A bronze plaque in honour of Howard Park Methodist Church parishioners who gave their lives in the First World War was unveiled on November 6, 1921, near the north wall’s east end of the church.
In 1910, the Howard Park Methodist Church moved to a new, partially finished building located at the corner of Sunnyside Avenue and Marmaduke Avenue. In 1925, the church became Howard Park United Church. The congregation remained at this location until 1969, at which time Howard Park united with Emmanuel United Church to form Emmanuel-Howard Park United Church in the Emmanuel building at 213 Roncesvalles Avenue. Then in January 2016, it was renamed Roncesvalles United Church. It is not known what happened to the plaque.
