One big difference between Americans and Canadians is the degree of patriotism displayed publicly.We Canadians prefer to murmur or just look on while our national anthem is sung while our American friends are not shy about belting it out.The Canadian flag flies at our provincial and national sites....in the U.S. you can find an American flag flying just about anywhere.
There are lots of other differences between Americans and Canadians,this is just one observation....makes for an interesting conversation between us.
