This phone number is associated with a Canadian Lottery Scam.  Be aware, Canadian lotteries charge no 'taxes' or other fees. Also, anytime you receive a check or money orders from someone you don't know (even internet "friends"), and are asked to send some or all of the funds back to your friend or to another individual, the check will be counterfeit and you will be liable for the funds that are used.  You may even be reported to Chex Systems as a security risk to your bank.
Another number on the 'award letter' is 204-951-0625.
