The Alberta Agenda, the Firewall Letter, was a January 2001 open letter by seven prominent conservatives in Alberta—including Calgary School professors and Stephen Harper—addressed to then Premier of Alberta, Ralph Klein, setting out a five-point firewall to "protect Alberta" from the alleged "intrusions" by the federal government. the Alberta government to fully exercise the province's constitutional powers. The group, who called themselves the Alberta Residents League (ARL) proposed the Alberta Agenda—a "new vision" for the province, which focused on "More Alberta, less Ottawa". The letter was composed by Harper—then president of the National Citizens Coalition. Harper later served as Canada's Prime Minister for three consecutive terms—from 2006 to 2015. Signatories included three political science professors associated with the "Calgary School" as the University of Calgary—Tom Flanagan, Ted Morton, and Rainer Knopff. Other signatories included Andrew Crooks, who was serving as chair of the Canadian Taxpayers Federation under Flanagan, and Ken Boessenkool, Canadian Alliance leader Stockwell Day's former policy adviser. The letter was published in its entirety in the National Post on January 27, 2001.
