Bloomington is a hamlet in York Region, Ontario, Canada, in the town of Whitchurch-Stouffville. The hamlet is centred at the intersection of Ninth Line and Bloomington Road near the eastern boundary of the town of Whitchurch–Stouffville. Neighbouring communities within Whitchurch–Stouffville include Musselman Lake to the north, Lemonville to the west, and the community of urban Stouffville to the south. The hamlet of Goodwood in the town of Uxbridge lies to the east.[1]
The first settlers arrived in the early 19th century, and were largely Quakers, Mennonites and United Empire Loyalists who had left the United States. The first postmaster, Samuel Patterson, registered the name Bloomington in 1869, likely after the city of Bloomington, Illinois.[2]
There are a few reminders of the old hamlet that remain:
Bloomington is still mostly agricultural area, but some land is being developed for housing and few commercial businesses.
