After the Nootka Convention of 1789, the pacific coast of modern-day Canada and the northern U.S. became a condominium of Spain and Great Britain.
Establishment
October 1790: In 1790, the Nootka Convention was signed between Spain and Great Britain, following a dispute over sovereignty on the Pacific coast. This agreement allowed the English to establish settlements in areas claimed by Spain but not settled by them. This marked a shift in determining sovereignty based on settlement rather than prior discovery. The Pacific coast became de facto joint English-Spanish territory.

January 1797: Russian colonization of Alaska by 1796.
January 1800: Old Sitka was founded in 1799 by Alexandr Baranov, the governor of Russian America, in Novo-Arkhangelsk (today: Sitka). The territory was under the control of the Russian-American Company, a trading company established by the Russian government to exploit the resources of Alaska.
February 1819: The Adams-Onís Treaty was signed between the United States and Spain in 1819. It established Spanish rights to Oregon, which were later acquired by the United States. The treaty was negotiated by John Quincy Adams, who was the U.S. Secretary of State at the time.
February 1819: Establishing the Oregon Country as a shared region with the United Kingdom. Oregon Country had no defined northern limit, but it can be assumed that it did not encroach much upon Russian-held lands; this map uses the later-established line at 54°40′ north for simplicity.
February 1819: The Adams-Onís Treaty was signed between the United States and Spain in 1819. It established the western boundary of the Louisiana Purchase and granted Spanish rights to Oregon to the United States. This paved the way for the eventual joint occupation of the territory by the United States and Great Britain.
