From a CBC interview ( edit Apr 2010: link now dead) with Ignatieff on his (not written for any political gain) book.
Solomon: You know that the Conservatives are going to comb through this for everything. Every moment where ignatieff may miss it to prove that he’s not a true patriot. Once you say, I’m a patriot, boy, you better walk it. There is one thing that I caught, I have to mention it to you... you say "as Canadians, we cheer for the same football teams as Americans." This is talking about how similar the two cultures are. But no, we don't! We cheer for the CFL.
Ignatieff: No, not true. Not true. That’s a piece of--
Ignatieff: That’s…Look. There are people who love the Hamilton Tiger Cats and the Montreal Allouettes, and etc., but, there are lots of Canadians-
Solomon: Who love the nfl. ( I like how he answers the question for Iggy)
Ignatieff: Who love the NFL, that’s all I'm saying. And I don't want to cast negative aspersions on the CFL.
Solomon: It’s a national institution. ( more help from the CBC)
Ignatieff: Yeah, it’s a great national institution. I've watched it all my life. But there are also Canadians who watch the NFL.
There is lots here but look at the last comment from Ignatieff where he says he watched the CFL all of his life. Umm, I am not 100% sure on this, but some how I don't think that the CFL gets much coverage in England at the best of times and I doubt that during the 20 years that he spent over there that the BBC ever broadcast ANY CFL games.
So how did he watch?
