Thanks!
All my documents were Canadian - diploma, work experience, etc. I didn't need to do background checks from other countries and did not have any foreign work experience/bank accounts/debt. I also have almost nonexistent travel history (Canada/home country/2 short trips outside those two). It's also for a single applicant. So it should have been easy to check, that's all I can think of.
Sorry, hopefully they will do it ASAP though.
Oh yeah that sounds like a super straight forward application, nice work! Enjoy the PR!
