A plebiscite on conscription was held in Canada on 27 April 1942. It was held in response to the Conservative Party lobbying Prime Minister William Lyon Mackenzie King (Liberal leader) to introduce compulsory overseas military service, the government having previously promised not to introduce same in 1940. The result was 66% voting in favour, with Quebec being the only province to have a majority voting against. Quebec's strong majority against the commitment's release prompted the prime minister not to pursue the issue until later events prompted a change in position.
