Canadian cities didn't build many skyscrapers in the 1940's. But here's a couple from Montreal.
Shawinigan power building. Unusual because it is a legit art deco building, but it was built in 1949. It's still here today.
It was part of what was then the new downtown.
Another, the IATA headquarters, built in 1943. It's still here today, but has long been re-cladded by glass.
