A record $64 million Lotto 6/49 jackpot was up for grabs Saturday night, and the chance to win big had many Canadians dreaming of how they'd spend the extra cash.

In Calgary, one family already knows what they'd do with a multi-million dollar jackpot: they'd give it all away.

Tom Crist won $40 million in a Lotto Max draw in May, 2013.

Seven months later, in December of that year, he put on a pair of sunglasses, discreetly picked up his winnings, and vowed to donate every penny to charity.

He was so quiet about his win that he didn't even tell his daughter, Mandy Buckner. She says she found out about her father's luck on Facebook.

"(I said) 'Hey Dad, did you win the lottery?'" she told CTV Calgary. "I heard he donated it all. I wasn't surprised."

Crist quickly made headlines for his generous decision.

He started a foundation under his name, and made his first donation to a Calgary cancer centre, in honour of his wife, who passed away from the disease.

He plans to continue giving the rest of the money away to charities picked by his family, including Big Brothers and Big Sisters and the Ronald McDonald House.

"My youngest son loves animals so he wanted to donate to the zoo, so we donate to the local Calgary zoo," Buckner said. "There's a lot of grief support programs that I utilized after … Mom passed away, so (we give) to that."

Buckner said the family is completely supportive of Crist's decision to give away the money, and that they are grateful for the chance to contribute to causes that matter to them.

"That's what he wants and that's the plan. And we support it 100 per cent," she said. "It's an amazing opportunity for us."
