CASL Implied Consent Expiry Calendar

Implied consent under Canada’s Anti-Spam Legislation (CASL) is time-limited and should be managed as an expiring relationship, not a permanent permission. This calendar template helps teams identify expiry windows, schedule suppression or re-permission tasks, and document decision points so contacts do not drift back into active campaigns after their implied consent ends.

Decision boundary: when implied consent expires

Implied consent arises from specific interactions (e.g., business relationships, inquiries, or existing transaction chains) and each category carries a defined expiry window; treat the expiry as a hard business rule for campaign eligibility. Use available regulatory guidance to map the initiating event to its expiry—if the event is a business transaction with an ongoing business relationship, the expiry is tied to the relationship’s end; for inquiries or estimates the expiry is generally shorter and based on the last contact date 1.

Evidence limitations: the Canadian regulator provides descriptive guidance and examples but not a granular event-by-event expiry matrix for every commercial scenario; teams must map their own product events to the high-level categories in CASL guidance. When in doubt, default to conservative expiry (shorter permission) and require explicit consent before resuming non-transactional messaging 1.

Practical sequence: build the expiry calendar

Step 1 — Inventory events that create implied consent: transactions, inquiries, referrals, or expressed interests. For each event capture the event date, data owner, and retention trigger (e.g., last purchase date, last invoice). Step 2 — Assign an expiry rule for each event type (e.g., 24 months from last purchase, 6 months from inquiry) informed by CASL categories and your legal/risk advice.

Operationalize: populate a rolling calendar that emits daily lists of contacts whose implied consent will expire in 30, 7, and 1 day intervals. Owners must confirm whether the contact should be moved to suppression, queued for a targeted re-permission flow, or routed to a region-specific handling stream (where local law or business practice differs).

Workflow actions at expiry and decision points

At expiry, perform one of three actions: suppress from non-transactional campaigns, launch a re-permission sequence, or route messages through a transactional-only channel if content fits an exemption. Define message types precisely: transactional communications permitted under CASL are limited; non-transactional promotional content requires consent. Document the selection criteria for each action and the owner who signs off on that choice.

Decision points to record: confirmation of last meaningful interaction date, whether a business relationship exception applies, whether the message qualifies as transactional, and whether any regional policy or contractual requirement changes the expiry treatment. Retain an audit trail of the action taken and the justification.

Automation and data model: fields to capture

Essential fields: contact_id, event_type (e.g., purchase/inquiry), event_date, implied_consent_start, implied_consent_expiry_date, expiry_action (suppress/re-permission/transactional-only), owner, and last_change_timestamp. Ensure your suppression list references implied_consent_expiry_date to avoid manual errors.

Failure modes and mitigations: stale event dates, duplicated contacts with differing event history, and missing owner assignments. Mitigate by enforcing a single canonical contact_id, normalizing event date sources, and requiring owner and justification fields to be populated before automated actions run.

Evidence limits, legal caution, and escalation

This template relies on the regulatory framing available from Canadian authorities; it does not replace legal advice. The regulator’s material provides guidance on implied consent categories but not a definitive per-business expiry for every scenario, so teams should consult counsel for novel use cases or high-risk communications 1.

Escalate to privacy or legal when: the commercial fact pattern is ambiguous (e.g., cross-border multi-entity relationships), the message content skirts transactional definitions, or a large segment is due to expire and the business impact is material. Log the escalation outcome alongside the calendar entry.

Practical checklist

• Map each event type that generates implied consent to an expiry rule and document the rationale.
• Add required fields (event_date, expiry_date, expiry_action, owner) to the contact data model.
• Create a rolling calendar that flags contacts at 30, 7, and 1 day(s) before expiry.
• Define three approved expiry actions: suppress, re-permission flow, or transactional-only routing.
• Implement automation guardrails: canonical contact_id, de-duplication, and owner sign-off.
• Log every expiry action and retain audit evidence for at least the statutory or internal retention period.
• Run a quarterly audit comparing suppression lists to expiry dates and correct mismatches.
• Escalate ambiguous cases to legal/privacy and record the decision in the calendar entry.
• Link expiry outcomes to suppression, re-permission, and regional routing systems to enforce actions.

Where RepMail fits

Use this calendar as an operational checklist and decision aid within your outbound workflows: populate the expiry fields in your contact system, trigger suppression or re-permission automation based on the calendar, and record owner decisions for audit. Do not assume product-specific automation behavior — validate integration points and retention policies with your vendor before relying on automated enforcement.
