I am looking at this from a much different perspective. From my subjective view, once a decision is made, the process is complete (ie: you have either been approved or denied for PR), and your worries and anxiety should dissipate. Of course, there are situations that greatly inconvenience applicants that are simply waiting for the PPR in order to move forward with their lives (the majority of applicants do not have this particular issue). To qualify the above statement, I do not consider a delayed request for an applicant's passport significant if, and only if, that applicant has received notice that a decision has been made.
Notwithstanding the previous, you make a great point that I completely failed to consider while posting my comment. If one has or has not received a 'decision made' notice, and the PPR has been requested, I can only speculate that the ongoing strike would delay the passport processing. Again, you and I are making an unwarranted assumption that only Foreign Officers are able to process our passports. It may be true that there is a specialized sub-group within the Ottawa Permanent Residency office that have the full authority and training to do the same; however, we do not know this (unless you have evidence to prove me wrong).
In response to your comment regarding the long time delays in answering requests/clarification made by applicants, I can only tell you that this is normal. We are dealing with the government and delays are and have to be fully expected.
Another extremely important item to consider is this: Each time an applicant poses a question to CIC, a processing officer would be tasked to respond to his/her question. Please imagine the inner workings of any organization; this person is now forced to take your application (including all of the documents necessary to appropriately answer the applicant's question thoroughly) away from the desk and/or ordered file where it is currently residing. That applicant's application may have been inadvertently delayed by a great deal of time (of course, the time delay depends on the question intricacy and/or the motivation of the processing officer tasked in answering the applicant's question), since it was removed from the usual processing 'assembly line'. We should all be very scrupulous in deciding to write CIC regarding our ongoing application, unless there is an absolute necessity to do so. If something is wrong with an application, they will get a hold of you! Of course, common sense should prevail when the ECAS system hasn't been updated to reflect a completed medical (I would definitely consider this to be a situation that would give rise to write an email to CIC). Although, in my opinion, requesting your application notes would be a much better approach since you would leave your application alone and not inadvertently delay it (by removing it from the usual processing line).
Please keep in mind that the above are my personal opinions, assumptions, and comments. Although I have read and researched extensively about the PR process, I am not 100% on some of them.
