Gregory and Tammy Nikolopolous arrived in Toronto to pick up the cheque on Monday with their children Caiden and Jennifer.
Gregory Nikolopolous says he checked his tickets on Saturday morning and says the first three were "donating to charity" and then he hit the winner.
He says he "screamed really loud" when he realized his ticket had won the jackpot.
Nikolopolous says the family are avid boaters and spend a lot of time on nearby Georgian Bay in the summer so they'll be shopping for a bigger boat.
Otherwise, he says they plan to take some time for themselves with immediate family and make sure everyone is "worry free."
