Let me share last response from VO
Background checks or further investigation are necessary in relation with the processing of this application. The Immigration and Refugee Protection Act requires that each person applying for a visa to Canada be screened in many different ways, including health, security and criminality. Often, delays in the processing of an application are out of our control as some processing steps require coordination with external authorities.
Our office will contact applicant and sponsor as soon as all verifications are completed, or as soon as more information, documents or an interview are required.
We trust this information is helpful.
