Your situation is both very unusual and
tricky. It is likely
NO ONE here can offer informed advice about what is the best approach for YOU. (No one here includes me of course.)
Most of what others have offered, above, makes sense generally. But whether that is what is the best approach for you in this unusual situation, perhaps nearly unique or at least rare situation, I doubt anyone here can reliably say.
That said, if the 44(1) Report has been set aside by the IAD (which seems to be the case, although that is not entirely clear), you are still a Permanent Resident. Which means if you show up at a Port-of-Entry on the U.S. border, you will for sure be able to enter Canada. Worst case scenario is you are again subject to inadmissibility proceedings, that is potentially subject to a 44(1) Report followed by a Removal Order, which you would have to appeal again (with good to very good odds, it appears, that would be successful).
My guess, perhaps less a guess and more my impression, is that you will NOT be subject to inadmissibility proceedings upon your arrival at the PoE. But again, the worst case scenario is that you are subject to inadmissibility proceedings, so you appeal, and the positive H&C decision already made in your favour is likely to dictate a favourable outcome before the IAD.
So, I lean in the direction suggested by @Ronnie1970 . . . if you can travel to the U.S., make the trip (the sooner the better),
take land transportation to the border, and that will get you INTO Canada. Your communications with IRCC showing your name and client identification number, in conjunction with your passport, should be sufficient for border officials to positively identify you and your PR status.
This is not to advise against making a PR TD application so you can fly directly to Canada. If you are still just 19 years old, or even 20, that alone is likely to be a big positive H&C factor even apart from this positive H&C outcome. You say that PRs "
removed from canada as a minor . . . is now widely getting rejected in H&
C PRTDs." I doubt that is broadly true, however, but rather it likely
DEPENDS on the particular circumstances in the individual case. For example, many who apply for a PR TD relying on H&C relief based on having been "
removed" as a minor were not well established in Canada, never actually being settled and living permanently in Canada, so not actually "
removed."
That is, just how positive a H&C factor there is, in cases involving PRs removed from Canada as minors, can and will vary depending on the particular individual's case. Less time in Canada, hurts. Longer since last in Canada, hurts. Longer it has been since the PR is effectively an adult (which can be before they are 21), hurts. But having been removed while a minor, and making the effort to return to Canada soon after becoming an adult, is still among the most positive H&C factors tending to support relief and being allowed to keep PR status.
All that said, in regards to making a PR TD application, I am more than a little skeptical about the efficacy of a PR TD application. The advice to apply for a PR TD, after all, is the generic, FAQ type advice IRCC would give to any PR outside Canada who does not have a valid PR card. It does not suggest, let alone assure, that a visa office will approve the application and issue a PR TD. Leading this back to the suggestion that travel to the U.S. and then to the Canadian border is perhaps the better approach . . . with the caveat that, in addition to the fact I am NO expert, it is likely NO ONE here, including me, can offer reliable advice about what is the best approach for YOU.
Notes Re How Unusual the Situation Is:
Not just recently, but for a long time IRCC (affirmed by the IAD) has made decisions terminating the PR status of minors for not being in compliance with the RO. These are cases typically in conjunction with a parent's case. Which is to suggest that your successful outcome maybe something of an anomaly itself. Not easy to verify, but it has seemed that it is better for a minor who has been outside Canada for many years to wait until they are 18 and make an independent application for H&C relief, as a PR removed while a minor, than to attempt to return to Canada before they are 18 attendant parents in breach of the RO. Additionally the timeline in your case is outside norms.
There are also some potential anomalies as well, depending on the underlying procedure. The more common scenario is that your positive decision is the result of an appeal and the IAD setting aside the 44(1) Report, a 44(1) Report prepared attendant a Port-of-Entry examination resulting in a Removal Order. It is uncommon but there can be cases in which the 44(1) Report itself remains outstanding for lengthy time periods. It is not clear from what you have shared if your positive outcome is a decision by the IAD setting aside the Report (the typical scenario where there is a positive outcome), or a long pending 44(1) Report which has finally been reviewed by an officer acting as a Minister's Delegate in your favour (not common, especially given this timeline, but possibly).
