CS jobs in UK vs Canada

Hello, I’m in a bit of a weird position rn. I am a EU citizen currently studying at a U.S. uni but since Trump implemented the $100k cost for H1B visas I’m pretty sure I’m getting a job here after graduation, so I was wondering about salaries, how easy it is to get a job and the type of work available (so like is it mainly fintech, ai, B2B, routine maintenance in traditional industries, etc) and the VC scene in each of these markets.

I’d also be very interested in knowing how feasible it would be to graduate from my current uni and then go to work to one of the places I’m considering.
