rv camping in Canada, different than camping in the US?

Big Difference-$$$. Camping in US national parks with the senior pass runs around $12/day with free entrance. In Canada the pass is not recognized so the fee could be 2 to 3 times as much and a pass is required daily as I recall. Also, higher fuel. Nevertheless, the Canadian Rockies are awesome so, within the overall cost of RVing, the extra wouldn't be a reason not to go. I don't think we made reservations but it would be safer to.
