Of course, you may be intersted in what Canadian Consular Affairs has to say about Canadians travelling to the US. Among other things:
When you are attempting to enter the U.S. (border crossing or airport) and until such time that you have been admitted or refused entry, you should be aware that under U.S. law, foreign nationals do not have the same rights as American citizens.
