Elections Canada has an online voter registration service (E-Registration) where you can: check whether you're registered to vote in federal elections; update your address on file; and fill in a printable form to register for the first time.  Most registration requests can be completed online. For the others, E-Registration fills in a printable form that you can sign and submit by mail or fax, along with copies of your proof of identity and address. 

The National Register of Electors (the Register) is the permanent database of Canadians aged 18 and older who are qualified to vote in federal elections and referendums. Created in 1997, the Register is continually updated using federal, provincial and territorial administrative and electoral data sources. Elections Canada uses information from the National Register of Electors to produce voters lists (lists of electors).
