The Windmill Theatre Players Society was registered as a non-profit society in 1974, after a small group of dedicated people decided amateur theatre would be a good fit for High River. The "society" title is rarely used as the group is generally referred to as Windmill or WTP. Though no one can remember who first drew it, the official logo was an artist's interpretation of the Windmill sculpture located in High River's Pioneer Square.

Windmill presents two major productions a year usually a play in the spring and a musical in the fall. Many of the members also participate in the yearly regional one-act play festival held in February or March.

Membership isn't limited to High River residents but includes people from Calgary, Nanton, Okotoks, Claresholm, Stavely and Vulcan. A total of almost 900 people have been involved in a variety of ways, in the presenting of shows in the past. And many thousands have enjoyed these shows as patrons.

Over the past 42 years Windmill has presented more than 80 major productions. Well known Broadway musicals such as The Sound of Music, The Music Man, Fiddler on the Roof, Hello Dolly, Mame and Oklahoma have been performed. One of the most successful, and the one that had the most performers on stage (69!) was Joseph and the Amazing Technicolor Dreamcoat. Well known plays such as The Mousetrap, The Odd Couple, Steel Magnolias and Arsenic and Old Lace have also been performed. The group has also produced several plays for and with children. Windmill works very hard to make each production as polished as possible. The actors, directors and behind-the-scenes people put in hundreds of hours rehearsing, sewing, building sets, selling tickets, coordinating the catering and decorations, and doing numerous other tasks to ensure the best show possible for our audiences.

Part of Windmill's mandate is to provide opportunities for its members and other members of the community to further their education in drama. Since 1988 the group has sponsored a Drama Scholarship Foothills Composite/Alberta High School of Fine Arts, and another scholarship was initiated at Highwood High School in 2001. Windmill also administers the Gordon Scott Memorial Scholarship for the Alberta Weekly Newspaper Association, in memory of Windmill member and friend Gordon Scott who passed away in 2000. Over the years funds have also been provided to well over 100 students and adults to attend summer drama programs. Funds for these scholarships and funding opportunities are realized through a gift draw program held for the duration of each major production, as well as monies realized through working at casinos.
