Actinolite is a community on the Skootamatta River in eastern Ontario. It is in the Municipality of Tweed, in Hastings County, on Highway 37 just south of Highway 7 and north of Tweed. Greyhound express buses between Toronto and Ottawa use Actinolite's Log Cabin Restaurant as a rest stop.
When Actinolite was first founded in 1853, it was called Troy. A number of Billa Flint's sawmills were built on the Skootamatta River here. In 1859, it became Bridgewater. In 1895, it was renamed Actinolite after an asbestos-like mineral actinolite that was being extracted from open-pit mines near the town. [1]
