The 64-year-old said she has been playing the same numbers since they “came to her in a dream”.
She told OLG that she was “not having a very good day” when she walked into a store to check her lottery ticket.
“But it surely made my day when I saw the Big Winner message pop up,” Rose said. “I remember saying ‘What?’ And then started to cry! ”
Rose said she first told her grandchildren about the big prize because she always promised them she would win the lottery someday.
The mother-of-four, who has said the big win is unlikely to hit her until the money is in her bank account, plans to travel and share the winnings with her children.
“I really want to visit Greece, Turkey and Bulgaria,” Rose said.
The OLG said Rose’s winning ticket was purchased at Avondale on Main Street in Port Colborne.
