On July 20, 2019, the City of Toronto and Botanicus Art Ensemble celebrated the re-opening of MacGregor Fieldhouse.

Originally constructed in 1934, the role and function of the Fieldhouse has evolved alongside the growth and evolution of the surrounding park and community. The revitalization was initiated by Botanicus Art Ensemble (BAE) who commissioned DTAH to conduct a Feasibility Study in 2016 to investigate how the building could be renovated, expanded and made more energy efficient in order to transform it into a year-round community hub, supporting park use and community programming. The revitalized Fieldhouse has been expanded and now includes a heating system, new warming kitchen, renovated and new washrooms, and more.
