By 1850, after the Union of The Canadas, Etobicoke was formally recognised as a Township. The Great Western Railway (originally chartered as the Toronto & Hamilton Railway) was built through the southern part of the Township. The first Mimico railway station opened in 1855, just north of the tracks beside Christ Church on Church St. (now Royal York Rd.). A plan of subdivision was commissioned with side-streets for the 'Town of Mimico'. Mimico was advertised as being '8 minutes' from Toronto (by train), then bordered by Dufferin St. In 1858, a Mimico post office had been opened just south of the Railway Station on Church St. (Royal York Rd.) where St. Leo's Church is today and in 1863, the Wesley Methodist Church was established.
