Canadian International Heavyweight Championship

The Canadian International Heavyweight Championship was the top singles title in the Montreal-based wrestling promotion Lutte Internationale (International Wrestling). It was the successor to the Montreal Athletic Commission's MAC World Heavyweight Championship (later renamed the International Heavyweight Championship), which was retired after the Commission's promotion, the International Wrestling Association, closed in 1975. The title was promoted from 1976 until Lutte Internationale closed in 1987, upon which the title was retired.

In 2024, the title was revived by the American promotion Total Nonstop Action Wrestling (TNA) as the International Heavyweight Wrestling Championship by A. J. Francis, with the explanation that Francis purchased the rights to the title and declared himself champion. This occurred on June 15, 2024 in Cicero, Illinois during the Impact! tapings which aired on June 27. It is currently unknown whether the title is an officially sanctioned title by TNA. The current champion is PCO in his first reign. He defeated Francis in a Montreal Street Fight at Slammiversary on July 20, 2024 in Montreal, Quebec.
