** Update **
It turns out this is a common requirement in Canada for competitions based on chance.
VMWare recently announced a competition for registered users who update their profiles. The prize is an Apple iPhone, while not a particularly tempting piece of technology in my opinion it would be good to flog on eBay for some quick beer money.
Being an anal retentive bastard I decided to read the fine print, if only to ensure that being an Australian I would actually be able to claim the damn prize.
(4) SELECTION OF WINNER: The winner will be determined by random drawing of all eligible entries received that month. Odds of winning a prize are based on the number of entries received each month. Winner will be notified by telephone or e-mail within ten (10) business days of the drawing, at which time a full shipping address and phone number will be required for fulfillment of award. Winner will have ten (10) days from notification to accept the prize by mail. Canadian residents, if selected as a winner, must correctly answer a mathematical skill-testing question in order to receive a prize. VMware is not responsible for late, lost, misdirected, or unsuccessful efforts to notify the winner. All taxes on prizes, including income taxes, and any incidental expenses associated with collection of a prize are the responsibility of the winner. Winners assume all liability for any damages caused or claimed to be caused by participation or by any prize and release VMware from any such liability.

receiving the prize. If the selected winner cannot be contacted, is ineligible, fails to claim a prize, or fails to return the completed and executed declaration and releases in a timely manner as required, prizes may be forfeited and an alternative winner selected.
