BCH;

Yes they accept US currency there (and gladly) just expect your change to be in Canadian.

Getting in and out of Canada is fairly simple, just have your US passport handy along with a drivers license and similar identification for all of your party. By no means take any firearms into Canada; they really frown on that sort of thing. Canadian Customs folks are usually super nice, very efficient, and helpful to those who are open and honest about their business in Canada.

We traveled by ferry from Washington to Victoria BC last year and it was a great experience. As was our travel from Haines Alaska to White Horse and back to Skagway. Extremely nice folks all around, and some terrific eating as well.

BC and the Yukon are beautiful as are the Rockies in Alberta.
