Our congregation dates back to 1848 when the Presbytery of Toronto enrolled forty members and dispensed its first communion. In the same year Thomas McKee Kennedy sold an acre of land for the sum of five shillings at the northeast corner of Sheppard and Midland Avenues and a frame building was erected. In 1872 a new brick building, now known as Knox United Church, was built to replace the first structure.

After church union in 1925 those members adhering to the Presbyterian faith continued as a Presbyterian congregation. On June 22, 1926, a large number of friends and adherents gathered for the laying of the corner-stone of the new Presbyterian Church to be built on Main Street, now Sheppard Avenue, on a very desirable site purchased from R. M. Paterson. On November 14, 1926, the present church building was opened and dedicated. Due to the growth of the congregation and Sunday School, the Christian Education Building was erected adjoining the sanctuary and was dedicated on September 28, 1958.

In 1998 we celebrated 150 years of faith and witness in Agincourt when a stained glass window was dedicated in the sanctuary and a book “The Changing Scene” was published.
