Sikhs are some of my favorite fellow Canadians. The Sikh community puts a lot of effort into really integrating into the Canadian culture and it shows.
It really helps that Sikhism is a relatively young religion that didn't ask that much of individuals. We're just "below the fold" enough to not have too many prejudices attached to us. Even the keeping hair / turban stuff isn't really required unless you want to.
Come to think of it, that's probably true of most Hindus too. I think it's just the Abrahamic religions that have too deep a history of conflicts within the western world.
