The building at 41 Mornington Street, in the City of Stratford, known as St. James' Anglican Church, is a buff brick building designed in the Decorated Gothic Revival style by architects Gundry and Langley. It was constructed between 1868 and 1870.

The aesthetic and scenic character and condition of the property as well as the exterior of the building are protected by an Ontario Heritage Trust conservation easement (1985). The property is also designated by the City of Stratford under Part IV of the Ontario Heritage Act (By-law 134-83).

Located at 41 Mornington Street, at the top of the hill, St. James' Anglican Church sits on a triangular lot and overlooks the City of Stratford. The church fronts Mornington; however, Hamilton Street runs along the west side of the church. Located near the property is the former rectory, built 1876, and now a private residence. Also located on the property is the former St. James' cemetery. Some of the area's first settlers are known to be buried here, along with a number of unknown bodies, some of which were prisoners from a, once, nearby jail. The last burial took place in 1871.

St. James' Anglican Church is associated with the settlement of Stratford. The first Anglican services in Stratford took place in one of the first buildings in the new settlement, the Shakespeare Hotel, built in 1832. Rev. William Bettridge traveled from Woodstock to Stratford to deliver services. In 1843, the parish of St. James' received its first incumbent, Rev. William Hickey. Two of the congregation's previous churches have been located on the present site. The first was a wood frame structure, built in 1840, and the second church was built in 1855. The present church was built between 1868 and 1870, designed by prominent architects Gundry and Langley. Bishop Benjamin Cronyn (b.1802, d.1871), first Bishop of the Anglican Diocese of Huron, opened the church on March 20, 1870. In 1876, the parish of St. James helped spread Anglicanism in Stratford by opening a mission church at the opposite end of town called Home Memorial. The mission was the predecessor to St. Paul's Anglican Church, which opened in a new building in 1905. St. James is also associated with parishioners Robina and Kathleen MacFarlane Lizars, who coauthored the novel Committed to His Charge: A Canadian Chronicle (1900), which described life in Stratford and St. James' Church. A donation towards a set of bells was made, in 1906, which provided incentive to build the tower, which was completed in 1909.

St. James' Anglican Church is an excellent and well preserved example of the Decorated Gothic Revival style. The church was built of Brantford 'white' brick and has a steeply pitched cedar shingle roof with dormer windows. One of the chimneys is unusually slanted in order to emerge at the peak of the roof. The facade has a tri-partite lancet window with a small rose window above. The pointed-arch double wooden entrance doors are flanked by two lancet windows. The side walls are divided into six bays separated by stepped buttresses. The first bay contains wooden double doors and the other five contain twin lancet windows, paired with an oculus window above. The pointed-arch hoods over the windows and doors, and the foil patterning in the wood tracery of the oculi are characteristic of the Decorated Gothic Revival style. The tower was constructed in two phases. The tower's first phase has one narrow lancet window on each of the west and south façades. The second phase of the tower (1909) has windows that make up a larger proportion of each elevation, and the arch hoods over the windows do not protrude from the wall, as they do elsewhere on the church. St. James' has undergone a number of additions and renovations: the addition of the parish hall (1891), the addition of the bell tower, the connection of the church and the parish hall (1913), the construction of an annex to the parish hall (1959), and the repair and re-cladding of the tower finials with copper (1998 and 2003).
