A Canadian Radio-television and Telecommunications Commission (CRTC) [decision](https://commlawgroup.us2.list-manage.com/track/click?u=df51fe32659b5ffab92c23e59&id=6ae5e22aa4&e=9a2c2871d7) requires all Telecommunications Service Providers (TSPs) offering and providing telecommunications services in Canada must implement STIR/SHAKEN to authenticate and verify caller identification information for Internet Protocol (IP)-based voice calls by November 30, 2021.

To monitor STIR/SHAKEN implementation, the CRTC required all TSPs [submit](https://commlawgroup.us2.list-manage.com/track/click?u=df51fe32659b5ffab92c23e59&id=9db973f606&e=9a2c2871d7) STIR/SHAKEN implementation readiness assessment reports by August 31, 2021 and status reports every six months starting May 31, 2022. As STIR/SHAKEN implementation evolves, the CRTC has issued [decisions](https://commlawgroup.us2.list-manage.com/track/click?u=df51fe32659b5ffab92c23e59&id=6efb7fc210&e=9a2c2871d7) to remedy deficiencies. However, the CRTC has not exempted reseller TSPs, which do not own underlying network infrastructure and rely on underlying providers for STIR/SHAKEN implementation, from filing requirements.

All TSPs (including resellers), and particularly those that may have missed a filing deadline, should reach out to The CommLaw Group to ensure they are compliant and file required reports to avoid service disruptions or enforcement action.

*If you have questions about CRTC STIR/SHAKEN applicability and requirements, need assistance with preparing and filing Assessment Reports or status reports, or have other CRTC compliance questions, please reach out to ****Ivan Zajicek**** at ****703-714-1310**** or *[***isz@commlawgroup.com***](mailto:isz@commlawgroup.com)*.*
