The Holy Trinity congregation was officially organized in 1915, and in 1916 Owen L. Jull, the incumbent at St. Peter's (Sault Ste. Marie) and Tarentorus purchased the land (a Michigan blueberry patch). The first Holy Trinity Anglican Church (a white frame building) was completed in October/November 1917 with the first service being held on December 9, 1917. In 1918 the church was consecrated on Trinity Sunday with Archdeacon Gowan Gillmor ("the tramp") as incumbent.
The first parish hall was completed in 1924; it was sold in 1939. Holy Trinity separated from St. Peter's in 1928; the two were rejoined in a single parish with Christ Church (Korah Township) in 1942 under F. F. Nock. A second, adjoining church hall was completed in 1952. In 1958 the parish was reorganized and Holy Trinity was twinned with All Saints' under Bruce Fraser. In 1959 the congregation decided to build a new, larger church; the first sod was turned on August 28th. The second church was completed and dedicated December 1, 1960. In 1962, Holy Trinity became an independent, self-supporting parish with its own Rector, Donald M. Landon.
In 1986 the "Penhorwood Wing" was added on the west side of the existing church building. It was named to honour the architect and building supervisor of Holy Trinity's second church building, Russell T. Penhorwood. The wing was dedicated by Bishop Peterson on December 4, 1986.
