I would like to get back to Mr. Hill's comment regarding the date of birth. This should not be used as proof of identity but only as a validation. It is easy to find out the birth date of anyone. This must be recognized.
Suppose I shaved my head for a campaign in favour of Leucan before having the picture taken for my health card and that three years later I show this picture to the scrutineer. Since my appearance will have changed greatly, this scrutineer could, on his own initiative, ask my date of birth. So this would be a tool for validation, but not identification.
I am going to explain how things are done in Quebec. All this screening takes place when people who come to vote enter the polling station. There is always an agent designated by the returning officer in charge of directing people to the proper table. Depending on their address, he directs them to a given section. It is also this individual who asks voters to show photo identification. If the voter says he does not have any, he or she is immediately directed to the attestation table. This is not being done at the polling table.
