I submitted a case specific enquiry (common law stat declaration) about 10 days ago but I am not going to worry too much...
I submitted my semi-"upfront" medical back in May and I received an email 11 days later saying it has been attached to the file. But it took the officer another 20 days to send me any emails/request...so I won't get bothered with whether it took them CIC 10 or 15 days to attach the document i submitted to my file
FYI, the call centre is the one handling the case specific enquiry. On the GCMS note I received, it is clear that an agent in the call centre added my medical to my file...so...ironically the more you (and all people collectively) call the call centre the less resources CIC will have to process the case specific enquiry. And frankly I don't understand why people panic when it took CIC 13 days instead of 10 days to process the enquiry.
and I am not sure whether it's just luck or because I was talking soft and polite, I called the call centre the day after I submitted the semi-upfront medical through case specific enquiry because I wasn't sure I did it right, the agent was kind enough to look into my file and my case specific enquiry and then ensured me that they have all they want from me.
My guess is that because they have dramatically sped up stage 1 approval (sponsor approval), many requests for documents (meds or CSQ or other things) were probably sent out and the call centre is handling more submission than before. It doesn't help with Mar-Aug 2015 applicants submitting enquiries and call them either I guess.
As for the Mar-Aug 2015 applicants, it does seem unfair that they are being processed slower than even 2016 applicants. If you have been following this thread daily as I did, you will probably understand what has happened: the processing centre Vegreville (CPC-V) used to handle both study/work permits PLUS family class PR application, and then in 2014 CIC decided to transfer all family class applications to CPC-M for faster processing. I guess CPC-M got slowed down by the wave of refugee applications and with the promise of reuniting families made by Trudeau, they decided to ship back a batch of applications to CPC-V and the CPC-M therefore skipped to September applications (see some of the posts from about 2 or 3 weeks ago about mentioning their files being transferred to CIC-V). I guess they were hoping CPC-V and CPC-M would process applications simultaneously...which theoretically should double the processing speed. But it seems it took CPC-V a long time to get back to it's old job and is slow in processing applications (it's not like Mar-Aug applications don't get processed, but just slow...)
I am not sure whether understanding the situation will make Mar-Aug applicants feel better...nevertheless that's what I think is happening based on what I read here...
