Must see places in Canada?

I will be traveling from Barrie Ontario to Lake Louise AB on the Trans Canada Highway, and i dont want to miss anything along the way. What are some must see places?
I will be living in Lake Louise, Banff National Park

nods, head in agreement with the other suggestions. If you have the time, I would stop at Drumheller Alberta to see the museum there…it is an old dinosaur digging area, many of the skeletons found there are preserved and put back together in that museum. I found it fascinationg.
Aslo if you have time for a little detour, head south in Alberta along the foothills of the Rockies and go so the “Head smashed in buffalo Jump” museum. An awesome place to visit…it will take you all day just to see all of the 3 floors and investigate the walkway they have constructed at the top of the cliff where the buffalo were made to jump over.
