CAMBRIDGE - Desperately seeking rightful owner of an unclaimed $50-million Lotto Max prize. Ticket purchased at Cambridge store nearly a year ago. Winning numbers are: 3 10 13 23 31 41 45. Must be claimed by Nov. 30, 2013, or else money goes back into the lottery pool as bonus prizes.

Someone out there is going to be filthy rich or is going to kick themself, perhaps 50 million times.

With time running out on the ticket’s expiration date – a little more than a month before the Nov. 30 deadline – that lucky $50-million ticket is out there somewhere, just waiting to make someone’s bank account runneth over. If it expires, it will be the largest unclaimed prize in Canadian history.

“So far no one has come forward to claim the prize yet,” confirmed Tony Bitonti, senior manager of media relations at the Ontario Lottery and Gaming Commission.
