Very well said, the Canada-Alaska boundary dispute alongside the complete withdrawn of the Royal Navy from both Halifax and Esquimalt was seen as a major issue. Canada was effectively left defenseless in regards to stationed warships to directly combat enemy vessels, they took over the questionably useful battery of coastal defense guns spread around vital points however, they were not so valuable against raiders or warships who declined to come into range. Canada's defense basically balanced on the lynchpin of the Royal Navy being able to run over at the drop of a hat and defend them, in hindsight it's rather amusing how shoddy of a plan that is even with the Royal Navy being the largest naval power on the planet at that point.In that sense that Canada-Alaska boundary dispute of 1903 was an element in awakening a realization that the UK held it's own interests as paramount and was quite willing to throw Canada under the bus if it advanced it's interests elsewhere. It was a main root cause in Laurier's determination to have a more independent Canada. In OTL it took until after WW1 to come to fruition but in TTL it may push the navies cause a bit more.
