I know here in BC the Labour ministry has job centres called "WorkBC" that not only help with resumes and job searches, but actually have dedicated classes specifically for newcomers from Ukraine.

P.S. Welcome! We're glad to have you, and I hope everything works out without too much trouble :)

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.

FB or instagram aren't going to be useful job hunting. If you're in IT, perhaps LinkedIn would be expected, but a Github account with a commit history would probably be more useful in reality.

I wouldn't sweat it, just start applying and see what comes. Obviously an email address will be necessary. You can access internet at the library if you don't have other sources.

I've always asked friends and family for help with my résumé but a library or a community centre will definitely be able to either help or point you in the right direction. Worst case you can post again here with the personal information changed or blacked out.

Welcome to Canada! I'm sorry for how things are going there and I hope you enjoy your time here!
