What Canada's DNCL is and how it differs from the US DNC list

What the DNCL is

When Canada's telemarketing regulations took effect in September 2008, they included a national DNC list called the DNCL — Do Not Call List. It functions as the Canadian equivalent of the US National DNC Registry: consumers register their phone numbers, and telemarketers are required to scrub their calling lists against the DNCL before dialing. The DNCL is administered under the authority of the CRTC (Canada).

Because the 2008 Canadian rules were explicitly modeled on the US FTC Telemarketing Sales Rule (TSR), the two frameworks share a common DNA. Both maintain a national suppression registry, both impose per-call disclosure obligations, and both provide exemptions for certain categories of callers.

Where the DNCL differs from the US registry

Despite the shared foundation, four differences stand out for outbound dialing teams.

• Newspaper subscription exemption: The US TSR exempts charities, surveys, and political organizations. Canada keeps all three of those and adds newspapers soliciting subscriptions as a fourth exempt category.
• Request-for-information grace period: A US telemarketer may re-contact a consumer who previously requested information for up to 3 months. In Canada that grace period is 6 months.
• Internal DNC retention: Canadian rules require businesses to maintain their own separate Internal DNC list and keep each consumer's entry on file for 3 years and 31 days from the date of the opt-out request. This is a hard minimum — you cannot purge a Canadian DNC entry after the standard US retention period.
• Immediate full disclosure: Canadian regulations require the calling company to identify itself and state the purpose of the call at the very start of each contact. The US TSR does not impose the same upfront-disclosure requirement.

Running suppression in VICIdial for Canadian campaigns

VICIdial handles DNCL suppression the same way it handles US DNC scrubbing — through Campaign DNC lists loaded before each campaign launch. The key operational difference is timing: because the DNCL is a paid subscription service in Canada, you need to schedule list downloads in advance of each campaign refresh cycle rather than relying on a free daily pull.

Your Internal DNC list for Canadian consumers must be stored separately from your US DNC records if you run cross-border campaigns. The 3-year-and-31-day retention rule applies per consumer, per opt-out request date, so your data model needs to capture the exact request timestamp rather than just a flag.

Calling hours still apply

Passing the DNCL scrub is necessary but not sufficient. Canadian regulations also restrict Permitted calling hours to 9:00 am – 9:30 pm weekdays and 10:00 am – 6:00 pm weekends in the consumer's local time. A number that is clean on the DNCL can still be an illegal call if it is dialed outside those windows.
