What would you prioritise on a cross-Canada roadtrip with an eight year old?

Moving from Quebec to the west coast and driving from Quebec City to Vancouver from the 22nd to the 28th. We don't have a huge amount of time for stops, and we definitely want to hit up the Royal Tyrrell museum in Drumheller.

What would you folks suggest as must-see stops along the way? Campsites, lunch stops, places we could spend fifteen minutes or an hour along the way? We'll be visiting a few friends in Winnipeg and either Calgary or Edmonton; there's only about an 80km difference between hitting Ottawa (which my daughter has never seen) vs Abitibi (which neither of us has visited). My current thought is to drive hard at the beginning to get through Ontario and the prairies, and take it a bit slower through the west since there's so much natural beauty to see.

Thanks in advance for ideas!
