On the Threashold Gifts page the caption reads:

"Air Canada Altitude members are showered with exclusive gifts. Simply put, the more you travel the world with Air Canada and the Star Alliance member airlines, the more Threshold Gifts you'll receive - because travel is a reason to celebrate. The gifts outlined below remain valid through February 2014."

I'd be extremely upset if any of the currently advertised gifts are no longer available, especially with the statement 'valid through February 2014'.
