Its boundaries saw minor adjustments over the years, but always contained the communities of Taber, Warner, and Coaldale, stretching east from the City of Lethbridge and south to the Montana border.

The district became a flashpoint of controversy in 1994, when the Alberta Court of Appeal heavily criticized the new map of electoral boundaries drawn up by a committee of PC MLAs led by Bob Bogle.

The Court noted that “one of the smallest divisions in the province...was that for which [Bogle] was then the sitting member.” A new system for appointing boundaries commissions was introduced in 1995, and Taber-Warner was subsequently abolished.

The 1975 election in Taber-Warner was hotly contested, with second-time PC candidate Robert Bogle facing Social Credit leader and future Reform MP Werner Schmidt.

He would go on to serve five terms as MLA, holding the position of Minister of Utilities and Telecommunications between 1982 and 1986, and briefly of PC caucus chair and Whip before his retirement from politics in 1993.
