Ontario couple's $50M lottery win to be reviewed

A couple from Hawkesbury, Ont., who have the winning ticket for the $50 million Lotto Max jackpot must wait before claiming the prize because of their past ownership of a convenience store that sold lottery tickets.

Jo Ann Champagne, 49, and her husband, Gaétan, 51, owned Jo's Depanneur for 12 years before selling it in October, and until recently Jo Ann was also employed at the store.

Ontario Lottery and Gaming Corporation said Wednesday that because each had been employed as lottery retailers within the past year they must be investigated under the OLG’s "insider wins" process.

The jackpot-winning ticket was purchased at Pharmaprix in Hawkesbury.

An OLG spokesman said the process of review should take about six weeks.

The Champagnes had travelled to Toronto on Tuesday to claim the prize Wednesday morning.
