OTTAWA -- Somebody in this city spent $5 to make $48 million.

And somewhere, an OLG lottery machine starting flashing and ringing at 4:30 p.m. Saturday, when that lucky winner validated their ticket.

But officials won't say who it is and where the ticket was sold until next week -- when their "true winner" process is complete.

The sole jackpot-winning Lotto Max ticket for the March 28 draw was sold here.

As soon as a winning ticket is scanned -- either at a self-checker or by a store attendant -- the OLG is alerted.

OLG spokeswoman Dita Kuhtey said it's not unusual for that to take days or weeks.

In this case, it only took a few hours.

"Every player is different," she said, adding it's not known if the ticket was purchased by one person, a couple or a group.

"You should always sign your ticket as soon as you get it, keep it is the same safe place you always do -- and don't forget to check it," she said.

Kuhtey says if the winner self-checks their ticket as a kiosk, the prize amount will show up on the little screen. OLG will know right away the ticket has been checked.
