Satellites are not "old tech". Satellites can have serve many different purposes, some quite advanced. Most countries pay the private sector to launch their satellites as it's cost prohibitive unless you're doing it on a constant basis.
Denmark wishes to see China join the Arctic Council as an observer. Greenland sees potential with China. And an admiral from China has made a territorial claim to the Arctic. The world sees opportunity here, and we don't have a base there yet.

It's not hard to get a cell connection but try moving data. The bandwidth sucks.
Somewhat misleading. The first link is about economic cooperation, nothing military or political involved. The second link involves Chinese intervention via an Arctic country with its consent.
The third link is more political and military in nature, but even it tries to argue its case on teh basis of a flawed interpretation of international law, which could easily be overcome.

At the end of the day though, Canada's territorial integrity won't be protected by simply having a larger military, but rather by establishing our claims in international law.
