If I understand it, there must be a balance between facilitating voter participation and maintaining the integrity of the voting system.
In order to maintain the integrity of the vote, from what I understand of Bill C-31, we must be able to identify voters who want to exercise their franchise on voting day.
Bill C-31 specifically requires that a birth date be entered on the list of electors. This appears to me to be the will of Parliament. I would not want to create the illusion that I could change that will; however, my concern would be to ensure that this information is used only as required in order to facilitate the vote.
