Here are a couple of things we noticed on our visit that I don't think have been mention before (these are our observations and may not reflect all areas of Canada):
Make sure to have a different credit card if you are used to using Discover. We were in the Canada in 2013 and couldn't find a single place that would take the Discover Card.
I don't know if this is the norm, but we found that even some commercial campgrounds will charge for the use of their showers. We were OK, but traveling with 5 people in our RV we liked the option of using campground showers sometimes.
