Historical expeditions

As a result of their westward explorations and their settlement of Greenland, the Vikings sailed as far north and west as Ellesmere Island, Skraeling Island and Ruin Island for hunting expeditions and trading with Inuit groups. The subsequent arrival of the Little Ice Age is thought to be one of the reasons that further European seafaring into the Northwest Passage ceased until the late 15th century.

The Spanish made numerous voyages to the northwest coast of North America during the late 18th century. Determining whether a North West Passage existed was one of the motivations for this effort.

 before passing through. The United States government, when asked by a Canadian reporter, indicated that they did not legally ask permission as they were not required to. The Canadian government issued a declaration in 1986 reaffirming Canadian rights to the waters. However, the United States refused to recognize the Canadian claim. In 1988 the governments of Canada and the U.S. signed an agreement, "Arctic Cooperation", that resolved the practical issue without solving the sovereignty questions. Under the law of the sea, ships engaged in transit passage are not permitted to engage in research. The agreement states that all US Coast Guard vessels are engaged in research, and so would require permission from the Government of Canada to pass through.

In the summer of 2000, several ships took advantage of thinning summer ice cover on the Arctic Ocean to make the crossing. It is thought that global warming is likely to open the passage for increasing periods of time, making it attractive as a major shipping route. However the passage through the Arctic Ocean would require significant investment in escort vessels and staging ports. Therefore the Canadian commercial marine transport industry does not anticipate the route as a viable alternative to the Panama Canal

, the latter part of the 20th century and the start of the 21st had seen marked shrinkage of ice cover. The extreme loss in 2007 rendered the passage "fully navigable". However, the ESA study was based only on analysis of satellite images and could in practice not confirm anything about the actual navigation of the waters of the passage. The ESA suggested the passage would be navigable "during reduced ice cover by multi-year ice pack" (namely sea ice surviving one or more summers) where previously any traverse of the route had to be undertaken during favourable seasonable climatic conditions or by specialist vessels or expeditions. The agency's report speculated that the conditions prevalent in 2007 had shown the passage may "open" sooner than expected. An expedition in May 2008 reported that the passage was not yet continuously navigable even by an icebreaker and not yet ice-free.
