The 2nd Division's structure was altered in early 1940, reducing its number of machine-gun battalions from three to one. The Camerons and the Chaudières (now a rifle battalion) were reassigned to the newly mobilized 3rd Canadian Infantry Division, and the Winnipeg Grenadiers were sent to Jamaica for garrison duty, after which they returned to Canada then redeployed to Hong Kong, where they were captured when it fell to the Japanese on 25 December 1941.
