Unless Canada's the nicest place on the earth, I doubt the award with no ticket thing. And there would be too many what if's even if they had video of someone with no ticket. What if I had given you the money to buy me a ticket, so it was my winning ticket. Paying out a winning ticket without the actual ticket would open a shit storm of potential law suits. A Friend hit at the casino for $35k a few years back. He had to sit at the machine and wait for the manager to come so he could get paid, the attendant told him if he got up from the machine for anything he wouldn't get the money as it hadn't been verified by the floor manager yet. No problem, except he had to piss like a race horse and he ended up having to sit there for a little over an hour before they showed up. He told me he was close to pissing himself 25 minutes in. Obviously if $35k's on the line if you couldn't help it, you'd piss yourself.
Lottery and casinos will look for any reason to not pay out a jackpot.
