Recognized as world champion in Quebec after defeating Ed Don George to unify the AWA, NWA and NYSAC World Heavyweight Championships. Although O'Mahoney is defeated by Dick Shikat for the unified title in New York City on March 2, 1936, he is still recognized as world champion by the Montreal Athletic Commission on July 3, 1936.
Yvon Robert is stripped of the AWA World Heavyweight Championship in February 1938 after refusing to defend the title against Lou Thesz. He is still recognized as world champion in Montreal and a separate championship is created as a result.
The Masked Marvel refuses to unmask after the match and the Montreal Athletic Commission withholds his purse. The masked wrestler continues to be recognized as world champion in Ontario, however, this short-lived offshoot of the Montreal title was abandoned in January 1939.
Numa was not recognized as champion by the Montreal Athletic Commission until May 28, 1940, claiming that the Quebec City commission did not consult with the MAC over its decision.
This was a Best 2-out-of-3 Falls match. Robert regains the MAC title, however, the AWA and NWA initially refused to recognize Robert as champion due to the controversial finish in the third fall. Robert lost the NWA title to Bobby Managoff in Houston, Texas on November 27, 1942.
This was a Best 2-out-of-3 Falls match. Awarded via forfeit when Rocca cannot continue after losing the second fall to even the match at one fall each.
The title was renamed the IWA International Heavyweight Championship after Johnny Rougeau and Bob Langevin took over the International Wrestling Association on May 6, 1965.
