Under Canada's immigration legislation, all immigrant applications are subject to statutory requirements, including medical and background checks. These requirements must be satisfied before an applicant may be granted permanent resident status. In this context, certain background investigations are being conducted in connection with your application. As these investigations are conducted by outside agencies, we have no purview over the processing time. We are therefore unable to give an exact time frame in which we expect to conclude the verifications on this case.
For now, there is no action required on your part. Please be assured that as soon as the checks are completed the next steps in this application will be determined. Until then, we will not be able to provide any additional information on this case.
Delays in the processing of visa applications are always disappointing to all concerned, but rest assured that all efforts are being made to ensure efficient and expeditious processing of all visa applications.
We trust that this information will be of assistance.
