I emigrated to Canada. I met a number of other immigrants there with professional qualifications and experience. None of them were working in their profession. One, a vet, out of desperation, started to restudy his profession, from scratch, in Canada or order to restart his career there. Higher education in Canada is expensive but that was the only way he could find to do it and that'll leave him saddled with a huge debt by the time he graduates. So many of the immigrants I met couldn't afford to re-study what they already knew. I met an engineer who was driving for Uber. I met a dental hygienist who was unemployed. I met a lighting engineer/designer who couldn't find work.My aunt emigrated to Canada many years ago too. She was a highly qualified and experienced paediatric theatre nurse with the UK's NHS (think near surgeon-level training). She had to re-study too.
Additionally, in the 2010s,
Canada had a 7-year backlog of applications for work visas, i.e.
emigrating to Canada for a guaranteed professional job. They decided
that after 7 years, most applicants' circumstances had probably changed
so much that the applications we no longer valid... so they cancelled
them and made everyone re-apply.
There's a joke in Toronto that your taxi driver is probably more highly qualified than you. What a waste of talent and maybe that's why so many countries have skilled labour shortages despite having high levels of immigration?
Finally, when the COVID-19 confinement hit in 2020 and students had to stay at home, you'd think educational institutions would need more elearning and Online & Distance Education (ODE) specialists, right? No. They started firing those people instead so that inexperienced tutors and lecturers had to perform the rapid "pivot" to online. We now have hundreds of "experts" in ODE who think it's simply uploading reading materials and giving video tutorials on Zoom.
I no longer live in Canada. /end of rant
