After Jack Tunney's death in 2004, there was some discussion of whether North Carolina-based promoter Jim Crockett was ever a partner in the Toronto office. Crockett and Frank Tunney worked together from 1978 to Tunney's death in 1983, and Jack and Eddie Tunney continued to work with Crockett for several more months until switching their allegiance to Vince McMahon and the WWF in 1984.
In Canada, during most of the 1970s and the early 1980s, there was a law called the Foreign Investment Review Act (FIRA) which regulated the foreign ownership of Canadian companies. In November 1980, the Canadian Press reported that the government had approved the creation of a new business called Frank Tunney Sports Promotion, which was co-owned by Frank Tunney Sports Ltd., Jim Crockett Promotions Inc., and 410430 Ontario Ltd., said to be based in Hamilton.
The owner of the numbered corporation wasn't identified (it would be a matter of public record, but you have to pay a service charge to access Ontario corporate records), but Hamilton native George Scott is thought to have been the third partner. He continued to own a part of the office after the affiliation with McMahon and is said to have received a large settlement after he was pushed out of that partnership.
