 In 1914, the Canadian Expeditionary Force (CEF) was created in response to a call by the United Kingdom for soldiers.The CEF was a separate entity from the Permanent Active Militia (by now also known as the Permanent Force, or PF) and the Non-Permanent Active Militia or NPAM.Regiments and other units of the Militia were not mobilized, but rather transferred personnel to the CEF for overseas employment.
