Studies show year-round shipping potential from Manitoba’s Port of Churchill

New studies suggest that climate change and ice-strengthened ships could extend the shipping season at the Port of Churchill, Manitoba, by several months. According to the University of Manitoba, Arctic Research Foundation, and Canada’s largest international dry bulk shipping company, Fednav, open-water ships could travel through the port for up to 10 months per year by 2100. Currently, the navigable period at the port lasts for about four months, between mid-July and October.

Premier Wab Kinew believes that the port could become a year-round port with current technology and cheaper ice-strengthened ships, which are more affordable than icebreakers. This longer shipping season would bring more economic opportunities to the region. Fednav recommends using Polar Class 4 vessels, which could cost up to $130 million for new construction and up to $85 million for used vessels. Operating costs would range from $10 million to $14 million.

However, the studies also raise concerns about unpredictable sea ice conditions and tricky navigation to the port. The approach to the port involves navigating a shallow shoal and narrow channel with several sharp turns, which may require only open water or minimal ice conditions. Ice cover in the Hudson Bay and Hudson Strait is highly dynamic, influenced by wind, currents, and ice circulation, making it a greater operational challenge than ice thickness alone.

While the potential economic benefits are significant, there are concerns about the environmental impact of shipping through the port. James Wilt, policy manager of Climate Action Team Manitoba, highlights underwater noise, spills, and effects on marine animals as potential issues. The provincial government is considering the purchase of suitable vessels and exploring expansion plans, including an all-weather road, upgraded rail line, and new energy corridor.
