===Canada=== On June 11, 2009, the [[Canadian Radio-television and Telecommunications Commission]] (CRTC) approved a proposal by [[Pelmorex]], owners of [[The Weather Network]] and [[MétéoMédia]], to receive [[must-carry]] status for the channels, in exchange for developing a "national aggregator and distributor" of localized emergency alert messages compliant with the [[Common Alerting Protocol]]. The alert system, known as [[Alert Ready]], built on a backend known as the National Alert Aggregation and Dissemination system (NAAD), was first established in 2010, and further expanded as a result of consultation with government officials, broadcasters, and the CRTC. In August 2014, the CRTC ruled that all television stations, radio stations, and broadcast distribution undertakings had to begin mandatory carriage of local alerts relayed through NAAD by March 31, 2015.<ref name=crtc-mandate>{{cite web|title=Broadcasting Regulatory Policy CRTC 2014-444 and Broadcasting Orders CRTC 2014-445, 2014-446, 2014-447 and 2014-448|url=http://www.crtc.gc.ca/eng/archive/2014/2014-444.htm|website=CRTC|date=29 August 2014|access-date=14 April 2015}}</ref><ref name=crtc-2009-340>{{cite web|title=Broadcasting Order CRTC 2009-340|url=http://www.crtc.gc.ca/eng/archive/2009/2009-340.htm|website=CRTC|date=11 June 2009|access-date=14 April 2015}}</ref><ref name=crtc-naad>{{cite web|title=Broadcasting Decision CRTC 2011-438|date=22 July 2011|url=http://www.crtc.gc.ca/eng/archive/2011/2011-438.htm|publisher=CRTC|access-date=14 April 2015}}</ref> The province of [[Alberta]] had its own system called the [[Emergency Public Warning System]] (EPWS). The EPWS was put into place after a major tornado swept through the city of [[Edmonton]] in 1987, killing 27 and causing millions of dollars in damage. Unlike the American EAS, however, broadcast of the EPWS was not mandatory on radio and television stations. It was broadcast on the [[CKUA Radio Network]] and was televised on [[CTV Two Alberta]] and other participating stations. EPWS warnings could be initiated by municipal police and fire departments, the provincial government, county authorities, tribal government agencies, [[Environment Canada]], and the [[Royal Canadian Mounted Police]]. CKUA developed and maintained the EPWS until January 2010, when it lost a bid to modernize the system to an outside vendor (the contract had provided 15% of the station's overall budget).<ref>{{cite news |url=http://www.cbc.ca/news/canada/edmonton/contract-loss-forces-job-cuts-at-ckua-1.974606 |title=Contract loss forces job cuts at CKUA |date= January 12, 2010|work=CBC News |agency=Canadian Press |access-date= May 20, 2010}}</ref> In June 2011, an updated version of the system known as [[Alberta Emergency Alert]] was introduced, which emphasized multi-platform availability of alerts and advisories on digital platforms, such as online and through a [[mobile app]].<ref>{{Cite news|url=http://www.cbc.ca/news/canada/calgary/alberta-emergency-system-goes-digital-1.993701|title=Alberta emergency system goes digital|work=CBC News|access-date=2018-04-01|language=en-US}}</ref> Participation in AEA is now considered mandatory under the CRTC's national public alerting mandate.<ref>{{cite web|title=Public Alerting Bulletin to Last Mile Distributors|url=https://alerts.pelmorex.com/download/public/Broadcaster%20Bulletin%202015-03-27.pdf|publisher=Pelmorex|access-date=9 June 2015|archive-url=https://web.archive.org/web/20150506000827/https://alerts.pelmorex.com/download/public/Broadcaster%20Bulletin%202015-03-27.pdf|archive-date=6 May 2015|url-status=dead}}</ref>
