What is E911?

E911, or Enhanced 9-1-1, is an emergency calling service that provides emergency operators with information such as the caller’s telephone number and location, helping emergency responders reach the person requiring assistance. CRTC

Emergency calling over VoIP can operate differently from traditional telephone service. A call may first reach a specialized emergency call center, where an operator confirms the caller’s location and callback number before transferring the call to the appropriate local emergency response center. Callers should always be prepared to provide their actual location and telephone number. CRTC

A mandatory CRTC requirement

Access to 9-1-1 is a mandatory regulatory requirement for providers of local telephone and local VoIP services in Canada, including resellers. It is not an optional service feature. The applicable requirements depend on the service being provided, including whether Basic or Enhanced 9-1-1 is required. Telecom Decision CRTC 2005-21 establishes emergency service obligations for local VoIP providers, and Telecom Regulatory Policy CRTC 2016-12 makes applicable 9-1-1 obligations directly enforceable against resellers. CRTC

Providing service through a wholesale, resale or white-label arrangement does not remove these obligations. Providers remain responsible for compliance when delivering local telephone services under their own brand, even when another carrier supplies the underlying network or emergency calling service. crtc.gc.ca

Proper listings are required for every account type

IXICA requires wholesale, resale, white-label and business accounts using its local voice services to have properly provisioned emergency calling and accurate E911 listings. Business customers must meet IXICA’s service and telephone-system configuration requirements; customers reselling telephone services must also fulfill their applicable CRTC obligations.

Proper provisioning includes the following:

  • Accurate physical location information. Emergency listings must identify the location where the service is used—not simply the billing address, reseller’s office, or corporate headquarters. Include relevant suite, floor, or building details, and update the information whenever a location changes. CRTC
  • A registered emergency caller ID. Every telephone number that can be presented as the caller ID on a 9-1-1 call must have the appropriate emergency listing. A separate listing is not necessarily required for every incoming telephone number if the telephone system reliably substitutes a registered emergency caller ID associated with the correct location. 
  • Correct telephone-system configuration. IXICA requires emergency calls to present a valid, provisioned callback number—not an anonymous identity, an internal extension, or an unregistered number. Telephone systems must override ordinary caller ID settings where necessary. The CRTC’s business telephone-system best practices also recommend direct 9-1-1 dialling without a prefix, where technically feasible, and a callback number reachable from outside the system. 
  • Appropriate arrangements for multiple locations and remote users. Each location must be accounted for through suitable emergency caller IDs, location records, and routing. A shared business telephone number must not cause callers at different premises to be incorrectly identified as calling from a single head-office address.

Customer notification and ongoing responsibilities

Providers of nomadic or fixed/non-native local VoIP services must explain the limitations of their emergency calling service and obtain the customer’s express acknowledgement before service begins. Required disclosures include information at sign-up and installation, in marketing materials and service terms, and through an accessible website link. Simply activating emergency calling does not satisfy the complete regulatory requirement. CRTC

VoIP emergency calling can be affected by power failures, Internet outages, equipment problems, and incorrect location records. Business customers must ensure that employees and other potential users understand these limitations and know to provide their current location when calling 9-1-1. CRTC

E911 service through IXICA

IXICA provides emergency calling services and E911 provisioning support. Customers and resellers must supply accurate information, maintain their listings, and ensure that their telephone systems present the correct emergency caller ID. Listings must be completed before users are given access to the service. Contact IXICA support to arrange authorized testing rather than placing an uncoordinated test call to 9-1-1.

Contact IXICA to arrange E911 service, review your listings, or confirm the requirements for your wholesale, resale, white-label or business account.

What is TTY/711 service?

TTY, short for teletypewriter, is an accessibility technology that allows people who are Deaf, deafened, hard of hearing, or have a speech disability to communicate over the telephone using text. TTY relay service forms part of Canada’s Message Relay Services (MRS) framework. crtc.gc.ca

A person using a compatible TTY device dials 711 to connect with a relay operator. The operator reads the caller’s typed messages aloud to the other party and types the spoken responses back to the TTY user. This allows both parties to hold a telephone conversation without needing to use the same communication method. Voice callers can also reach a TTY user through the relay service by dialling 1-800-855-0511. CRTC

A mandatory CRTC requirement

IXICA wholesale clients that provide local telephone or local VoIP services to customers in Canada—including resellers—must ensure that the required message relay services are available to their end-users. This is a regulatory obligation, not an optional service feature. Telecom Regulatory Policy CRTC 2018-466 confirms that local exchange carriers, resellers of local exchange services, and VoIP service providers must make MRS available 24 hours a day, seven days a week. crtc.gc.ca

Purchasing telephone services from an upstream carrier does not remove this responsibility. Telecom Decision CRTC 2006-12 specifically requires local exchange carriers to include the obligation to provide MRS access in their contracts or other arrangements with local VoIP service providers. CRTC

The requirement extends beyond 711 routing. The CRTC’s accessibility obligations cover both TTY relay service and IP relay service, including for fixed and nomadic local VoIP providers. IP relay allows users to communicate with a relay operator through an Internet-connected device instead of a traditional TTY. Simply enabling 711 dialling does not, by itself, satisfy the complete message relay requirement. CRTC

TTY/711 service through IXICA

IXICA provides TTY/711 relay service to wholesale clients, helping carriers and resellers make this accessibility service available to their customers.

Wholesale clients should coordinate with IXICA to arrange service, configure their telephone systems to route 711 calls correctly, and verify that access works for their end-users. Clients must also ensure that their broader relay obligations are addressed, including IP relay availability and accessible customer information about these services. The CRTC permits providers to fulfil their relay service obligations directly or through a third-party provider. CRTC
