St. Roch National Historic Site of Canada

St. Roch was designated a national historic site of Canada because:

• she became the first ship to cross from the Pacific to the Atlantic by the North West Passage;
• she was also the first ship to complete the hazardous journey in both directions.

The Canadian-built St. Roch is valued as an excellent example of Canada’s maritime history. She navigated the Northwest Passage, arriving in Halifax in 1942, after spending two winters frozen in the ice. She was the second ship to make the Passage, and the first to conquer the journey from the Pacific to the Atlantic. In 1944, the refitted St. Roch returned to Vancouver via the more northerly, deep route of the Prince of Wales Strait in eighty-six ice-free days – the first to navigate the Northwest Passage in a single season. Retired in 1948, St. Roch was sent to Halifax via the Panama Canal in 1950, making her the first ship to circumnavigate North America.

Under the command and leadership of Sergeant Henry Larsen (1899-1964) who was first mate and captain for twenty years, the voyages of the St. Roch demonstrated Canadian sovereignty in the Arctic. She extended and maintained Canadian control over its vast northern territories as an all-purpose supply, patrol and transport vessel and governmental representative to service isolated and relatively inaccessible R.C.M.P. detachments by settling disputes and conducting a census of the Inuit. During this time the St. Roch was the only federal presence in the far north. During the Second World War the St. Roch was sent through the North West Passage to protect war industries in the north, specifically a mine in Greenland which was the sole source of cyrolite essential to the production of aluminum.

The heritage value lies in the original design and the multiple refits that were designed to deal harsh conditions and reflect the changing technologies in marine transportation over the course of her working life. The St. Roch has been restored to her appearance during her epic journeys between 1940-1944 that was a mix of original elements and subsequent refits. Additional value in her material fabric include the spare and well-considered details of her design in terms of the efficiency and economy of her living and working quarters.
