Hello guys. Please I need your assistance.. I feel that i am totally lost ! and need your advice pls.
I am the sponsor in Montreal  sponsoring my wife outside Canada - no children . We submitted the file on 28 March 2017, we got the file number on April 10th.  We linked the application to an online account GCKEY on 11th of April. I received the e-mail for eligibility of being a sponsor on 18th of April , in this e-mail they said that " 
A request has or will be sent directly to the principal applicant with instructions outlining the requirements for submission of the Schedule A to CPC-Mississauga. If your principal applicant or their representative has not yet received this request, or an invitation to link their application to My CIC, it will be sent in the next 5 business days. Your PA or their representative should also check their junk mail in the email account provided at the time of application submission "
When we go checking on the online account GCKEY it says no documents required !
When we check on the IRCC online service it says " 
We sent you correspondence on April 12, 2017. If you have not yet provided the information or the requested documents, please do so as soon as possible." -- 
WE NEVER GOT ANY CORRESPONDANCES FROM THEM ON THIS DATE !
Now i have 3 questions:-
1-    We never received any request to submit Schedule A yet !. nothing on the online account  nor on the E-mail . How can I submit the schedule  A eIMM5669 Dec 2016 to them , and is it harmon her file if we submitted the schedule A and police certificate without any initiation from their part to submit them ?
2-    My wife is the PA she typed her name "keyboard " on the application IMM 5669 , and for sure there is no actual handwriting signature . is it normal ? or she has to make all that hassles of printing signing and scanning again ?
3-    When should she submit the police certificate" criminal record certificate" ? should it be submitted with the schedule A , or they will ask us to submit it ?
Please guys Help me
