Edwards was also one of four game show hosts to have emceed a game show in the United States and another in Canada concurrently (the other three were Howie Mandel, Alex Trebek and Jim Perry). Edwards, like Perry, commuted back and forth between and Canada between 1986 and 1991, hosting "The Big Spin" and the 1989 revival of "Jackpot!" in Sacramento, California and Glendale and the USA Network version of "Chain Reaction" in Montreal, Quebec. However, Edwards was required to have a Canadian co-host on "Chain Reaction", due to the fact that he had no ties to the country, unlike Trebek, Mandel and Perry (Trebek and Mandel are native Canadians; Perry had blood ties to Canada and lived in Toronto, Ontario during the first several years of "Definition"). His commuting days ended after "Chain Reaction" left the air in 1991. ("Chain Reaction"'s next incarnation would be in 2006 on GSN with Dylan Lane hosting.)
