| Signature Scam — CRA Tax Debt Threat | Callers claiming to be from the Canada Revenue Agency demand immediate payment for alleged tax debts, threatening arrest or legal proceedings if payment is not made immediately — sometimes appearing with a 438 local number to seem legitimate to Montreal residents |
| Signature Scam — Fake Bank Fraud Alert | Callers pose as representatives from National Bank, Desjardins, BMO, or other major Montreal-based financial institutions, claiming suspicious activity on your account and requesting you verify your banking credentials, card numbers, or online banking passwords over the phone |
