It's a standard reply they have been sending for the last 4-5 months.
and this has mostly (99.99%) been sent to ND applicants. I guess they got more applications in ND than any other offices.
On the other hand CHC London is sending the following reply:
Thank you for your enquiry.
Your documents are now on file.
CIC is working closely to 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 of applications than limits within the immigration plan for admissions to Canada, we must process applications according to the priorities set by Parliament. As we have a sufficient number of applications in our high priority categories, we are not in a position to process your application at this time, nor can we predict when processing on your application will resume.
