The Canadian Pacific River Lake and River Service, also known as the British Columbia Lake and River Service, was a division of Canadian Pacific Railway (CPR) which began operating passenger and cargo shipping routes along British Columbia's inland waters during the late 19th century.

SS Okanagan was a steamship owned and operated by the Canadian Pacific Railway Lake and River Service. The vessel was constructed in 1906 at Okanagan Landing and launched in 1907, becoming Okanagan Lake's second steamship. She linked the transportation hubs at both the north and south ends of Okanagan Lake (Vernon and Penticton, respectively, aiding the development of interior British Columbia with other steamships of the 1900s. The ship was retired in 1934 and sold for scrap and spare parts. Only the Stern Saloon, a room in the back of the upper deck, remains. It was moved to the SS Sicamous Heritage Park in Penticton in 2002, to undergo restoration work.
