York Factory

York Factory was a settlement and Hudson's Bay Company (HBC) factory (trading post) located on the southwestern shore of Hudson Bay in northeastern Manitoba, Canada, at the mouth of the Hayes River, approximately 200 kilometres (120 mi) south-southeast of Churchill.

York Factory was one of the first fur-trading posts established by the HBC, built in 1684 and used in that business for more than 270 years. The settlement was headquarters of the HBC's Northern Department from 1821 to 1873. The complex was designated a National Historic Site of Canada in 1936.

In 1957, the HBC closed it down. It has been owned by the Canadian government since 1968 and the site is now operated by Parks Canada. No one lives permanently at York Factory; there is a summer residence for Parks Canada staff, and some nearby seasonal hunting camps. The wooden structure at the park site dates from 1831 and is the oldest and largest wooden structure built on permafrost in Canada.
