I just think Canadians have a more easy-going way of doing things, and are more tolerant, I don't think it has much to do with how many scots where here at first, how many of the Canadians here have a direct link to the scots?
I don't think they wear kilts 1/2 as much in scotland as they do here,or U.S. for that matter.
except for weddings, games etc.
I think you may find that the first scots in the americas probly didnt wear or even own a kilt.they probly just wanted to blend in.it's not till recent times that they (the children of) felt comfortable enuf to wear a kilt.
