Prize Scams are a type of mass marketing scam that targets its victims through mail, telephone or email. The message will include notification that you have won a prize and ask that you forward funds to cover fees or taxes prior to receiving the winnings.
In Canada, you are not required to pay any fees or taxes on prize winnings. If you have not entered a contest or have purchased a lottery ticket of any kind, this is more than likely a scam.
If you feel that you have been the target of a fraud, report it to your financial institution, Equifax and your local police.
