 The National Register of Electors is a continuously @-@ updated permanent database of eligible electors for federal elections in Canada maintained by Elections Canada . It was established in December 1996 when Bill C @-@ 63 was granted royal assent by the Governor General of Canada , and the preliminary National Register of Electors was populated with data in April 1997 during the final Canada @-@ wide enumeration . It replaced a system which required door @-@ to @-@ door enumeration of eligible electors for each electoral event . The database contains basic information about electors : name , address , sex , and date of birth . An elector may register or update their personal information between elections , or may request to be excluded from it per the Canada Elections Act .
