Visiting Canada 2017-150 year anniversary of national parks

Many of our best National Parks are not exactly on the beaten path. You will not see crowds like Yosemite or Mount Rushmore up here, Canada busy is no where near as busy as USA busy (no disrespect, we just have way less people). Ya some campgrounds will be full, and some trails will be busy. I went to PEI National Park during a county music festival (by mistake) and yes it was busy and wrist bands were in effect and it was full but well behaved. I would make reservations but I would not invest in riot gear :)
