I'm a hiring manager.
Most employers will do a quick social media snoop of applicants they are interested in, but FB and instagram are not important if you don't have them. Don't feel pressured to go back to those cesspools. Many managers (not me, but it feels like most others) like to look at a LinkedIn profile, but it's probably not a very big deal since you won't have any Canadian connections yet.
Libraries are a great resource like phanto mentioned, and would be a good place to ask for help with resumes as well.
Roughly where in Canada are you moving? There are a lot of places with big Ukrainian communities.
So I think there is a bit of unfortunate wording and lack of context in this article.
the "Shouldn't exist" quote doesn't seem to be attributed to any scientist or fisherman, and I suspect is an editorial comment from someone who associates coral with the tropics.
Have a look at species like Paragorgia arborea or the Primnoisis corals, which are both common in BC waters, and even in Alaska. Much further north.
Even in the article they indicate that the threats to these species in our waters are increasing temperatures and interactions with fishing gear, because they are cold-water, low-light corals.
Lessons of the day:
Cold-water, deep sea corals exist.
They aren't here because of global warming, but they could be threatened by it.
Because of where they are, they are poorly understood and reefs of them are still being discovered.
