The idea of the museum was started in 1989 by two gentlemen, Henry Goerz and Peter Washburn. 

In 1990 they made an agreement with a local group, the Stony Plain and District Exhibition Society, to occupy the unused half of their land. In 1991, with the addition of a third gentleman named Ed Mothersole, the Don Gray Barn was moved to the museum’s grounds to house the collection. The museum grounds consist of approximately 14 acres, with 8 under cultivation. The museum was open to the public in 1992 and in 1993 the Founders' Building was added to act as a large display building as well as for holding special events. In 1997 the Brightbank Church was added and the Society built an open pole shelter to display more of the machinery that had been donated. In 2000 the Baron Barn was donated along with a 1922 log cabin. This cabin was restored and became the Pioneer Tea House, opening to the public in 2003. In 2001 the Armbruster house and in 2004 the replica of the Pahal family homestead were donated.

In 2008 the Municipal District Office was donated, which is the oldest municipal building in the county, an addition was added to the Founders' Building, consisting of a workshop that later became our Archiving Room and a Resource Room for meetings. Also in 2008, the Heritage Building, a large 40ft x 96ft machinery display building was built. This building was turned into an indoor 1930s era street, called Legacy Street, in 2012. 2009 saw the addition of a museum office building and the Darimont House. In 2010 the Warden School was brought in as well as what was left of Stony Plain’s original town hall. Also in 2010, the Toby Kaziel Pavilion building was moved to the grounds and to be used as a large machinery display building of 60ft by 200ft and a restoration workshop.

In 2011, the Warden School was restored and opened to the public and the Pavilion was completed and renamed as the Myshak Building. The new restoration shop was started and framed in and was completed in 2012. The town hall proved to be beyond restoration and was dismantled, with all of the salvageable material being used in the Legacy Street exhibits and other projects. A replica of the town hall was then built and officially opened in 2016.

A trapper’s cabin was acquired in 2014 and restored in the summer of 2016. During that time a gazebo was built as well as our people mover train. The train was operational for the 2016 season, proving to be a very popular attraction, especially for our younger visitors. In 2015 a teacherage was moved on to the property and the exterior was restored in the summer of 2017. Also in 2017 was the completion of an extension to Legacy Street, the Kinsmen Interpretive Centre, which is currently a multi-use space for school groups, events and tours.

The museum collection has increased to over 10,000 artifacts ranging from common household, personal, and business artifacts, equipment & tools to large farm machinery, tractors, construction machinery, and vehicles.

From one building, the museum now consists of 23 buildings, not counting the Archiving Room and Resource Room. The Stony Plain and Parkland Pioneer Museum is dedicated to increasing the size of the collection, the displays, education opportunities and its relevance to the community. Each year a crop is planted, worked and harvested using old machinery, both mechanical and horse drawn in order to keep the old farming practices alive for the children of today. In 2007 we went through the affirmation process and became a recognized museum by the Alberta Museum Association. In 2009 we became a member of the Canadian Museum Association and in 2010 we were assessed by the Edmonton Regional Tourism Group and with the improvements made we became a Recommended Experience in 2011.  © The Pioneer Museum
