CRTC recommends implementation of 9-8-8 suicide prevention hotline

The Canadian Radio-television and Telecommunications Commission (CRTC) recommended implementing the three-digit code 9-8-8 for the nationwide suicide prevention hotline. This decision followed the US Federal Communications Commission's adoption of 9-8-8 as the National Suicide Prevention Lifeline number. The 988 code was already in use as a local exchange in the Yellowknife area within area code 867, which would require ten-digit dialing.
