As a side note, I only asked about the crossing because I had a lawyer mention in passing that some locations have more experience dealing with the expired PR process than others, so I was simply just curious - just as I would be if I was looking for a medical facility to treat a certain condition and wanting to go somewhere that has more familiarity with the condition.
Lawyers are almost always a better source of information than a forum like this. When they are providing information and advice and assistance to a PAYING client. Otherwise, well, when dealing with lawyers it can be quite difficult to get what you pay for, rarely if ever more than that . . . so, if it's free, that probably says a lot about what it is worth.
That said . . . sure, seasoned CBSA officers working at major border crossings are likely to be more fully acquainted with a broader range of less common situations. But for a PR carrying an expired PR card (or at least a copy of their CoPR) who is in RO compliance, or even a PR who might be just a little short of being in compliance but who is clearly now settled and living in Canada, who is returning to Canada after a short trip to the U.S., it should not matter. For those in RO compliance, almost certain no problem, worst case scenario (which can happen anyway) is a referral to Secondary where things will be sorted out quite easily and the PR will soon be on their way. For those cutting-it-close and falling a little short, probably the same, small risk of RO-related questions, even smaller risk of encountering RO enforcement proceedings (but of course any PR who is inadmissible has some risk of encountering inadmissibility proceedings).
The nature of such questions, which appear to be asking about which border crossings are likely to be easier, however, is not like getting reviews to compare service providers. It is more like forum shopping. More like asking about when or where it would be easier to get away with this or that. Many of those here focused on helping others, on providing useful information to aid immigrants trying to legitimately navigate the system, are not interested in spending their time assisting those trying to exploit its weaknesses.
Relying on Credit Toward RO for Days Outside Canada In Employ of Canadian Business:
I am in compliance taking into account the work exception in the law. I've had a number of days where I was out of the country working for my job, so I get to the 730 with work days out of country for a Canadian company. I'm told these are discretionary though. Without the work days, I am not at 730.
I provided more context on the work days as a means of trying to add more color that felt relevant to my question. We don't know the details of the other individual's application, but I felt this community might be able to provide guidance or anecdotal experience of a similar situation regarding the Canadian work days out of country, which, for me, is something like 50, and are an allowed exception, but still discretionary.
There are several threads in this forum specifically dealing with questions about getting Residency Obligation credit for days outside Canada in the employ of a Canadian business. TOTALLY SEPARATE question, a very different subject, than clarifying that yes, it is correct that a PR does not need a currently valid PR card to enter Canada at a Port-of-Entry on the land border with the U.S. Note, after all, even an inadmissible PR is entitled to enter Canada and will thus be allowed to enter Canada when they seek entry at a land border crossing.
The inadmissible PR might be subject to inadmissibility proceedings upon their arrival at the PoE. They will still be allowed to enter Canada, even if issued a Removal Order at the PoE.
This thread is focused on admissible PRs who are not in possession of a currently valid PR card. For entering Canada at the U.S. border, a PR does NOT need a valid PR card. Best to show the expired PR card, but a copy of their CoPR will work. A Canadian drivers' license can make things go easier. Even just their home country passport, which facilitates positively establishing their identity, and the border officials then being able to confirm the individual's PR status, in GCMS, based on their identity, will work; this might take a little longer while border officials do due diligence in verifying the traveler's identity and status, but once border officials are satisfied the traveler is a PR, permission to enter Canada will be given and the PR will be on their way.
And as noted above, while it might go more smoothly at a major border crossing where seasoned border officials are more likely well-acquainted with such situations and readily know how to handle it, which border crossing it is in particular should have very little impact on how it goes and should NOT pose any risk of being denied entry.
Back to relying on RO credit for working outside Canada . . .
For a PR who has been outside Canada more than 1095 days during the last five years, and who is relying on RO credit for days outside Canada working for a Canadian business, the relevant question, the looming question, is whether they are at risk of inadmissibility proceedings, and if so, the nature and scope of that risk.
This is a way more complicated subject. A lot of other factors can influence how much risk there is of a referral to Secondary and being questioned about RO compliance. Yes, not presenting a valid PR card increases that risk. In contrast, leaving and returning to Canada driving one's own car, a car registered to the PR, should significantly lower the risk. But there are many other factors. As
@armoured referenced, the number of days in question can have a big influence. As I have referenced, the extent to which it appears the PR is currently settled and living in Canada can significantly reduce the risk . . . and reduce the risk of the examination going beyond RO enforcement questions into inadmissibility proceedings.
No need to get tangled in all those potential tangents if you are currently settled in Canada, this is a short trip FROM Canada and RETURNING to Canada, and you are close to meeting the RO without counting any credit for days outside Canada in the employ of a Canadian business. Odds are good enough, the risk of inadmissibility proceedings low enough, probably no need to worry. With some exceptions of course.
Otherwise . . . in regards to "
. . . guidance or anecdotal experience of a similar situation regarding the Canadian work days out of country, which, for me, is something like 50, and are an allowed exception, but still discretionary . . . "
This exception is not discretionary. A PR is entitled to the credit if they meet the qualifying criteria. HOWEVER, there is more to meeting the qualifying requirements than just working for a Canadian company while abroad. The criteria are quite strictly applied. Getting this credit can be tricky. But that's a different subject. If you want to know more and better understand if you can rely on credit for days outside Canada working for an employer in Canada, and what the risks are, dig through some old topics referring to this in the topic title, and if you still have related questions either pose them in one of those threads or start your own thread.
