Canada Approves Wartime Draft

In a special plebiscite, millions voted to release the Canadian government from previous commitments limiting military service methods. The majority's 'yes' vote was a personal victory for Prime Minister Mackenzie King, who had threatened to resign if the outcome was unfavorable. Quebec was the only province to oppose, reminiscent of its stance during World War I. Canada has sent tens of thousands of volunteers to various fronts, and now drafted men may also serve overseas. The election results have approved new manpower for victory.
