I received a "CLAIM NO" for a "WINNING FINAL NOTIFICATION" with a phone number to call before cashing the enclosed check (menat to cover taxes, reportedly).
The letter had no return address, with a post mark from CANADA and letter head from New York.
The TEL:1-416-731-9361 from Barbara Bryon (Promotion Manager) and Lewis McGregor (Claim Agent).
Susequent internet searches showed this same tactic being tried with multiple folks. The idea is to talk you into sharing your bank routing information for immediate & remote access to your bank account.
No dice here. Hope they are caught soon.
