Yay Canada! How far west will you be when you come up? When I was younger we'd always take camping trips in the summer and head west to the mountains. Drumheller is pretty cool in Alberta, but I haven't been there in ages!
http://www.traveldrumheller.com/ and
http://www.discoveralberta.com/ have some cool things to see out there. If you go down into North Dakota, you will drive through my province, Saskatchewan
Cypress hills is beautiful, and it is located in southern alberta and Saskatchewan. If you do make it up this far you'll have to check it out!

I would assume you would be traveling on the Trans-Canada highway, which passes through Regina, which is only 2 hours south of me.
http://www.transcanadahighway.com/ If you go this route, make sure to check out the Tunnels of Moose Jaw. I used to live there so I've been on both tours and they are very interesting! Moose Jaw also has a pretty cool mineral spa that you should stop at for a little dip in the pool
When I went to college there my friends and I would go once a week!
