Year-round shipping on Hudson Bay without the need for costly icebreakers is feasible, according to a representative for Premier Wab Kinew. Amy Tuckett-McGimpsey revealed that studies examining the extension of the shipping season, a key component of the proposed Port of Churchill expansion, have shown promising outcomes. The Manitoba government is set to disclose the findings of these studies on Friday.
Arctic Gateway Group, in collaboration with shipping firm Fednav, conducted a study to determine the requirements for enabling year-round shipping at the Port of Churchill. Additionally, the provincial and federal governments commissioned a study by the Arctic Research Foundation, founded by former Blackberry chair Jim Balsillie, to assess the potential extension of the port’s operating season. While the Fednav study has been finalized, the Arctic Research Foundation study is slated for completion in March 2027, as per statements from Kinew’s spokesperson, Rebecca Widdicombe.
Kinew aims to present the details of both studies at a summit in Toronto in September, where he intends to attract international investors for the Port of Churchill expansion. The premier highlighted that the studies indicate diminishing sea ice could allow for the navigation of Hudson Bay by icebreakers costing between $50 million and $100 million, rather than the multibillion-dollar vessels historically needed.
The proposed expansion of the Port of Churchill encompasses various elements, including the reconstruction of the Hudson Bay Railway to accommodate higher payloads and enhancements to storage and loading facilities. Additionally, Arctic Gateway Group, comprising 29 First Nations and 12 remote northern Manitoba communities, is exploring options to ship commodities through Hudson Bay earlier and later in the season, utilizing icebreakers and ice-hardened tugboats.
Moreover, Kinew has floated the idea of constructing a natural gas or oil pipeline to Churchill and establishing a year-round access road to the community. Previous research conducted by consulting firm PwC in 2023 identified several immediate and cost-effective opportunities to increase cargo traffic through the port. However, the study was less conclusive about the feasibility of a substantial investment in a northern Manitoba trade corridor.
The study also highlighted the potential impacts of climate change on the Port of Churchill, suggesting that while warmer temperatures may extend the ice-free season on Hudson Bay, it could lead to challenges such as ice jams and severe storms affecting navigation. PwC warned that climate change might result in increased maintenance costs for the Hudson Bay Railway and the Port of Churchill due to permafrost thawing.
Residents of Northern Manitoba expressed support for modest port expansions but raised concerns about larger industrial developments impacting the environment and the town’s ecotourism status. There was significant opposition to plans involving the transportation of oil through the Hudson Bay Railway or the Port of Churchill, citing potential negative effects on the environment and local communities.
Arctic Gateway CEO Chris Avery noted that the 2023 PwC report laid the groundwork for building a more diverse and resilient business at the port. The federal government designated the Port of Churchill expansion as “nationally significant infrastructure” in 2025 but did not include it in the list of major national projects approved for progression.
