I believe there is good cause for you to be optimistic:
- IRCC has set completing the 2021 TR2PR Pathway as a top priority for this year.
- With an application date of June 3, 2021, you are in the 'sweet spot' for applications that are being processed right now (along with the last of the very large group of IG Stream applicants from May6/7).
- Don't let the lack of transparency get you down (though I know it's hard), things are moving behind the scenes based on the compilation of information people have posted on this forum. The processing of various TR2PR steps have been very irregular lately (perhaps because they have been trying to batch/automate certain steps for more speed), for example, one person was recently asked for 2 ADR's (which should have slowed down their processing for document reviews and been done long before their Background Check was even started or completed) but they still got PR a week later. So, only being asked for Biometrics now can mean something or nothing. My OWP under TR to PR was approved on a Friday, Jan 20. The call centre agent told me on Monday, Jan 23, that my Criminality had not yet been passed, but the next morning I received a ghost update and my PR email. Even today (over 2.5 weeks later) my account says that Eligibility, Background & Final Decision are still in process.
- You can work under 'maintained' status (formerly called 'implied' status). Not all employers will accept this (2 of mine did) but if you have a copy of your expired work permit, confirmation of submission of your new work permit application, and a print-out of the definition of 'maintained status' straight from IRCC's website, you can show them if they ask. This may not work if your last/expired/maintained work permit restricted you to a certain employer but it should work if it was an Open work permit.
Keep as posted on your progress & best wishes!
