Very quickly, there's no regulatory authority under the Canada Elections Act to deal with this kind of situation.
I would refer the committee to the procedure put in place during the last byelections, requiring all electors to display their faces at the time of voting to validate their admissibility for voting. The act provides that those who decline to do so are allowed to take an oath, and that's what occurred during the byelections. So those who refused to display their faces were required to take an oath. If they refused to take an oath, they were refused voting.
