Lucky! I haven't seen my husband since March
( Almost a year now) because the visa offices won't give us a visit visa to Canada since we have the strongest ties to each other and not the family back home. I hope I have at least another 2-3 months to wait and that my VO doesn't delay the processing anymore (because there are still some 2012 applicants waiting to hear from my VO for good news...this whole process can be very frustrating, but it is only my VO that goes into extreme hibernation, so don't be worried).
I didn't mean to scare you about your documents being misplaced. But as long as you have a letter saying that you are submitting the medicals and PCC for application XYZ, with sponsor name and applicant name, and UCI #, you should be fine
You will get UCI number with AoR from CIC-M, and it usually takes a month from date of submission of your application.
