I have received notification from IRCC. I didnot include my wife as co-signer for sponsoring my parents because I have met myself the income requirement. But I received a letter mentioning "Potential Co-signer/Clarification of Principal Applicant and Dependant: It appears that you may be using a Co-signer on the application. A Co-signer can be a spouse or common-law partner of the Sponsor. Please provide a written explanation as to whether or not you are using a Co-signer." I checked the original application and still wondering what might have caused this understanding. Is it expected to use co-signer for parent/grandparents sponsorship ?
Check the form 5768 again:
on Page 1, point 4 - did you put all "0"
on Page 3, Point 11
Check the from 5406 :
did you mention dependant information even if they are in Canada ?
