Butch & Co.A good guess, but a friend in Toronto offers contradictory evidence -- here's Maple Leaf Stadium in 1946:

In the foreground, beyond the center field fence, "Little Norway," a base and barracks for the Norweigian Air Force during WWII, here already converted to public housing.
Clearly, a lot more territory there between the outfield and the waterfront than appear in Bert's photo. Would also expect to see the area beyond the grandstand much more urbanized if that were actually Toronto.
Bert, can you read any of the ads on the grandstand facade? One is for a cement company... can't make out any further details. If it's a local outfit, that might nail down the city...
