To answer your question, I'm from Canada and we do not hunt seals the only people that hunt seals are Eskimos and they hunt them for food and skins for clothing,maybe you should study world cultures a little harder :)
I'm in the US but all I can say is as far as I know they hunt seal, which are not endangered. They hunt like people hunt in the US. Good hunters use the meat and hyde . I'm sure Canada has irresponsible hunters (like everywhere) but I believe most are not like that.
