I currently live in Canada, so I don't experience that. But if I look up a recipe and it is on foodnetwork.com I immediately get a modal popup saying "Hello Canada! Were you looking for Food Network Canada?" asking me if I wanted to go to foodnetwork.ca. If I choose that option, it doesn't take me to the recipe on the Canadian site, it just takes me to the homepage. Utterly useless.

But, that's not because of a language thing. My guess is that it's a rights thing. The US and Canadian brands are probably owned by different entities, and there's an agreement to try to redirect all traffic hitting .com to the .ca site. I don't know if that's the case for IGN, but it could be.
