Modern Canada in 1935 confronts the limits of avoiding war

What if modern Canada, including its infrastructure and military, was transported to 1935?

Stopping Nazi Germany might still require force, leaving Canada's leaders to decide whether avoiding war would permit something worse.

The scenario transfers Canada's infrastructure and armed forces to 1935, but political choices dominate the response. The concern is that modern leaders would still look for a way to remove Hitler without fighting. Hatred of war's human costs does not by itself settle whether resistance is justified, since defeat or submission can permit worse harm. International politics has no guaranteed police authority to enforce every norm or protect every smaller state. In this argument, Canada would still have to decide who was prepared to stop an aggressor and accept the costs.
