November 30, 2022 Deadline for Canadian TSPs – Second CRTC STIR/SHAKEN Status Reports

On November 30, 2022, all Telecommunications Service Providers (TSPs) required to fully implement STIR/SHAKEN as a condition of providing or offering services in Canada must file their second post-implementation STIR/SHAKEN status reports with the Canadian Radio-television and Telecommunications Commission (CRTC). TSPs can rely on the CRTC’s template, which adds additional optional questions not included in the first (May 2022) status report filing.

CRTC Decision 2021-123 requires all Canadian TSPs to 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,” does not exclude reseller TSPs. Thus, all TSPs must comply with CRTC STIR/SHAKEN requirements, including submitting the second status report by the end of this month.

Because status reports are published online by the CRTC once filed, TSPs should consider whether to submit both confidential and abridged, public versions.

If you have questions about the applicability of the CRTC’s STIR/SHAKEN requirements, need assistance with preparing the second status report or an SPC Token application, or have other CRTC compliance questions, please reach out to Ivan Zajicek at 703-714-1310 or

For questions about STIR/SHAKEN in the United States or general FCC Compliance questions, please contact Michael Donahue at 703-714-1319 or or Ronald Quirk at 703-714-1305 or
