Telecommunications Service Providers (TSPs) offering and providing telecommunications services pursuant to the Telecommunications Act in Canada must, pursuant to an April 6, 2021 Canadian Radio-television and Telecommunications Commission (CRTC) decision (Decision):
- File STIR/SHAKEN implementation readiness assessment reports (Assessment Reports) by August 31, 2021;
- Implement STIR/SHAKEN to authenticate and verify caller identification information for Internet Protocol (IP)-based voice calls by November 30, 2021; and
- Submit status reports every six months starting May 31, 2022.
TSPs must implement STIR/SHAKEN to authenticate and verify caller ID information for IP-based calls “on whatever IP portions of the network exist,” including any portion of a TSP’s network “able to initiate, transit, or terminate IP-based calls.”
In a related decision, the CRTC directed the Canadian Secure Token Governance Authority (CST-GA) to work with currently ineligible TSPs (without access to Canadian Numbering Administrator resources) to develop new eligibility requirements that only prevent “TSPs that cannot be trusted to maintain the integrity of the STIR/SHAKEN framework” from directly receiving Secure Telephone Identity (STI) Certificates, necessary for higher attestation levels, from the CST-GA.
If you have questions about the applicability of the CRTC’s STIR/SHAKEN requirements, need assistance with Assessment Reports or status reports, wish to be involved in developing STI Certificate eligibility, or have other CRTC compliance questions, please reach out to Ivan Zajicek at 703-714-1310 or firstname.lastname@example.org.
