HMCS Canada Expedition 2025

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

Exploring the HMCS Canada Shipwreck

Today, the wreck of HMCS Canada (a.k.a. Queen of Nassau) lies approximately 11 kilometres (7 miles) south of Lower Matecumbe Key at a depth of 70 metres (235 feet), where it is protected by the U.S. National Oceanic and Atmospheric Administration’s Florida Keys National Marine Sanctuary. This November during the expedition, highly-skilled technical divers will capture images of the shipwreck. The expedition team will then use photogrammetry to create a detailed 3D model. The shipwreck’s model, available to all on the this website, will allow anyone to explore it virtually and enable a deeper understanding of its historical, archaeological, and ecological significance.
