Port of Churchill, Seaport in Manitoba, Canada

The Port of Churchill is a deep-water port on Hudson Bay with four berths for Panamax-size vessels, a 140,000-tonne grain elevator that unloads 100 railcars a day and loads 1,200 tonnes per hour, and cranes of 100 tonnes. A steel and concrete conveyor gallery on a braced steel trestle runs above the water from a pale grey concrete silo complex.

The port was built by the Government of Canada in the late 1920s and shipped its first grain in 1931, after a six-year project to link Hudson Bay by rail. The British freighter Pennyworth brought the first import cargo in 1932. The federal government sold the port to OmniTRAX in 1997 for $10; after a 2016 shutdown, the Arctic Gateway Group bought port and railway in 2018, and community and Indigenous partners took full ownership in 2021.

The port's ownership passed to OneNorth in 2021, a consortium of community and Indigenous partners, after AGT Food and Ingredients and Fairfax Financial transferred their shares in Arctic Gateway. The Hudson Bay Railway shares the same parent company, and its repair in 2018 lowered the cost of goods in Churchill.

The port is icebound for most of the year and open only from late July to early November; in 2010 the season ran from 28 July to 2 November. It is a compulsory pilotage area, with pilots supplied by the Great Lakes Pilotage Authority. No road reaches Churchill, so all overland goods arrive by rail on the Hudson Bay Railway.

The port was sold to OmniTRAX in 1997 for $10, and in 2021 it passed into full community and Indigenous ownership through OneNorth. Its grain elevator holds 140,000 tonnes and can load 1,200 tonnes per hour.
