Yup loads of canucks are doing this. I live about 1 hour from the border and im not bothering wih those odds. Also, if you buy the ticket across the border (legally) then come back to canada and then cross back into the USA its actually considered illegal to bring the lotto ticket back into the USA. They have the right to seize the ticket if they find it amongst your belongings provided you are pulled over to be searched. Chances of being caught must be extremely low though
