Below, an excerpt from the Official Rules for a current Holland America cruise line sweepstakes. My emphasis:
"If the potential winner is a Canadian resident (with the exception of Quebec, residents of which are not eligible to enter this sweepstakes), he/she will be required to answer unaided a time-limited, mathematical skill-testing question by telephone before the prize can be claimed."
Apparently, in Canada, you have to be good at math to win stuff. Who knew?
P.S. Happy Canada Day, everyone!
