HMCS Canada Expedition 2025

Bringing to life Canada’s first purpose-built warship through deepwater exploration

Honoring the Legacy of HMCS Canada: An Archaeological and Marine Sciences Expedition

In commemoration of the 115th anniversary of the Royal Canadian Navy (RCN), the HMCS Canada Expedition seeks to highlight Canada’s first purpose-built warship, His Majesty’s Canadian Ship (HMCS) Canada, through advanced marine archaeological and scientific research. The project aims to preserve Canada’s naval legacy while contributing to marine science and conservation efforts.

Launched in 1904 as Canadian Government Ship (CGS) Canada, it successfully enforced Canada’s fisheries laws and trained Canadian naval personnel for over a decade. As the First World War threatened, it was transferred to the RCN to become its second flagship. The RCN paid off HMCS Canada after the war and sold it into commercial service. An American steamship line bought it to connect Florida and the Bahamas, renaming it Queen of Nassau. Ultimately, the steamer sank off the Florida Keys in 1926.

Bring HMCS Canada Back to Life

Today, the wreck of HMCS Canada—later known as Queen of Nassau—rests 11 kilometres (7 miles) south of Lower Matecumbe Key, Florida, at a depth of 70 metres (235 feet). It lies protected within the U.S. National Oceanic and Atmospheric Administration’s (NOAA) Florida Keys National Marine Sanctuary.

This November, a team of Canadian technical divers will document the site for the first time using cutting-edge 3D photogrammetry. Their work will generate an ultra-detailed digital model of the shipwreck, revealing how Canada appears nearly a century after sinking.

The model will be shared through this website, allowing Canadians and the world to virtually explore this long-overlooked warship. It will enrich public understanding of her historical, archaeological, and ecological significance—bringing HMCS Canada to life in a way never before possible.

All results will be made freely available to museums, scientific institutions, universities, schools, media, and the public—honouring the service and sacrifice of those who have served in the Royal Canadian Navy.

This important mission has been officially recognized as a Royal Canadian Geographical Society Flag Expedition—one of the Society’s highest honours.
