A cold call to a number on the DNCL

Anonymised, illustrative composite. A Kelowna representative worked a purchased phone list for a new subdivision farm, dialling numbers at 8:15 in the morning before a showing. One recipient was registered on the National Do Not Call List and had never done business with the brokerage — and the call itself broke a second rule before the DNCL question was even reached.

At a glance

  • • British Columbia, a licensed representative cold-calls a purchased residential phone list to prospect a new farm area ahead of a listing push.
  • • A recipient on the National Do Not Call List answers at 8:15 a.m. on a weekday — before the permitted calling window even opens.
  • • The Unsolicited Telecommunications Rules restrict telemarketing to 9:00 a.m.–9:30 p.m. on weekdays and 10:00 a.m.–6:00 p.m. on weekends — a separate rule from DNCL registration itself.
  • • No prior relationship existed with the recipient, so no Existing Business Relationship exemption applied to either problem.

The situation

The representative had just picked up a new subdivision as a farm area and wanted phone coverage before the first open house. A list broker sold a residential phone file for the postal codes in question, with no indication of DNCL status attached. The representative worked the list manually starting at 8:15 a.m., ahead of a 9:30 showing, reasoning that an early call was more likely to reach someone before their workday started.

The fourth call of the morning reached a homeowner who said, calmly, that they were registered on the National Do Not Call List and asked to be removed from whatever list had produced the call. They also mentioned it was early. Both comments turned out to be separate, real problems.

The problem

The Unsolicited Telecommunications Rules, administered by the CRTC, set two independent constraints on telemarketing, and this call broke both. First, calling hours: telemarketing calls are restricted to “9:00 a.m. to 9:30 p.m. on weekdays… and 10:00 a.m. to 6:00 p.m. on weekends,” full stop, regardless of who is called. An 8:15 a.m. call is outside the permitted window even to a number that is not registered at all.

Second, the DNCL registration itself. A telemarketer may not call a registered number unless a specific exemption applies. The rules define an Existing Business Relationship exemption on an eighteen-month window for a prior purchase and a six-month window for a prior inquiry — deliberately different numbers from CASL's email consent windows, and not to be confused with them. Neither window existed here: this homeowner had never purchased anything from, or inquired with, this representative or brokerage.

The rules are also explicit that there is no real-estate carve-out to fall back on: no real estate-specific exemption appears in these rules. A licence to trade in real estate does not double as a licence to call a registered number.

The numbers

The representative had worked through roughly 40 numbers from the purchased list before the 9:30 showing, starting at 8:15 — a 75-minute window entirely outside the permitted calling hours on both counts. Of those 40, an unknown but nonzero share were plausibly DNCL-registered, since the list had never been screened against the registry before dialling began.

The brokerage had registered its own telemarketing operation with the DNCL system, which is a separate step from actually screening a purchased list against the registry before calling it — registration establishes who is allowed to call; it does not clean a list of numbers that should not be called.

The rule that decided it

Two rules did the work, independently. The calling-hours restriction would have made the 8:15 call improper even against a fully consented list — it is a blanket restriction on timing, not a consent question. The DNCL restriction is the consent question, and the answer turned on whether an Existing Business Relationship existed on the eighteen-month/six-month clock the rules define. It did not.

Neither problem depended on what was said on the call, how the representative introduced themselves, or how the recipient reacted. Both are threshold questions — time of day, and registry status against relationship history — that have to be cleared before the phone is ever picked up.

The outcome

The brokerage suspended the cold-calling campaign against the purchased list and had it scrubbed against the current DNCL registry before any further calls, and moved the calling window to start no earlier than 9:00 a.m. The recipient's request to stop being called was honoured immediately, independent of any registry check, on the ordinary principle that a direct request always ends further contact regardless of what a list says.

No formal DNCL complaint was pursued past the recipient's initial comment on the call. The brokerage's broader response — screening every purchased list against the registry before it is worked, and fixing the calling-hours window in the CRM's dialler settings rather than leaving it to individual judgment — addressed both failure modes at once going forward.

The same calendar-versus-relationship confusion shows up on the email side of prospecting — see a purchased lead list with no consent trail for how CASL draws its own, different set of windows.

The tell

The tell was that the representative treated “is this number allowed to be called” as one question when it was actually two: is it inside the permitted hours, and is it clear of DNCL registration without an exemption. A purchased list that has not been screened against the current registry, worked at a convenient rather than a compliant hour, fails on both axes independently — and either one alone is enough to generate the complaint.

Takeaways

  • • Telemarketing calling hours — 9:00 a.m.–9:30 p.m. weekdays, 10:00 a.m.–6:00 p.m. weekends — apply regardless of DNCL status; an early call is a violation even to an unregistered number.
  • • The DNCL's Existing Business Relationship exemption runs on an 18-month purchase window and a 6-month inquiry window — different figures from CASL's 2-year/6-month windows, and not interchangeable with them.
  • • There is no real-estate-specific exemption in the Unsolicited Telecommunications Rules; a trading licence does not create a calling exemption.
  • • A purchased phone list has to be screened against the current DNCL registry before it is worked, not registered-as-a-caller and assumed clean.
