You can try applying. Nothing stopping you from doing that. I assume you only had a one year PGWP and this is why you can't get the 1 year of work experience to qualify for CEC.
IMO you need more to make a strong H&C case and as said before, that case will be weakened of you leave Canada. But again, ultimately your decision.
Not really, I had enough time on my permit.
Without getting too specific (due to privacy concerns), my rights were violated by a company. And if I was put through a fair process, I would probably would have been eligible for CEC.
I'm just having a hard time understanding what is the basis on which PR is granted in H&C. I've learnt that the danger-to-life scenario is only meant for asyulm seekers.
So how do they decide whether to grant PR in H&C? Is it granted in situations where the applicant has a dependency relationship to Canada (Eg: They have a child in Canada, or there is a specific healthcare service they need which is only available in Canada)? I don't have any such dependency. My argument is more along the lines of "Having worked hard to build a life here and being put through an unfair process".
