Churchill, Manitoba could one day become a year-round port, according to three new studies released on August 21, 2026 by Arctic Gateway Group, the Province of Manitoba, and the federal government. The research found that modern ice-capable vessels can already navigate the shipping corridor through Hudson Bay for much longer than in the past, including year-round.
The studies were conducted by Fednav Limited, the University of Manitoba, and the Arctic Research Foundation. Funding came from the Manitoba and federal governments, as well as Arctic Gateway Group, which is owned by 41 Indigenous and northern communities. Researchers found the ice-free season has grown by about one month since the 1980s, and every half-degree of warming adds roughly two more weeks.
Icebreakers capable of keeping the route open all year would cost between $100 million and $410 million, far less than the billions previously estimated. Specially designed bulk carriers costing $60 to $70 million could operate for nine to ten months annually under most conditions.
Year-round shipping is not starting immediately. Environmental review, wildlife impact assessments, consultation with Indigenous Rights Holders and northern communities, regulatory approvals, and test voyages are still needed. Arctic Gateway Group said future operations must respect the rights holders, communities, wildlife, and environment of Hudson Bay and Hudson Strait.
The port has already seen renewed federal investment, with the Government of Canada committing $175 million over five years for the Hudson Bay Railway and port expansion. Manitoba Premier Wab Kinew has also proposed a liquefied natural gas terminal in the range of $70 to $80 billion, which would depend on reliable year-round access.
