Canada Is Rethinking the Do Not Call List
Matthew Leo · Published August 12, 2026 · Canada Tech
Canada’s National Do Not Call List is being reconsidered at a moment when unwanted calls look very different from the telemarketing problem it was built to solve.
The CRTC’s review of the Unsolicited Telecommunications Rules reached its reply deadline on August 11, 2026. The regulator is examining the framework behind the National Do Not Call List, telemarketing rules and automated calls, almost two decades after the system was introduced.
The central question is no longer simply whether a company called someone who asked not to be called. Today’s nuisance-call problem also includes spoofed numbers, automated scams, overseas operations and callers that may have no intention of following Canadian rules in the first place.
The Do Not Call List still does something useful
The National Do Not Call List gives Canadians a formal way to tell legitimate telemarketers that they do not want unsolicited sales calls. Businesses making non-exempt telemarketing calls must register and subscribe to the list, and they are not supposed to call numbers that appear on it.
That still matters. A company that operates in Canada, values its reputation and can be identified by regulators has an incentive to follow the rules.
The CRTC’s current telemarketing guidance is careful not to oversell the system, though. It says registration can reduce unwanted telemarketing calls, not eliminate them.
That distinction has become more important with caller-ID spoofing and fraud.
Scammers do not care that your number is registered
A fraud operation pretending to be a bank, tax agency or parcel company is not going to check the National Do Not Call List before calling.
Caller-ID spoofing makes enforcement harder because the number on your screen may not be the number that actually placed the call. The CRTC explains that spoofing can have legitimate uses, but it is also commonly used to disguise fraudulent calls.
This is why people can register their number, follow every recommendation and still receive suspicious calls that appear to come from a local area code or familiar organization.
The Do Not Call List is primarily a compliance tool for telemarketing. It was never designed to be a universal spam firewall.
Canada has added network-level defences
The CRTC has required providers to adopt measures beyond the list itself. Universal call blocking targets calls with obviously invalid caller IDs, while STIR/SHAKEN technology is intended to help networks authenticate caller information on compatible IP-based calls.
Those tools address a different layer of the problem. Instead of asking whether a telemarketer had permission to call, they help networks decide whether the identity attached to a call can be trusted.
That is a more useful direction for modern fraud, but it is not perfect. Authentication does not prove that a caller is honest. A criminal can use a legitimately obtained number. Some calls also travel through systems where authentication information may be incomplete.
There is no single switch that can determine whether every incoming call is safe.
The rules need to distinguish nuisance calls from fraud
A modern review should separate at least three problems that are often bundled together.
The first is legal telemarketing that consumers simply do not want. The Do Not Call List is well suited to that.
The second is aggressive or non-compliant telemarketing by identifiable businesses. That is an enforcement problem, where penalties and complaint data matter.
The third is fraud. Fraudsters may spoof caller IDs, operate outside Canada or disappear before enforcement catches up. That requires network filtering, authentication, fraud intelligence and cooperation between telecom providers and law-enforcement agencies.
Trying to solve all three with one list creates unrealistic expectations.
Exemptions also confuse consumers
Not every organization is barred from calling numbers on the National Do Not Call List. Canada’s rules include exemptions for certain calls, and organizations can also have an existing business relationship or receive consent in ways that change what is permitted.
That can make the system feel broken even when a call is technically allowed.
A revised framework should explain exemptions more clearly at the consumer level. People should be able to answer a simple question: “Why was this organization allowed to call me?” without reading regulatory guidance written for telemarketers.
The list should become one layer in a larger anti-spam system
The National Do Not Call List does not need to disappear because it cannot stop every scam. That would be like removing seatbelts because they do not prevent collisions.
It does need to be positioned honestly.
Canada should keep a clear opt-out system for legitimate telemarketing, strengthen enforcement against businesses that ignore it, improve caller authentication, encourage effective carrier-level filtering and make complaint data useful enough to identify recurring abuse quickly.
Consumers should also have simpler tools on their phones and through their carriers to screen unknown callers without silencing every doctor, school, delivery driver or employer who is not already saved in Contacts.
A 2007 framework needs a 2026 definition of unwanted calls
The CRTC introduced the Unsolicited Telecommunications Rules framework in 2007. Since then, voice-over-IP calling, cheap international routing, automated dialling and caller-ID spoofing have changed the economics of unwanted calls.
The cost of placing millions of calls has fallen. The ability to make those calls appear local has improved. The distinction between an annoying sales pitch and an organized fraud attempt has become far more important.
Canada’s review should reflect that reality.
The Do Not Call List remains useful when the caller is a business that cares about Canadian law. The next version of the system has to be designed for all the callers that do not.
