It is a standard reply Warsaw sends to people in response to their inquiries. This is the exact text:
Please note that CIC (Citizenship and Immigration Canada) is working to closely manage arrivals in Canada, so that we meet, but do not exceed the immigration plan set by Parliament last fall for 2011. Since we have larger inventories than limits within the immigration plan for admissions to Canada, we must stagger the issuance of visas throughout the year. As a result, we cannot advise you when this case will be ready for finalization or when we will be in a position to communicate further requirements. No further correspondence will be entered into until we are in a position to communicate a decision or further requirements.
