Early Methodists were served by ministers working a 'circuit' of communities the earliest of which west of Toronto was the Cooksville branch of the Toronto circuit which began about 1845. Five years later in 1850, with the creation of Etobicoke Township a Mimico branch of the Cooksville circuit was opened which quickly built a church in the original Postal Village of Mimico in central Etobicoke and identified itself as a Wesleyan Congregation. By 1858 with the building of the railway through today's Mimico and the establishment of a Mimico Station and Post Office with a subdivision plan for a Town of Mimico, a Mimico Branch of Etobicoke central Wesley Church was established using the old Mimico Schoolhouse at Church St across from Mimico Ave. In 1862 the Mimico Branch of the Wesleyan Methodist Church purchased property across the street from the old Mimico Schoolhouse on Church St across from Drummond where a church was built by 1864 establishing Mimico's Wesleyan Methodist Church. Although the 1850s subdivision plan for Mimico had failed, the postal village remaining a rural area, in 1890 a new plan was prepared which eventually led to Mimico becoming a Town and in 1890 the Methodist Church built a Manse on Mimico Ave on the south side just east of Wheatfield. Of the early Methodists in Mimico the main families were:
The Hendrys
The Englishes
The Gaulds This family also intermarried with the Davidsons, the family of the developer of the Humber Bay neighbourhood just east of Mimico.
Church Union
The united congregation used the new church built by the former Methodist congregation on Mimico Avenue at Station Road on the west side in the heart of Mimico. Mimico Town Council, which had been meeting in the Mimico Carnegie Library, purchased the old Methodist Church to be the Town Hall while the old Methodist Manse on Queens Ave at Mimico became Hogle's Funeral Home. The first term of union between the two former parishes was for a dual pastorate for the first year and then the election of a new pastor. When the year had ended, one of the resigning pastors, Rev. Fingald, was still the preferred choice for united pastor among the majority of the congregation creating some friction. Those Presbyterians who wished to remain outside the union refounded the Mimico Presbyterian Church and were permitted to have the old Presbyterian Church building at Mimico Ave and Church St.
After Union
Quickly following the union, Mimico was badly hit by the Great Depression and, like the other churches in Mimico and the Town of Mimico itself, the Wesley Mimico United Church found itself deeply in debt. The congregation celebrated the centennial of the former Methodist church in 1964 with the publication of a parish history which also included a history of the Presbyterian church. Wesley Mimico United Church has been faced with great challenges in keeping the church alive as the demographics in Mimico have greatly changed since the town was annexed first to Etobicoke then to Toronto.
