If I missed your real point, and you were more interested in homosexuality and how it exists here, then sorry, I shall do my best to answer now.
Yes, (most) Canadians are far less interested in whether two people of the same sex want to marry. I don't personally devote much time to thinking about homosexuality, or marriage for that matter. But since this subject is important to you - basically adults can marry consenting adults here. Except no poligamy yet... but technically it would not stand a serious legal revue, as any contract that consenting adults wish to enter into that causes no harm should be legal...
Seems that a lot of Canadians move here, especially in the entertainment industry. Why don't they stay there and work in your entertainment industry?
Are you guys really proud of Celine?
