CASL and Telecommunications Act
CASL & The Telecommunications Act: Key Requirements for Organizations in Canada
Organizations operating in Canada must comply with both Canada’s Anti-Spam Legislation (CASL) and the Telecommunications Act, which set strict rules around electronic communications, marketing, and privacy.

1. Canada’s Anti-Spam Legislation (CASL)
CASL regulates commercial electronic messages (CEMs) to protect consumers from spam, phishing, and other digital threats.
What Organizations Must Do Under CASL:
✅ Obtain Consent – Before sending CEMs (e.g., emails, SMS, social media messages), organizations must have express or implied consent from recipients.
✅ Provide Identification – Every message must include accurate sender information, including the organization’s name, contact details, and address.
✅ Include an Unsubscribe Mechanism – CEMs must have a clear and easy-to-use unsubscribe option, and requests must be honored within 10 business days.
✅ Avoid Malicious Practices – Organizations must not use false or misleading sender information, install software without consent, or harvest email addresses.
✅ Record-Keeping – Maintain records of consent, including how and when it was obtained, in case of regulatory audits.
📌 Penalties: Non-compliance can result in fines up to $10 million for businesses and $1 million for individuals per violation.
CASL (Canada’s Anti-Spam Legislation) Compliance Checklist
✔ Obtain Consent Before Sending Commercial Electronic Messages (CEMs)
- Express Consent: The recipient has actively agreed (e.g., checked an opt-in box).
- Implied Consent: Exists if there is a business relationship (e.g., past purchase within 2 years).
- Maintain records of who gave consent, when, and how.
✔ Include Mandatory Information in All CEMs
- Business name, contact details, and postal address must be clearly visible.
- If sending on behalf of another party, both must be identified.
✔ Provide an Unsubscribe Mechanism
- Every CEM must have a clear, easy-to-use unsubscribe option.
- Opt-out requests must be processed within 10 business days.
✔ Avoid Misleading Information & Unauthorized Software Installations
- Do not use false sender names, misleading subject lines, or deceptive URLs.
- Obtain consent before installing software or tracking tools (e.g., cookies, apps).
✔ Maintain Compliance Records
- Keep records of all opt-ins, opt-outs, and communication consents.
✔ Regularly Train Staff on CASL Compliance
- Ensure marketing, sales, and IT teams understand CASL requirements.
2. The Telecommunications Act (Canada)
The Telecommunications Act governs telecommunications services, including phone calls, text messages, and internet-based communications.
What Organizations Must Do Under the Telecommunications Act:
✅ Follow Do Not Call List Rules – Organizations making telemarketing calls must register with the National Do Not Call List (DNCL) and ensure they do not contact numbers on the list.
✅ Obtain Consent for Marketing Calls – Telemarketers must have express consent to contact individuals, especially for automated calls (robocalls).
✅ Disclose Identity & Purpose – Callers must clearly identify themselves, their organization, and the reason for the call.
✅ Follow Time Restrictions – Telemarketing calls are only allowed between 9 AM – 9:30 PM (weekdays) and 10 AM – 6 PM (weekends) (local time of the recipient).
✅ Maintain an Internal Do Not Call List – Organizations must keep a separate internal list of individuals who request not to be contacted.
📌 Penalties: Non-compliance can lead to fines up to $15,000 per violation for corporations.
