Latest News About Sous-Marin Onondaga

Here’s what I can tell you about the latest news on the Onondaga submarine.

• Recent developments at Pointe-au-Père (Rimouski, Quebec): In early 2025–2026, there were ongoing and concluded works to raise the Onondaga and place it on new concrete supports to better protect the hull from tides and corrosion. Public updates indicate the project progressed through design, mobilization, and construction phases with the goal of fully stabilizing and relocating the submarine out of direct contact with seawater. The site and local press reported the work was planned to run through spring 2025 and beyond, with final stabilization and safety testing following. This represents a long-term preservation effort to maintain public access and interpretive viewing of the submarine’s components such as the propeller, rudder, and hydroplanes.

• Official site and museum communications: The Site historique maritime de la Pointe-au-Père and the Onondaga project pages have frequently updated timelines, contractor call-outs, and renderings showing how the mast and hull will be supported on new pilings, and how visitors will gain closer access to interior features post-restoration. They have also highlighted that the submarine will be elevated above the waterline to better withstand environmental exposure and to extend its display life. Expect occasional updates as contracts are awarded and construction milestones occur. [Sources: onondaga.ca project pages; site communications]

• Context and background: The Onondaga is a historically significant Canadian submarine that operated from the late 1960s through the 2000s and has been a public exhibit since 2008 at Pointe-au-Père. News coverage has focused on maintenance and upgrade programs that periodically update its internal systems and external exhibit conditions, with preservation work intensifying around 2024–2026 to ensure long-term protection.

Illustration (example of what the preservation work looks like):

• The submarine is temporarily elevated and restaged on reinforced concrete supports, with access platforms arranged to allow interpretive views of the hull, screws, rudder, and hydroplanes, while environmental protections are applied to minimize saltwater exposure.
