Leaside
On this site stood "Leaside", an octagonal brick farmhouse built in 1851-54 by William Lea (1814-93), a York County councillor and magistrate, amateur poet and nature lover. In 1873, it housed the newly established post-office, Leaside Junction, and in 1884 the name Leaside was given to the C.P.R. station built nearby. In 1912, the York Land Company, which had considerable property in the area, surveyed a townsite, appropriately called Leaside. Incorporated in 1913, the Town of Leaside became part of the Borough of East York in 1967.
