As a Canadian travelling south, I didn’t even mind getting 70 dollars for 100 Canadian because most things are a lot cheaper in the US, so it evened out. People don’t realize how much socialism hurts the country and how expensive it makes things ie: being forced to put two languages on products.
You would be better off vacationing elsewhere now that the dollar is pretty much on par. Gas here is over a dollar a litre now, so that would be over 4 dollars a gallon.
I was there this summer for the first time since 2003; we only stayed for the day. The sales tax in Quebec is killer, and they really pared back (I think discontinued) the refund program (which was great; just the rebate on the hotel would give you a nice shopping spree in the duty-free shop). Places that were accustomed to Americans shopping are probably hurting now.
It still is a great place to visit; Quebec City & Ottawa were really nice when I was there back in the late 90s.
