The Canadian Radio-television and Telecommunications Commission defers the application of STIR/SHAKEN

The Canadian Radio-television and Telecommunications Commission approved a request to defer the application of STIR/SHAKEN to 911 and PSAP call back calls, that was scheduled to take effect on November 30.  The Commission was concerned that because of technology limitation 911 calls subject to STIR/SHAKEN could be misidentified as spoofed or dropped.

As a result, the Commission suspended the application of STIR/SHAKEN to 911 calls from end users to PSAPs, and to callbacks from PSAPs to end users.  The suspension will remain in effect only until a new implementation date is set by the Commission, based on the recommendation of the CRTC Interconnection Steering Committee (CISC).

The CISC was also required to file with the Commission, every six months beginning 31 May 2022 and continuing until the Commission decides otherwise, a report providing a complete update on these matters, with the second report including a recommendation as to the implementation date of the application of STIR/SHAKEN.
