I was trying to see what orbits this site would be good for, and found the answer in Wikipedia, which then led to an older SpaceQ article describing it from back when they were considering the site

Seems viable, although niche. In the past, launching companies/nations would look for a small number of launch sites that would cover all the orbits they needed. I wonder if the future is many launch sites each specializing in a few particular orbits. I also wonder what the deltaV efficiency is compared to a more equatorial site.

Also, while I would prefer that this site were being developed by a Canadian company, if they're respectful to how we do things in Canada and the local community, as far as I'm concerned they're welcome. Not that my opinion matters in this decision. Good to see a Canadian supplier getting business, though.
