HMCS Onondaga

The Onondaga is a Cold War-era submarine now functioning as a floating museum in Rimouski. Its interior reveals control rooms, torpedo chambers, crew sleeping areas, and engine compartments that show how sailors lived and operated this vessel.

The vessel entered Canadian Navy service in 1965 and spent 35 years on Cold War patrols across the Atlantic. After decommissioning in 2000, it was preserved and converted into a museum documenting Canada's naval operations during that period.

The museum presents the role of submarines in Canadian naval life through displays showing how crew members lived and worked in confined spaces. Visitors can see the personal items and daily routines that reveal what service aboard felt like.

Visitors navigate the narrow vessel using audio guides in English and French that explain each section and how it functioned. The site is open from June through October, providing visitors with a defined season to plan their exploration.

Outside the hull, an interactive course lets visitors use tablets to complete simulated submarine missions and learn about vessel systems. This hands-on activity complements the on-board experience and brings technical concepts to life for all ages.
