Hey Gary ~

Dunno why you're collecting documents ... HOW LONG are you going to be IN Canada?

Last time I went into Canada - June of 2005 - nobody wanted much in the way of ID ...
US side didn't even say G'Bye; Canadian girl wanted to see my Driver License going in.
Coming back - Canadians never even *waved* G'Bye; US side just wanted to know
if we'd bought anything in Canada.

I don't think the threat that you'd need a PASSPort to visit Canada ever went anywhere.

You should check before you go to the expense and bother of getting a PassPort.
