Looking back on it, the arena and curling club are about what I'd have expected to see for Winnipeg circa 1910. But the stadium was surprisingly small... according to Wikipedia, Osborne Stadium opened in 1932 (although I'm not sure how accurate that is) and in pictures, it looks very cramped and ramshackle.
Compare it to Memorial Stadium down the road in Grand Forks, which was basically a small town at that time... theirs had nearly double the seating capacity and was much more impressive looking.
Memorial Stadium:
It's strange to me that the main stadium right in the middle of a major Canadian downtown area was so minimal... it didn't even have room for a regulation football field. It looks like something you might have expected to see in a place like Brandon.
