http://www.cic.gc.ca/english/citizen/look/look-16e.htmlPivotal to Canada's election process is the national register of voters....
In Canada, we maintain a permanent national register of eligible voters. It contains basic information about each person: name, address, sex and date of birth. The information in the National Register of Electors is used to produce the preliminary voters lists for federal elections, by-elections and referendums. About 20 percent of elector information changes every year.
16 % due to address changes
2 % new additions due to persons reaching 18
1 % new citizens added
1 % removed due to deaths
The data is kept current through the cooperation of many federal and provincial agencies (tax, motor vehicle, vital statistics, immigration etc) in addition to targeted mail-outs to potential eligible voters.
Eligible voters not on the list may register anytime including election day. Because of Elections Canada's extrordinary effort to maintain the National Register:
a) very few eligible voters are not registered (including first-time voters)
b) dead people do not inflate the list
c) duplicate registrations are minimized
