The changing Arctic
I am going to guess that also means more muskeg.

It probably means that the permafrost line is moving north. A lot of permafrost ground is already technically muskeg - just frozen. The creation of muskeg/bog/peatland takes centuries.The changing Arctic

HBC might have operated York Factory (near the mouth of the Hayes River) until 1957 but steel was never laid to Port Nelson (near the mouth of the Nelson river, 18 Euclidian km north). Port Nelson never operated.That Churchill railway, in 1912 it was the next big thing. The line to Prince Rupert was almost finished. It opened in 1914. The RNWMP had already set up operations at both Churchill and York Factory adjacent to Port Nelson and esablished M Division as their Hudson Bay Division. Those ports were still going concerns up until 1957 when the HBC closed its York Factory operations.
Funny. I never knew he died on the Titanic.Prince Rupert was knee capped by the loss of Charles Hays when the Titanic sank, taking him and his capital with him. I suspect that ship going down cost the Canadian economy dearly.

Then there's the elephant in the hydrographic survey room
My latest article “Canadian Arctic Hydrography: Proceed with Alacrity” has just been published in the Canadian Naval Review (Volume 21, Number 3, 2026). With its percentage surveyed to a standard adequate for safe navigation standing at a paltry 15.8%, the waters of the Canadian Arctic are woefully inadequate for submarine operations. As Canada pursues a fleet of new submarines with particular emphasis on defence and security in the Arctic region, it is imperative that this deficiency be addressed. My article suggests dedicating significant hydrographic survey capability to the task and considers bringing the Canadian Hydrographic Service to join the Canadian Coast Guard under the umbrella of the Department of National Defence.

WWI halted construction around present day Gillam, and national restructuring of all railways except CP because of their collective insolvency delayed further construction until 1925. Sometime in the intervening years, probably a result of better surveying, they came to the realization that the mouth of the Nelson River was unsuitable as a harbour due to silting, shallowness and currents and switch to Churchill. Although further away, it had a naturally deep (ish) habour and somewhat less sailing time.Correct. But that was primarily because WW1 intervened and disrupted pre-WW1 plans based on the National Policy and membership in the British Empire Trade Zone.

If they had stayed at Port Nelson, I suspect the whole concept of a blue water port and railway would have died a natural death in a few years, simply because of the cost to maintain navigation.
