Watson's Mill is Ottawa's only heritage site and is one of the few industrial grist mills still operating in North America. The Mill was built in 1860, and the village of Manotick grew up around it. It is also located on the banks of the Rideau Canal National Historic Site and UNESCO World Heritage Site, which was completed in 1832. The dam behind the Mill is part of the Rideau Canal.

   Watson’s Mill is a unique working flour mill, one of the best-preserved examples of 19th century mill architecture. The building showcases a symmetrical, unornamented stone building, the original tin plated roof in the tôle de la Canadienne or Quebec style. The limestone was quarried from the river banks, and the wood was cut locally and milled at the Long Island Sawmill.

   Inside you will find ionic columns, high baseboards, plastered walls, and the original working machinery. The turbines in the basement operate from the power of the river diverted into them. Through a series of gears this power is transferred to the upper two floors to transfer grain, remove the bran, and turn the large stones that grind grain into flour.

The restoration was done while at Gibson Timber Frames located in Perth, Ontario.
