 The Elections Act permits Elections Canada to synchronize the data in the National Register of Electors with information obtained from external parties . These include federal agencies and Crown corporations including the Canada Revenue Agency , Canada Post ( via the National Change of Address service ) , and Citizenship and Immigration Canada . The Act also specifies that Elections Canada may obtain information from other jurisdictions , such as from provincial and territorial motor vehicle registrars , and provincial electoral agencies with permanent voters lists . Since 1999 , Elections Canada has convened the Advisory Committee of Electoral Partners annually ( known as the National Register of Electors Advisory Committee until 2008 ) , usually in November in Ottawa , to discuss the permanent elector databases , data sharing arrangements , and other related topics .
