The Best Man actor said that he believes his Canadian heritage has informed his sense of humour and approach to comedy.
When Parade asked him why so many comic actors - including Michael J Fox, Jim Carrey and Mike Myers - come from Canada, he responded: "I think there's a certain objectivity that comes from being Canadian.
"You're partly British and partly American; you have a good bird's eye view of both countries. So much of the comedy that comes out of Canada is impersonation - it's less 'look at me' than it is 'look at me playing other people'."
McCormack also discussed whether he has taken part in Canada's most popular sport, ice hockey.
"No hockey for me! It was encouraged, but it didn't take," he said. "I used to joke that there'd be much less violence if you just gave every player a puck; then they wouldn't have to fight over it."
