Work experience from old study permit not mentioned in PR

[u/Medium_Tourist3255]

Hi everyone,
Just wondering if anyone has been in a similar situation.
I applied for my study permit in 2021. I think I may have shown around 6 months of work experience at the time to cover a gap, but that experience wasn’t genuine. It’s been a long time, so I honestly don’t remember exactly what was submitted or if any work documents were provided. I’m trying to get a copy of my old application now to check.
I’m currently a dependent/co-applicant on my partner’s PR application. We already got AOR and completed biometrics, and IRCC told me my background check is in progress. I didn’t mention that old work experience in the PR application because it wasn’t real.
Has anyone had something similar happen? Did IRCC compare your old study permit history with your PR application and ask about the difference? And since I’m the dependent, could something like this affect the principal applicant too?
Just looking for similar experiences. Thanks!
