I've proctored every exam for 30 years—I don't outsource my exams—and I've had exactly two students who did not have ID, and in both instances they had forgotten their ID. I don't know how they did it. They said they were driving home, which meant that they left their driver's licence at home too, so they were driving illegally, I presume. But they went home and got their ID. We're very liberal. We're not saying that it must be a university photo ID; we said anything with a photo. We would take a mass transit pass, OHIP, card a driver's licence, a passport, or a university card.
