They say it's 12 months from the date they receive an application to decision made (important, not even COPR received, but just DM). So, landing is not included in the "1 year process" and I think 13 months with landing is still inside normal time
Again, don't want to frustrate you, but ...
but I've never seen a single case when an application should have been sent to Warsaw (i.e. belongs to Warsaw by their internal logic) but was sent to Mississauga instead. I have no clue about the reason. But it's a fact. Maybe you'll be an exception
