Scheme # 1.

This is coolbert:

Invasion USA! Canadians invade the United States! Canadians? Canada moves south? Could it have been?

"In 1921, Canada developed a secret plan to invade the U.S."

From Frank Jacobs | SEPTEMBER 5, 2018 courtesy the Internet web site bigthink.com

"America's fear of an Anglo-Japanese alliance led Canada to worry about a U.S. attack—and in the end, devise a scheme for a 'pre-emptive invasion' of its southern neighbor."

"Canada's 'Defense Scheme No. 1' called for a five-pronged attack on targets in the northern U.S."

WAR PLANS [WHETHER CANADIAN SCHEME # 1 OR USA PLAN RED] AS DEVISED PREDICATED ON THE ASSUMPTION OF A GENERAL WAR BETWEEN THE UNITED STATES AND GREAT BRITAIN. CANADA WOULD HAVE BEEN EXPECTED TO DO THEIR BIT. 

This map shows which routes the Canadians were contemplating. Here’s a summary of the General Instructions for Offensive Action listed in Defense Scheme No. 1:

The five axis of advance into the USA:

1. Canada’s Pacific Command.

2. Prairie Command.

3. Great Lakes Command.

4. Quebec Command.

5. Maritime Command. 

Again and further such a war with invasion USA based on the assumption of a general war between Great Britain and the USA:

"Because back then [1921], Canada was still firmly in the orbit of the British Empire. And the Brits were still not quite ready yet for a ‘Special Relationship’ with the U.S.—in fact, Britain’s demotion from a first- to a second-rate world power—which developed during and after the Second World War."

"The British after the First World War [and prior to that too] cultivated a special relationship with the Japanese Empire, then firmly in the ascendant. The Americans, already wary of Japanese competition in the Pacific, were worried about the risk of an Anglo-Japanese alliance, which had the potential to turn Canada into hostile territory in case of conflict between the U.S. and Japan."

Thankfully Scheme # 1 never came to fruition. Was however I might think good training for Canadian staff officers. One-hundred years later we can all rest easy now!
