It has been a total shitshow. I started the process in June of 2022, eventually the team I was moving to got bored of waiting for the work permit in March 2023.
Factoring out the (ridiculous) 3 months it took for the relocation agency to prepare and submit my work permit application, it was six months of waiting with no feedback at all from the IRCC about where the process is stuck. All inquiries went unanswered.
Once I lost the position, I emailed the local Canadian embassy to let them know my thoughts, I was (expectedly) greeted back with an automated email saying that emails about immigration will not be looked at.
All in all, the processes in Canada are very immature and if you value predictability and stability in your life, do not attempt to get a job there.
