Page "British Commonwealth Air Training Plan" Paragraph 22

The government agreed in December 1939 to join the British Commonwealth Air Training Plan, operate its bases in Canada, and pick up a large proportion of the costs.

Events turned the scheme into a huge operation, one that cost Canada $ 1. 6 billion of a total cost of $ 2. 2 billion, and employed 104, 000 Canadians in airbases across the land.
