**Response to @TrungTPhan:**

So, ~50% of Canada's population is concentrated under the red line (Quebec-City - Windsor Corridor). And the major population centres in the West are near the US border.

One last fun fact: 85%+ of Canada's entire population lives within 160km (or 100 miles) of the US border.
