But she was NOT eligible for a new PR card at the time that application was made. That alone makes it, well, very DIFFERENT. That situation illuminates rather little, and more likely NOTHING, about the routine or typical timeline for PR card applications.
I grasp her situation, understand your frustrations, and am sympathetic. As I have observed before, among some rather extensive observations about several aspects of the situation, even though the initial problem was the Residency Obligation breach, and being inadmissible on the face of things, and otherwise NOT eligible to be issued a new PR card when she made the application, what you have reported about the ongoing situation suggests there is a significant likelihood some other issue is now the problem, and that the SAFE approach would be to consult with a lawyer. In any event, however, it is very much an individual case caught in its own particular processing issues and is in NO WAY relevant to general discussions about processing timelines.
By the way, unlike some advice offered in the discussion in the other thread, my suggestion to see a lawyer is NOT about pursuing Mandamus. There is enough risk lurking in her situation that it would be wise to have a lawyer review all the paperwork she submitted with the application, including a copy of the application of course, and review all the aspects of her situation and status, to figure out (as best it can be done) what has happened, what is happening, what is at stake. A GCMS records request, more in-depth than the generic request for a copy of personal GCMS records, may be needed and at the least would be a good idea.
About the only aspect of your daughter's situation that is relevant for the discussion in this thread is that it is one more reminder why the conventional wisdom is so adamant that PRs who have breached the PR RO should wait until they have been IN Canada for more than 730 days within the previous five years BEFORE making a new PR card application.
