Canadian Government Ship Stanley

The Canadian Government Ship Stanley has been described as Canada's first truly effective icebreaker. She was launched in 1888, and remained in service until 1936.

On May 2, 1922, the Stanley rescued an American steamer Cairnmona, when she was disabled off the coast of Cape Breton Island.

In 1927 a scientific expedition based on the Stanley and a commercial vessel was tasked to determine the safe navigation season for vessels using the new port facilities at Churchill, Manitoba, the only port on the Arctic Ocean connected to the North American Railroad Grid.
