The initial boundary was set by King George III. That boundary is (more or less) still in effect.
The treaty ending the war of 1812 further clarified the border as far west as the Great Lakes.
A boundary commission with international mediators set the border from Lake of the Woods to Puget Sound at 49 degrees N. Additional mediation clarified the border and divided the San Juan Islands and ensured that all portions of Vancouver Island and its close neighbors would be Canadian.
The border between Alaska and Canada was moved southward along the coast from about 1898 until about 1905, when it reached its present limit.
The Oregon Treaty split the disputed Oregon Country between the United States and the United Kingdom. The treaty split the territory along the 49th parallel and even extended past Oregon Country into already established American/British lands. For example, far northern parts of the unorganized portion of the former Louisiana Territory were ceded from the US to the UK. The 49th parallel became the recognized US-British Canada border from the west coast to Minnesota.
Some blood, mostly treaty, and a little indifference.

Their was altogether two treaties that established the border between the United States and Canada the first was the Treaty of Paris of 1783 which settled the basic border, then the Webster- Ashburton Treaty of 1842 that settled the boundary between Maine and Canada, in 1844 the land dispute of the Oregon Territory was settled with the United Kingdom, Canada being a part of it at the time which established the present border between the state of Washington and Canada. Then the last time it was altered was in 1903 with a tribunal involving the United Kingdom, Canada and the United States, which settled the border between Canada and Alaska. That was the last time the border between the United States and Canada ever changed.
