CP Ships was a large Canadian shipping company established in the 19th century. From the late 1880s until after World War II, the company was Canada's largest operator of Atlantic and Pacific steamships. Many immigrants travelled on CP ships from Europe to Canada. In 1914 the sinking of the Canadian Pacific steamship RMS Empress of Ireland just before World War I became largest maritime disaster in Canadian history. The company provided Canadian Merchant Navy vessels in World Wars I and II. Twelve vessels were lost due to enemy action in World War II, including the RMS Empress of Britain, which was the largest ship ever sunk by a German U-boat.
SS Princess Sophia was a steel-built passenger liner in the coastal service fleet of the Canadian Pacific Railway (CPR). Along with SS Princess Adelaide, SS Princess Alice, and SS Princess Mary, Princess Sophia was one of four similar ships built for CPR during 1910-1911.
SS Valencia was an iron-hulled passenger steamer built for the Red D Line for service between Venezuela and New York City. She was built in 1882 by William Cramp and Sons, one year after the construction of her sister ship Caracas. She was a 1,598-ton vessel, 252 feet (77 m) in length. In 1897, Valencia was deliberately attacked by the Spanish cruiser Reina Mercedes off Guantanamo Bay, Cuba. The next year, she became a coastal passenger liner on the U.S. West Coast and served periodically in the Spanish–American War as a troopship to the Philippines. Valencia was wrecked off Cape Beale, which is near Clo-oose, on the west coast of Vancouver Island, British Columbia, on 22 January 1906. As her sinking killed 100 people, some classify the wreck of Valencia as the worst maritime disaster in the "Graveyard of the Pacific", a famously treacherous area off the southwest coast of Vancouver Island.
The Grand Trunk steamship Prince Rupert and her sister ship SS Prince George served the coast of British Columbia and Alaska. Prince Rupert had a 45-year career serving northern ports from Vancouver, British Columbia, from 1910 to 1955. The ship was considered "unlucky" and suffered several incidents during her career, including two significant ones that left large portions of the vessel underwater. The ship was broken up in 1956.
SS Catala was a Canadian coastal passenger and cargo steamship built in Scotland in 1925, for service with the Union Steamship Company of British Columbia. In 1927 the ship became a total loss after stranding on reef, but was recovered and returned to service. Retired in 1958, Catala was later used as a floating hotel until wrecked on the Washington State coast in 1965.
The Alaska Steamship Company was formed on August 3, 1894. While it originally set out to ship passengers and fishing products, the Alaska Steamship Company began shipping mining equipment, dog sleds, and cattle at the outbreak of the Klondike Gold Rush of 1897. The company was purchased by the Alaska Syndicate and merged with the Northwestern Steamship Company in 1909, but retained its name, and the fleet was expanded to 18 ships. During World War II, the government took over the company's ships. When the war ended, the company struggled to compete with the new Alaska Highway for passengers and freight. It discontinued passenger service altogether in 1954 and shut down operations in 1971.
For more than 35 years, from 1923 to 1958, the Union steamship Cardena sailed the British Columbia Coast, carrying passengers, groceries, dry goods, industrial cargo, mail and sundry other supplies to the 200 or so mining, logging and fishing communities that once dotted the province's coastline during the early years of the 20th century. On her return voyage, at the peak of the summer fishing season, Cardena routinely carried thousands of cases of canned salmon to the railheads at Prince Rupert and Vancouver for shipment across Canada and around the world. And so it went for the better part of half a century; a regular and reliable marine service that made Cardena a coastal institution, remembered with affection and regard by the countless men, women and children who inhabited those tiny outports in a bygone era.
MS Italia was a cruise ship built in Italy in 1967. She sailed in the Mediterranean, Caribbean, and Pacific under various names and operators, and was scrapped in May 2012.
SS Princess Mary was a passenger vessel in the coastal service fleet of the Canadian Pacific Railway (CPR) during the first half of the 20th century.
Princess Norah was a steamship which operated in British Columbia and southeastern Alaska from 1929 to 1964. From 1955 to 1958, this ship was called Queen of the North. From 1958 to 1964, the ship was called Canadian Prince. This ship should not be confused with the later similarly named motor ferry MV Queen of the North.
Lady Alexandra was a steamship built in 1924 in Montrose, Scotland which served in British Columbia from 1924 to 1952, mostly on Howe Sound.
Princess Beatrice was a steamship built for and owned by the marine division of the Canadian Pacific Railway (CPR). The ship served from 1903 to 1928 in the coastal waters of British Columbia. The ship also operated on Puget Sound on a route from Victoria, British Columbia to Seattle, Washington. Princess Beatrice was the first ship to operate in the year-round steamship service between Seattle and Victoria that was run by CPR from 1904 to 1959. This ship should not be confused with an earlier Princess Beatrice, built in Scotland in 1874, which served on the Atlantic coast of Canada.
Princess Royal was a wooden steamship built in 1907 for the Canadian Pacific Railway Coast Service. The ship operated on the coasts of British Columbia, south east Alaska, and northern Puget Sound until 1933, when the ship was sold for scrapping.
Princess May was a steamship built in 1888 which was operated under a number of different names and owners. The ship is best known for having been involved in a grounding in 1910 which left the ship jutting completely out of the water, which became the subject of a famous shipwreck photograph.
Princess Marguerite, Princess Marguerite II, and Princess Marguerite III was a series of Canadian coastal passenger vessels that operated along the west coast of British Columbia and into Puget Sound in Washington state almost continuously from 1925 to 1999. Known locally as "the Maggie", they saw the longest service of any vessel that carried passengers and freight between Victoria, Vancouver, and Seattle. The vessels were owned and operated by a series of companies, primarily Canadian Pacific Railway Company (CPSS) and British Columbia Steamships Corporation. The first two were part of the CPR "Princess fleet," which was composed of ships having names which began with the title "Princess". These were named after Marguerite Kathleen Shaughnessy, who was not a princess but was the daughter of Baron Thomas Shaughnessy, then chairman of the board of CPSS's parent, the Canadian Pacific Railway (CPR).
Camosun was a steamship built in 1904 in Paisley, Scotland, which served in British Columbia.
The SS Princess Louise was a 331-foot steamship, named in honor of Louise, Princess Royal and Duchess of Fife, Queen Victoria's granddaughter. The ship was part of the Canadian Pacific Railway's "Princess" fleet, the coastal counterparts to CPR's "Empress" fleet of passenger liners which sailed on trans-Pacific and trans-Atlantic routes. The ships of the British Columbia Coast Steamships came to be called "pocket liners" because they offered on smaller vessels the superior class of service, splendid amenities and luxurious decor equal to great ocean liners.
The SS Admiral Sampson was a U.S.-flagged cargo and passenger steamship that served three owners between 1898 and 1914, when it was rammed by a Canadian passenger liner and sank in Puget Sound. Following its sinking off Point No Point, the Admiral Sampson has become a notable scuba diving destination for advanced recreational divers certified to use rebreathing equipment.
Several vessels have been named Prince George:
