I believe your questions will be addressed by Canarc's management very soon, possibly within the next PR they release (a week or so?).
You might consider forwarding them directly to Canarc's IR with a call or e-mail, as Canarc's management is the only legitimate source that I would trust for a unbiased truthful answer. I would think they might tell you if the PP has closed, and if it has not yet, when they are expecting it to, but I doubt they would engage in describing why.
As to the TSX listing, it is my understanding CEO Catalin is actively working closely in cooperation with the regulators on quickly closing this issue, and that will likely be the only answer you will receive, until the issue is fully closed.
In the bigger scheme of things, I see these both more as small, short term and very surmountable issues that should have little if any influence over the longer term.
