGPW only promoted shows in the summer, and Burke then returned to Calgary during AGPW's off-season; while there, he teamed with his brother Bobby Burke again to regain the International Tag Team Championship in December 1980.
