York Factory

York Factory was a settlement and 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. The settlement was headquarters of the Hudson's Bay Company's Northern Department, from 1821 to 1873. It continued to operate as a fur trade post for over 270 years until 1957 when the company closed it down.

The complex was designated a National Historic Site of Canada in 1936. It has been owned by the Canadian government since 1968 and is now operated by Parks Canada. Aside from a summer residence for Parks Canada staff and nearby seasonal hunting camps there is currently no one living permanently at York Factory. The wooden structure at the park site dates from 1831 and is the oldest and largest wooden structure in Canada built on permafrost.

York Factory is currently located on the north bank of the Hayes River about 7 miles inland. To the north, across 'Point of Marsh' is the mouth of the Nelson River. Although the Nelson is much larger (it drains Lake Winnipeg), the Hayes is a more practical canoe route. Due to the shallow bottom sea-going ships anchored at Five Fathom Hole 7 miles from the fort and goods were transferred by smaller boats.
