A winning lottery ticket worth a record-breaking $64 million is still unclaimed more than a week after the jackpot draw.

The Lotto 649 ticket was sold at an outlet in Mississauga, Ont., sometime before the draw on Saturday, Oct. 17. Officials have yet to reveal exactly where the ticket was purchased, hoping the winner or winners will come forward first.

The ticket is worth $64 million, setting a new record for the largest single Canadian lottery prize, the Ontario Lottery and Gaming Corporation (OLG) said at the time of the draw.

Nine days after the win was announced, OLG said the ticket's owner has yet to come forward. If the ticket had been claimed and deposited in a Canadian bank account, the winner could have already earned $20,000 in interest.

However, the delay is not unusual.

"Sometimes they wait 24 hours, sometimes it's 24 days, sometimes it's a few months. You never know what, really, is in the psyche of our big winners," OLG's Tony Bitonti said Monday.

The ticket holder has one year from the date of the draw to claim their prize, he said.

Bitonti said some winners wait to get their financial affairs in order before coming forward. Others want to tell their family and friends privately before claiming the prize, since they know their name will be publicly released.

"Who knows who'd come out of the woodwork in that person's life," one woman told CTV Toronto, adding that she wasn't the winner.

"If all of a sudden you claimed a $64-million prize, you might have to play it smart."

OLG officials advised the winner or winners to register the ticket as soon as possible, by scanning the ticket at any lottery retailer. Tickets can also be checked at the OLG Prize Centre in Toronto, on Dundas Street just west of Yonge Street.

Once the ticket has been registered, OLG can begin the process of paying out the record-breaking jackpot.

The previous lottery jackpot record was set last month, when a Lotto Max ticket worth $60 million was purchased in Brampton, Ont., approximately 20 kilometres northwest of Mississauga.

A group of 12 colleagues from Markham, Ont., split the prize, receiving $5 million each.
