That sounds like something to consider; however, a TRV sounds very limited, i.e. only residence rights and nothing more. And it sounds like as it is outland application (already submitted), would that mean requiring leaving Canada to home country at some point (otherwise, what's the point of outland, if you know what I mean).
Thanks for the tip - we will keep an open mind and see how things progress.
Yes, a temporary residence visa is limited. Not "very" limited, but yes, it's not the same as PR, ability to work being the most obvious and salient difference for many.
Lots of people apply as outland because they are outside Canada when applying and then end up in Canada during the processing period; some even apply outland although they are already in Canada (see below). It seems for such cases, it's not at all unusual to receive the passport request/landing documents in Canada (without returning). The one thing that may require returning to home country is an interview if required - but it seems that the majority (vast majority? I don't know) do not ever have interviews. On top of that, it seems right now that IRCC is not doing in-person interviews at all due to covid.
What's the point of outland if already in Canada or having a visa? Various reasons, some don't have a visa already, want to get application in quickly; some need to travel quite a lot and inland inconvenient (for various reasons); some (somewhat like your case) plan to move back to Canada with Canadian sponsor abroad but want to secure employment or have children finish school or other issues first.
(I believe it used to be that outland applications were quicker to process than inland, but not clear that is still true, and probably irrelevant during covid)
Still suggest you consider applying for trv for spouse, if approved, you have more options.
