Founded in 1798, Hawkesbury was named after the Right Honourable
Charles Jenkinson, Baron Hawkesbury.
Thomas Mears and
David Pattee, two Americans, entered into a partnership in 1805, in order to harness the power of the lower Ottawa River and built the first
sawmill on the
Upper Canada side of the river. The town of Hawkesbury developed around this mill. Mears also built the Union, the Ottawa River's first steamer. Demand for timber during the
Napoleonic Wars created a boom. The mill complex continued to grow for at least the next half century, and by 1870 it included 145 different saws and created over 35 million board feet of lumber per year. Timber and pulp-and-paper industries have been supplanted by textiles, synthetic fibres, metal extrusions, steel, glass and plastics. Hawkesbury has also become the business and service centre of the
United Counties of Prescott and Russell. The
Grenville Canal on the Quebec side of the Ottawa River opposite Hawkesbury was an important link in the river's transportation system. Part of Hawkesbury was submerged by the
Carillon Hydro-Québec dam built between 1950 and 1962, which called for the demolition of over 300 houses in and around Hawkesbury. New developments today are happening due to baby boomers from Ottawa, Montreal and area purchasing some of the many new condos in town. ==Demographics==
