Thank you very much for the question.
I think that part of perhaps some of the discrepancies can be explained in terms of how, for the permanent residency programs, we have a points system based on express entry, and I think that over the last year we are in a position now, more than we have been in the past, to actually do targeted draws around specific skill sets that the country may need: health human resources, STEM, and skilled workers in some of the construction trades. As a result of that, there's a points allocation system for permanent residency, and someone may be drawn out faster as a result of the skill sets they can bring to the country, which could explain discrepancies.
I would also note that we work very closely with our security partners, and at times what may appear to be a very similar case application can in fact be very different in the context of the information provided by the client, so it is hard to determine the measure between the two.
