TORONTO - A great-grandmother from Windsor, Ont., says she couldn't believe it when she won a Lotto 6-49 jackpot worth more than $3.6 million.

Helen Blahovich matched all six numbers in the Sept. 2 draw.

She says at first she thought she had just five numbers and didn't realize she had all six.

Blahovich says she plans to sharsse her windfall with her family.
