They probably already have you fingerprints.
No they do not. I've never been fingerprinted as a Canadian until I got a work visa for the USA. For many Canadians who visit the usa for tourism or similar will never have their fingerprints in a canadian or us database under current laws.
I arrived two weeks ago, no finger print required.
