Thank you so much again cher Amie! So i read the link, but the main problem is that they sent me an email on may telling me that my PR was cancelled, when i tried to find out why ,an agent told me that it might be a mistake and i received after an other email saying that my application was not on the system yet and that i have to be patient....The other problem is that i never received an email of confirmation about the PR, just the receipt for payment, and after reading the link i saw that they want that.You should be eligible for the ‘OWP under TR to PR Pathway’ & can apply at 4 months before your work permit expires, which for you means RIGHT NOW before your permit expires on Dec 31, 2022. If you were eligible for TR to PR, then you are eligible for the 'OWP under TR to PR Pathway'. Read the instructions all the way through several times because some of the instructions do not logically follow what is requested online, but follow the instructions anyway because that is how they are 'routing' your application to the right area for processing.
From IRCC's website:
If you applied under the temporary resident to permanent resident (TRPR) pathway, you may be eligible to apply for an open work permit under a temporary public policy.
The policy:
