RE: Measures to reduce caller identification spoofing and to determine the origins of nuisance calls - Compliance and Enforcement and Telecom Decision CRTC 2018-32 – Telecom service providers’ progress reports

In Compliance and Enforcement and Telecom Decision CRTC 2018-32, the Canadian Radio-television and Telecommunications Commission (the Commission) determined that authentication and verification of caller ID information for Internet Protocol (IP) voice calls should be implemented by Canadian telecommunications service providers (TSPs) by no later than 31 March 2019 to empower Canadians to better protect themselves against nuisance calls. 

Toward that end, the Commission required TSPs to report on their progress by submitting to the CRTC Interconnection Steering Committee (CISC) a report every six months from the date of the decision (beginning 25 July 2018).  The Commission requested that CISC consolidate the TSP information and submit an industry progress report to the Commission every six months.

The CISC Network Working Group (NTWG) has developed a template for all TSPs to complete in an effort to ensure that information is provided in a consistent manner. 

According to records, the NTWG has not received your progress report, which was due on 25 January 2019. You are hereby requested to provide an update on your progress in implementing authentication/verification measures for caller ID by completing the attached template and sending it to Richard Polishak and Imen Arfaoui at no later than 8 March 2019.

If you have any questions with regards to this letter, please contact Imen Arfaoui at (819) 997-4663 or by email at
