Don Leo Jonathan
Mike later wrestled in British Columbia, where he had a series of matches against Don Leo Jonathan in 1970 and 1971. Mike wrestled for Championship Wrestling from Florida in the early 1970s. He participated in many battles royal and, because of his size, was difficult for opponents to throw over the top rope and eliminate. As a result, the promotion billed him as "the acknowledged king of battles royal" and promoted many of these matches as "featuring Man Mountain Mike". On one occasion in 1972, his participation led to a feud with Buddy Colt, as Colt caused Mike to be eliminated from a battle royal.
