What is CASL (Canada's Anti-Spam Legislation)?

Quick Answer

Canadian law requiring express consent before sending commercial electronic messages to Canadian recipients.

CASL is one of the strictest anti-spam laws globally. It requires express or implied consent before sending commercial email, SMS, or instant messages to Canadian residents. Express consent: recipient explicitly opted in. Implied consent: prior business relationship within 2 years. CASL requires identification of the sender, unsubscribe mechanism, and 10-business-day opt-out processing. Violations carry fines up to C$10 million per violation.
