<blockquote>Say farewell to the old Caledonia mill, which has sat on the banks of the Grand River since 1853.Efforts to restore the last water-powered mill on the Grand River began in 1981 but have consistently been curbed, mainly because of the funding issues.
The Golden Horseshoe Antique Society, which ran the town’s annual steam show, took on the project in 1981 when the Grand River Conservation Authority threatened to tear the mill down. The latter acquired the property in 1979 with the idea of turning the site into a park.
The mill stopped grinding flour and feed in 1966. In the 19th Century, it put out more than one thousand 300-pound barrels of flour a week and shipped to Europe, Quebec and Western Canada. It operated as a feed store until 1975.

Too late to get any photos myself. This was due to be demolished and replaced by March of this year (according to the article). Not so many old mills left in Ontario.
