National Public Alerting System

The National Public Alerting System (NPAS) is a multi-channel Federal-Provincial-Territorial (FPT) all-hazards system that provides emergency management organizations throughout Canada with a standard alerting capability to warn the public of imminent or unfolding hazards to life through such means as radio, cable television, satellite television, email and SMS text services. The NPAS complements existing public alerting systems and tools in a number of FPT jurisdictions.

Following a 2009 decision by the Canadian Radio-television and Telecommunications Commission, Pelmorex Communications Inc. was designated as Canada's aggregator and disseminator of emergency public alert messages.  On June 9, 2010, Pelmorex launched the National Alert Aggregation and Dissemination (NAAD) System. 

The NAAD System is based on the Common Alerting Protocol (CAP), an international open data standard for exchanging public warnings and emergency messages between alerting technologies.  The NAAD System only accepts emergency alerts from Authorized Government Agencies.  These alerts are then made available in CAP format for broadcasters and other media distributors who voluntarily distribute them to the Canadian public.

For more information on the NAAD System and currently participating jurisdictions in the NPAS / NAAD initiatives, please consult the Pelmorex web site.

The Canadian Profile of the Common Alerting Protocol (CAP) is a set of rules, and managed lists of values, that are recommended for use in Canada. It is often referred to as the CAP-Canadian Profile or simply CAP-CP.
