 Legislation was later introduced to amend the type of data collected and stored in the National Register of Electors . On 17 May 2007 , the Privacy Commissioner of Canada Jennifer Stoddart appeared before the Standing Senate Committee on Legal and Constitutional Affairs regarding Bill C @-@ 31 , An Act to amend the Canada Elections Act and the Public Service Employment Act submitting a letter in which she criticised the proposed changes to the Elections Act . One of the problems was the inclusion of an elector 's date of birth in the voter lists sent to polling stations on election day for use by polling clerks and scrutineers ; Stoddart stated that verification of an elector 's birth year would be sufficient . The second problem she raised was inclusion of the date of birth in the voter lists sent to each candidate for all electoral districts in Canada , and also to all political parties .
