Who Regulates Business Phones in Canada? CRTC, ISED, CCTS

The short answer

Several bodies share the job, and which one matters depends on the problem:

• The CRTC sets the rules telephone companies must follow: number portability, 9-1-1, the National Do Not Call List, consumer codes such as the Wireless Code, and part of Canada's anti-spam law.
• ISED (Innovation, Science and Economic Development Canada) manages radio spectrum and certifies radio and telecom equipment. It does not hand out phone numbers.
• The Canadian Numbering Administrator (CNA) assigns area codes and exchange codes to carriers under CRTC oversight.
• The CCTS (Commission for Complaints for Telecom-television Services) is the free complaint desk once your provider has failed to fix a problem.
• The Office of the Privacy Commissioner of Canada (and in Quebec, the Commission d'accès à l'information) handles privacy; the Competition Bureau handles false or misleading advertising and deceptive telemarketing.

For a small business, the practical order is almost always: your provider first, the CCTS second, and a regulator only for rule breaches the CCTS does not handle. This guide reflects the rules as of October 2026 and is educational information, not legal advice.

The map: who regulates what

The CRTC: the rule-maker for phone companies

The CRTC describes itself as "an independent quasi-judicial tribunal that regulates the Canadian communications sector in the public interest." Its mandate comes from Parliament, administered through the Minister of Canadian Heritage, and its responsibilities include the Telecommunications Act, the Broadcasting Act, the Online News Act and Canada's Anti-Spam Legislation ^[1]. The Telecommunications Act (S.C. 1993, c. 38) is the statute that gives it power over telephone companies.

The CRTC regulates providers, not their customers. The rules that touch a small business phone most directly are:

Number portability. CRTC decisions are why you can take your number with you. Telecom Decision CRTC 2005-72 (20 December 2005) required wireless carriers to port numbers in and out, set a two-business-day interval for simple ports between wireless and wireline, and set 2.5 business hours for simple wireless-to-wireless ports ^[8]. Those intervals measure the carrier step for a simple, correct request, not the whole job; our article on how long number porting takes explains the difference.

9-1-1. "The CRTC regulates telephone and cell service companies. These companies create networks that make it possible to connect 9-1-1 calls to call centres." The call centres and emergency responders themselves "fall under the jurisdiction of provincial, territorial, and municipal governments" ^[9]. So a question about how your provider handles 9-1-1 goes to the CRTC; a question about how a 9-1-1 centre answered goes to your province or municipality. Our emergency calling page covers what this means for hosted numbers.

Telemarketing and the National Do Not Call List (DNCL). The CRTC runs the DNCL rules and the wider Unsolicited Telecommunications Rules. Telemarketers must identify themselves and the purpose of the call, display a number you can call back, and call only between 9:00 a.m. and 9:30 p.m. on weekdays and 10:00 a.m. and 6:00 p.m. on weekends. Calls to business numbers are exempt from the DNCL rules but still covered by the telemarketing and automatic dialing (ADAD) rules. The CRTC can impose penalties of up to $1,500 per violation for an individual and $15,000 for a corporation ^[10]. The CRTC is reviewing these rules (Compliance and Enforcement Notice of Consultation CRTC 2026-132; replies were due 11 August 2026). A consultation changes nothing until a decision issues, so the current rules apply ^[11].

Consumer codes. The CRTC has four mandatory consumer protection codes. Of these, the Wireless Code applies to individual and small business customers, defined as a business whose average monthly telecom bill is under $2,500; large corporate accounts are not covered. The Internet Code, TV Service Provider Code and Deposit and Disconnection Code have narrower scopes, and the Deposit and Disconnection Code applies to residential home phone service ^[12]. In practice that means a business cell plan may have code protections that a business landline or VoIP line does not.

What the CRTC does not do: it does not resolve individual billing disputes. That is the CCTS's job.

ISED: spectrum, equipment and the anti-spam website

ISED's telecom role is about the airwaves and the hardware. Its spectrum site describes the job as providing "access to the radiofrequency spectrum by issuing authorities for its use, minimizing interference" and covers licences, equipment certification, spectrum auctions and compliance and enforcement ^[2].

For a small business, ISED shows up in two places:

• Equipment. Phones, cordless handsets and radio devices sold in Canada go through ISED's certification processes. If you buy a cheap imported cordless system, it should carry Canadian certification.
• Anti-spam. ISED hosts the CASL information site and the Spam Reporting Centre ^[13]. It does not itself levy CASL penalties (see below).

ISED is often confused with the CRTC because both work on "telecom". A rough rule: ISED handles spectrum and devices; the CRTC handles services, prices and conduct of the companies selling them.

CNA and CNAC: who hands out Canadian numbers

Phone numbers in Canada are not issued by ISED or by the CRTC directly. The Canadian Numbering Administrator provides "a numbering administration service to the Canadian telecommunications industry under contract to the Canadian Numbering Administration Consortium Inc. (CNAC)", and the administration of Canadian numbering resources is "under the regulatory oversight" of the CRTC, following CRTC-approved guidelines such as the Canadian Central Office Code Assignment Guideline ^[3].

Canada shares country code 1 and the North American Numbering Plan with the United States and 18 Caribbean nations. A number is NXX-NXX-XXXX: a three-digit area code (NPA), a three-digit central office code, and a four-digit line number ^[3]. The CNA also chairs the relief planning committees that plan when a region gets a new overlay area code; the CRTC approves each one. For example, Telecom Decision CRTC 2026-190 (29 July 2026) approved area code 851 as an overlay on 782 and 902 in Nova Scotia and Prince Edward Island, effective 27 May 2028 ^[14].

What this means for you: you never deal with the CNA. Your provider (or its underlying carrier) holds blocks of numbers and assigns one to you. The CNA's own site lists area codes by province and announces relief plans.

CCTS: the free complaint desk

The CCTS is "a private, not-for-profit corporation incorporated under federal legislation" that receives no taxpayer money; the CRTC requires all telecom providers and most TV providers to participate in it and fund it ^[4].

A small business can file a complaint about telecom service if all three conditions hold ^[4]:

1. You have tried to resolve the problem directly with your provider and failed.
2. Your monthly bill for all telecom services is normally under $2,500.
3. The complaint is about unregulated wireless, internet, local phone (including directory listings, operator services or directory assistance), long distance, or a combination.

How it works: if the complaint is within its mandate, the CCTS sends it to the provider and gives the provider 20 calendar days to work with you directly. If that fails, the CCTS reviews the file and decides whether the provider "reasonably performed its obligations" under the contract and the codes. It can require providers to fix billing errors, restore wrongly suspended service, stop collection activity during the process, correct credit bureau reporting, give credits and, in appropriate cases, pay compensation. It cannot make a provider lower its prices or change its policies. The service is free ^[4].

What the CCTS will not take: complaints about services regulated by the CRTC (tariffed services), privacy complaints (sent to the OPC), false or misleading advertising (Competition Bureau), and unwanted telemarketing (National DNCL) ^[4].

Privacy and advertising: the OPC, the CAI and the Competition Bureau

Privacy. PIPEDA "sets the ground rules for how private-sector organizations collect, use, and disclose personal information in the course of for-profit, commercial activities across Canada," enforced by the Office of the Privacy Commissioner. Alberta, British Columbia and Quebec have their own private-sector privacy laws deemed substantially similar ^[5]. In Quebec, the Commission d'accès à l'information oversees the private-sector act (P-39.1). Call logs, voicemails and transcripts all contain personal information, which is why our privacy page sets out how they are handled.

Advertising and deceptive marketing. The Competition Bureau is "an independent law enforcement agency" whose remit includes false and misleading advertising and deceptive telemarketing ^[7]. A provider that advertises "unlimited" and then throttles, or a scam caller pretending to be your carrier, is in its territory.

CASL is split three ways. The CRTC can issue administrative monetary penalties for violations of sections 6 to 9 of CASL (the sending, alteration and software-installation rules); the Competition Bureau can seek penalties or criminal sanctions under the Competition Act; and the OPC handles address harvesting and illegal collection of personal information from devices ^[15]. CASL focuses on commercial electronic messages such as email and text messages ^[13]; live telemarketing calls fall under the CRTC's telemarketing rules described above.

Which door to knock on

Checklist for a Canadian small business

• Know your monthly telecom spend across all services; under $2,500 keeps you inside CCTS and Wireless Code coverage.
• Keep contracts, terms of service and the provider's critical information summary (for wireless) in one folder.
• Put every complaint to your provider in writing and note the date, name and ticket number. The CCTS will ask whether you tried.
• Before a port, keep the old service active until the new provider confirms the number has moved.
• If you call or text customers for marketing, read the CRTC telemarketing rules and CASL; they are separate regimes.
• Name a person responsible for privacy; accountability is the first of PIPEDA's ten principles ^[5], and Quebec's P-39.1 has its own rule.
• Keep a mobile or landline that can dial 9-1-1 at each workplace; check what your phone service can and cannot do.

FAQ

Is the CRTC the same as ISED? No. The CRTC is an independent tribunal that regulates communications services and companies ^[1]. ISED is a government department that manages spectrum and equipment certification ^[2].

Can the CCTS help with a number port? The CCTS does not list porting as its own category. If the problem is how a participating provider handled your service and you meet the eligibility tests, file and let the CCTS decide whether it is in scope ^[4].

Who regulates VoIP? The CRTC regulates VoIP providers that offer local service, including their 9-1-1 obligations, and the CCTS takes complaints about local phone service, including VoIP providers that participate. Our Canada page summarizes the Canadian rules that apply to a hosted phone number.

Does the CRTC set phone prices? For most retail services, no; competition sets prices, and the CCTS will not review whether a price is too high ^[4].

Is this legal advice? No. This is a plain-language map as of October 2026. For a specific dispute or compliance question, speak to a lawyer.
