From what I read in this forum, it's mean IRCC has some concern about your application. Maybe it's nothing. But try to think what there concern could be and prepare yourself if you have to prouve them wrong.This letter refers to your application for permanent residence in Canada under the Protected Persons class.
Please be advised that your application has been transferred to the Humanitarian Migration (HM) Office in Montreal for further assessment. The office may contact you for an interview or to seek additional information or clarification. That office will make a final decision on your APR and communicate to you its decision.
Should you need to submit additional information or make any further enquiries regarding your application, you may contact the HM Montreal Office in writing as follows:
