Nice to know this, thanks. You mean IRCC tends to issue PRTD to people like me without any limit other than PR card with a lot more limit?
And, as you mentioned, it's safer if my wife goes with me (accompany) to enter Canada. We actually DOES plan to visit our daughter at UBC in May. But our home in Ontario is going to off rent in April and I have a plan to do some renovation myself. Is this a good reason to go just myself?
Re Multiple-entry (multiple-use) PR Travel Document:
As I noted, we have not seen much anecdotal reporting lately about this, but we know IRCC did begin issuing more of these a few years ago. It is not clear why some got the multiple-use PR TD while others did not. Obviously, you will not know if you get one unless and until you make an application for a PR TD.
How long it is good for, when issued, is similar to multiple-use visas: typically the PR TD will expire when the PR's passport expires or in five years, whichever happens first. That said, there have been isolated reports of multiple-use PR TDs issued for periods shorter than that (expires in less than five years and sooner than when the passport expires).
Re Travel to Canada Accompanying Spouse or Not:
Except for how it goes in a specific instance, that is on a particular occasion when you are arriving at a Canadian PoE, this is more about impression and perception, not about screening criteria, not a substantive factor.
There is a tendency in the forum to focus on particular transactions, and thus the particular situation attendant that transaction. And of course that is the context in which decisions are made. What happens, how it goes, when a PR applies for entry into Canada from abroad (which is an application made by just arriving at the PoE), or applies for a PR TD, or applies for a new PR card, and what will affect that, what will influence how that goes, is of course the main thing. And while there are many variables involved, we can readily identify some patterns. No advanced degrees in government policy necessary to recognize there is a significant difference between showing up at the PoE with a valid PR card versus arriving at a land border crossing PoE and presenting an expired PR card. Nonetheless, that is in general, and how it goes for a specific individual on a particular occasion will depend on other factors.
Other factors include the PR's history. Some of that is about screening criteria and is substantive. Big difference, for example, if the returning PR was last in Canada three plus years ago (even if presenting a valid PR card) versus the PR with a travel history more or less indicating the PR lives in Canada and travels abroad for occasional brief trips. The differences can be less stark, less obvious. Sometimes a PR's frequent international travel history points in one direction, sometimes in another. Often there is a discernible pattern, which can indicate the PR is primarily living or working abroad and visiting Canada, or it can indicate the PR is primarily living in Canada and visiting abroad. Varies from individual to individual, based on the particular individual's actual history.
But whether the PR is even examined at that level of detail varies considerably. What triggers elevated scrutiny is a huge, huge subject, a difficult subject, and even though we can identify many of the factors, we do not know others, and how this or that factor actually influences how it goes is often uncertain. Again, we recognize some patterns, some correlations, but generally cannot precisely map particular factors to definite outcomes.
Which brings this back to the other side of things, and that is the tendency to underestimate, if not overlook, the influence this or that impression, or this or that potential perception, can have. This includes the influence the PR's history can have. This is not necessarily about a direct connection but, again, about impression and perception. The rules are one thing, and they dictate the grounds for formal decision-making. Impressions and perceptions, in contrast, can steer officers in one direction or another, toward being more or less casual, or toward being more vigilant if not strict or even severe.
The long way round to addressing travel to Canada accompanying a citizen spouse versus coming here apart from, not accompanying the spouse.
Here too, there is how it goes in the course of a particular transaction, that is, upon actual arrival at a PoE. As I suggested before, for a couple traveling together, the odds are high border officials will not so much as blink let alone overtly think about verifying the accompanying PR's RO compliance (unless there is some other history or factor triggering elevated scrutiny), let alone dive into questions or details about
who-accompanied-whom going abroad. And, there is no reason to apprehend or fear the risk of such questioning even when traveling alone . . . except the threshold for what other history or factor might trigger such an examination is probably lower. But even if you encounter such questioning, being prepared to show marital relationship, spouse's citizenship, and cohabitation abroad, and if asked, being able to otherwise explain your situation, including for example that the primary reason for living in the states is the spouse's employment (assuming this is true -- fudging information is an entirely different scene), should be readily sufficient. As I noted before, your situation does NOT sound any serious
who-accompanied-whom alarms. EXCEPT . . .
Except it might . . . if there are other circumstances potentially inviting such questions. Which is where history again comes into the picture, including future history. Arriving at the Canadian border alone once or twice is not likely to raise any questions. A pattern of that, however, sooner or later might. Again, it is very, very difficult to forecast what triggers elevated scrutiny, what makes the difference between encountering a few casual questions versus being closely examined. You do not appear to be at much risk. But of course that is based on only a sketchy outline of minimal facts. These observations are mostly about being prepared for what could happen rather than what is likely to happen, about reducing risks.
