The revised and official list will have the date of birth on it, which is provided for in Bill C-31. It amends section 107 for that purpose, so that polling officials can identify and confirm someone's date of birth for the purposes of dealing with voter fraud. The address is something that almost must be used for that purpose. But the point of this amendment, and a number of these other amendments, would be to add that date of birth to lists that are distributed to candidates and parties and MPs as well.
