Vancouver is about as far west as you can go in Canada. It would never serve as a link to the Great Lakes nor would it be an Atlantic Ocean Port. Try Halifax for that.
Saskatoon and Regina could probably use Vancouver as a link; probably wheat and grains would be shipped to the Orient through Vancouver. But Regina and Saskatoon are in the mid west.
The best answer is A Pacific Ocean Port. It is almost right on the Pacific.
