We did our soft landing in April 2018, then moved here permanently in August 2019. Oldest daughter moved here permanently in 2021 and has just realised she is short of days to make up the 730 in five years since PR started. She's about 50 days short. If those couple of months when we were all together in the UK, before she turned 19, count, then she would be OK. If not she is in trouble because she's currently in the UK for her graduation. Even if she comes back immediately and misses graduation, she will still be short.
She has been working in Canada for almost a year and is in the process of applying for grad school here. The reason she did not come to Canada in 2019 is that she had to finish university in UK.
So, I don't understand the dates etc for her or when exactly she is returning to Canada or even exactly where she is now.
But:
1) As I mentioned above, the difficult bit above is getting a
formal adjudication of whether her time with parents qualifies or not. The usual places where this might get done are when applying to renew a PR card, applying for a PRTD (because no PR card), or on appeal if reported at a border entry.
2) This does not mean all is lost. If anything, she can enter Canada on her existing PR card. Violating the residency obligation does not result in losing the PR status automatically.
In practice, when she enters, if they ask, she should just tell the truth - responding as briefly as possible. Most of the time for small amounts in excess outside of canada will just be ignored. Normal reasons like 'my studies' and 'covid' would probably be enough if it did come up.
If they ask
lots of questions, she should mention that some of the time abroad was with Canadian parents (one PR, one citizen).
Worst case (in my guess, rather unlikely, but not impossible): she'd get reported for being out of compliance and have to appeal.
Down the road, the biggest issue will be that period when she is out of compliance and the card has not been renewed - it would make travel by air difficult. In all other respects she can live in Canada as a PR while waiting to get back in compliance/receive a new Pr card. But for a UK passport holder (I presume), she'd be able to enter USA and cross a land border, so even the travel thing is maybe less severe than for some.
Note - I'm
assuming here that going forward she'll be primarily residing in Canada, at least until back in compliance. And if she ever gets warned at border, she may have to be a bit more careful.
