To just back up a little bit, with the current paper-based petition system we have, those signatures are currently verified. How the clerk verifies them from my understanding is, they are just looked at to see whether all the signatures look the same, whether it is the same handwriting for all of them. If so, the petition is ruled out of order. It is kind of a quick eyeball test.
If you do the electronic petitions, of course, you have this wonderful thing called an IP address that you can study. With the addition of e-mails being sent back, you can verify where people are from. It actually is a more robust signature than what we currently have.
Depending on what rules you deem to adopt, the way I was looking at this it would really be people only from within Canada. If the committee were to change the Standing Orders to say that it could be from Canadians outside of Canada, one way the U.S. deals with that is to make people pre-register before they sign up. They just indicate their country of origin, that they're Canadian, that type of thing. In fact, I think this would make it a little easier if you're registering things online, just because of the IP address and the ability to use e-mails as a kind of a proxy signature.
