York Mills
The Village of York Mills grew up around three mill sites on the west branch of the Don River about 10 km north of Toronto. From the opening of Samuel Heron's Mill in 1804 until 1926 when George Pratt's operation closed, the sounds and aromas of flour-mills, cider-mills and saw-mills filled the valley. In 1870 the Village of York Mills had a population of 100.
James Hogg owned property in the vicinity from 1824. After the Hogg brothers began to develop it in the 1850'S the area was also known as Hogg's Hollow.
