OTTAWA – Many Canadians are now able to determine which calls can be trusted thanks to a new technology aimed at combating spoofed calls named STIR/SHAKEN*. Caller ID spoofing is frequently used in nuisance and fraudulent calls to mask the identity of the caller.

As of today, telecommunications service providers will certify whether a caller’s identity can be trusted by verifying the caller ID information for Internet Protocol-based voice calls. This new technology will help reduce the frequency and impact of caller ID spoofing. As service providers continue to upgrade their IP networks and offer compatible phones to their customers, more and more Canadians will be able to see the effects of STIR/SHAKEN.

Over the last several years, the CRTC has pursued a comprehensive strategy to combat nuisance and unsolicited calls. In addition to requiring STIR/SHAKEN, the CRTC has:

  • Encouraged service providers to offer their customers call-filtering services that provide advanced call-management features;
  • Asked providers to block certain types of calls within their networks;
  • Approved a trial of a new call-blocking measure using artificial intelligence developed by Bell Canada. Between July 2020 and October 2021, more than 1.1 billion calls were blocked before reaching Bell’s subscribers.

The CRTC is also working with the industry to develop a process to trace nuisance calls back to their points of origin.

“This new caller ID technology will empower Canadians to determine which calls are legitimate and worth answering, and which need to be treated with caution. As more providers upgrade their networks, STIR/SHAKEN will undoubtedly reduce spoofing and help Canadians regain peace of mind when answering phone calls.” – Ian Scott, Chairperson and CEO, CRTC

The CRTC says it continues to work with its domestic and international partners to address unsolicited and illegitimate telemarketing calls.
