US Invasion of Canada 1935?

[David_Hayward (RIP)]

Invasion of Canada Plan
has an interesting study on the possible invasion of Canada by the USA.

I can't say whether this is bogus although the original author was with the Queens University in Kingston. Also until from say 1925 until at least 1935 the British were concerned that there might have been a war with the USA. It seems incredulous now but it's true that this was considered a distinct possibility
