Early Methodists were served by ministers working a 'circuit' of communities the earliest of which west of Toronto was the Cooksville (Mississauga) branch of the (rural) Toronto circuit which began about 1845.

[1] 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.

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 (1967) then to Toronto (1997).
