This church opened on Nov. 18, 1877 as a branch of the Scarboro Circuit of the Methodist Church of Canada to meet the religious needs of this rural community. The property was given by Mr. and Mrs. John Crawford to the "Trustees of the Mount Zion congregation", namely: "John Sewell, Peter Reesor, James Ormerod, George Pearse, James Pearse, Robert Stockdale and Thomas Barnard." Combining to form the congregation were members of the Bible Christian Church which had held services in the area for over 20 years, and adherents of the former Wesleyan Methodist Church who had no nearby place of worship. Known from its opening as Hillside Church, it continued to serve the area until church union in 1925 when the congregation became part of the Zion United Church, Markham. Both the exterior and the interior of the church remain essentially the same as they were in 1877.
