Important: This article is general information for business and marketing operations. It is not legal advice. CASL interpretation depends on your specific activities, records, and exemptions. Consult qualified Canadian legal counsel before changing compliance policy or if you receive a complaint or inquiry from the CRTC.
B2B teams often assume CASL is a consumer-marketing problem. Outbound prospecting, nurture sequences, event follow-ups, and partner announcements can be commercial electronic messages when they promote a product, service, or business opportunity. Specific exemptions may apply. The operational task is to classify messages, retain evidence of consent or an exemption, and maintain suppression records as lists and tools multiply.
What CASL expects at a high level
For non-exempt commercial electronic messages to Canadian recipients, senders generally need valid consent, clear identification, and a working unsubscribe mechanism. Messages must also be truthful in their subject lines and body — misleading headers and content are separately prohibited. The framework is purpose-built for accountability: regulators can ask what consent you had, what the contact agreed to, and how quickly you honoured an unsubscribe.
Consent in B2B contexts
Express consent — an affirmative opt-in with clear disclosure — is the most durable basis for ongoing outreach. Implied consent may apply in narrower situations, such as certain existing business relationships or published business contact addresses, but it is time-limited and fact-specific. Sales teams should not treat a trade-show badge scan or a LinkedIn connection as consent unless your counsel confirms it meets CASL’s requirements and you document it.
Identification and unsubscribe
Non-exempt commercial electronic messages need sender identification and contact information. An unsubscribe mechanism must remain valid for at least 60 days after sending; requests must be honoured without delay and no later than 10 business days. For multi-brand organizations, be clear about which legal entity is sending the message.
Operational practices that hold up
Compliance is mostly workflow design. Centralize list ownership so marketing, sales development, and partner teams are not maintaining parallel spreadsheets with different suppression rules. Tag contacts with consent source and date at capture — web form, contract, event, inbound inquiry — so downstream automation can filter correctly. A general request for a quote or callback should not be recorded as express consent to future promotional messages.
Separate transactional messages — order confirmations, service notices tied to an existing agreement — from promotional campaigns where your policy requires different consent. When in doubt, route the message type through counsel review rather than guessing in a template editor.
B2B outreach scenarios to document
Inbound leads. Capture what the form disclosed, what boxes were checked, and whether future marketing was included. Store the submission record with the contact.
Cold outreach lists. Document provenance and consent basis before import. Lists without verifiable consent history are a common source of complaints.
Renewal and account messages. Messages about an active service may differ from prospecting pitches — classify each template and confirm basis with counsel.
SMS and text. Short-message channels need the same consent discipline as email; opt-out keywords and platform suppressions should mirror CRM rules.
Operational checklist
- 01Map the channels that send commercial electronic messages, including email and SMS, and who owns each.
- 02Document consent basis per contact: express, implied, or not eligible — with date and source.
- 03Standardize sender identification and contact block in all templates.
- 04Verify unsubscribe links and reply-to paths work on every template before launch.
- 05Process unsubscribe requests without delay and check suppressions across each electronic-message tool before further outreach.
- 06Separate transactional messages from promotional sequences where policy requires it.
- 07Review purchased or imported lists for consent provenance before any send.
- 08Train staff that personal inboxes and ad-hoc outreach still fall under CASL when commercial.
- 09Retain consent and unsubscribe records in line with your retention policy.
- 10Schedule a quarterly audit of active sequences and list sources.
Put the checklist to work
Assign an owner for consent records, message templates and suppression lists. Review those records before a campaign goes out, and make the unsubscribe path easy to test. This guide is a starting point for your own legal review, not a substitute for it.
