It was a Mother's Day to remember for a Toronto woman who picked up her $50-million cheque Tuesday afternoon.

Sophie Rizavas is Ontario's latest multimillionaire following her jackpot win in the May 9 Lotto Max draw.

The 63-year-old mother of two and grandmother went to a local retailer to check her ticket last Saturday evening and says she "saw a number of zeros" and thought she'd won $50,000.

And Rizavas says she couldn't believe it when a printed receipt came out of the machine at the counter with $50,000,000 in bold letters.

"I couldn't believe it. I just kept repeating, 'Oh my God!'" said Rizavas in an email statement on Tuesday. The man who helped process her winning ticket was crying and gave her a big hug, Rizavas said, 

She also won $5 for matching the first two numbers of her Encore play and Rizavas and her husband, Tom, announced the win to the family at dinner on Mother's Day.

As for her plans for the money, Rizavas says a family trip is the first thing on their list.

"We've never had a proper family vacation," Rizavas said. "We've tried over the years but someone's always had to stay home to work."

"It's quite a coincidence," she said. "My husband and I came to Canada from Greece on May 10, 1970, and 44 years later, May 10, 2014, we find out that we are multimillionaires."
