Statement of Significance

Description of Historic Place

The Ermatinger House National Historic Site of Canada is located in Sault Ste. Marie, Ontario. Built between 1814 and 1823 by Charles Ermatinger of the North West Company, is believed to be the oldest surviving house in northwestern Ontario. It is an classically inspired, two-storey, five bay house with a hip roof, built of stout masonry and heavy timber framing. Official recognition refers to the building on its legal lot.

Heritage Value

The Ermatinger House was designated a national historic site of Canada in 1957 because:
- its builder, Charles Oakes Ermatinger, was an active partner of the North West Company;
- it was the headquarters of Sir Garnet Wolseley in 1870 when stopping at the Soo on route to Red River;
- it became the centre of the business and social life of the whole district.

Constructed when Sault Ste. Marie was still a small fur trading post on the Upper Lakes, this fine house soon became the centre of the districts business and social life, and was noted by such visitors as Lord Selkirk, Anna Jameson, Sir John Richardson, Paul Kane and George Catlin. It was built between 1812 and 1823 by Charles Ermatinger, an independent fur trader with business and family connection in Montreal. Ermatinger in 1812 had led a party of volunteers under Captain Roberts in the capture of Michilimackinac which secured the North Country for the British and was a powerful factor in bringing about the surrender, by Hull, of Detroit in August, 1812. The Ermatinger family left Sault Ste. Marie in 1828.
The imposing house was large for its time (35 feet by 40 feet) and, with its masonry construction and classically inspired design, was an outstanding landmark in its day. A succession of occupants used the house as a mission, hotel, tavern, courthouse, post office, dance hall, tea room and apartment building. In 1965 the building was purchased by the City of Sault Ste. Marie and restored to its original appearance. It is now a House Museum.
