 Following the results of the Otter Commission, two more infantry regiments were integrated into PAM, 22nd Battalion (French Canadian) of the CEF (later renamed the Royal 22nd Regiment), and Princess Patricia's Canadian Light Infantry.In the midst of demobilization after the end of World War I, PAM strength was reduced to nearly its pre-World War I levels, with 381 officers, and 3744 soldiers of other ranks.The force would maintain this relative size until the eve of World War II.
