Artibello, who is retired, says she has been playing the lottery since LOTTO MAX launched.
The avid sewer and crafter said she checked her tickets at home when she discovered she won big.
"I kept looking and double checking the numbers online. I just couldn't believe it," she said. "I told my sister and she said, 'Stop –you're lying!'"
Artibello plans to share her win with family.
"I will share with my sister, nieces and nephews and my good friend. I will also enjoy a more comfortable retirement and do some work around the house."
The winning ticket was purchased at Shoppers Drug Mart on Charlotte Street in Peterborough.
"I'm so happy. I never dreamed I would win.”
