I would like to answer in English.
It's in Quebec's best interests to do the best job they can on the source of funds. So, yes, they do a lot of work towards verifying the source of funds.
Refusals down the road at the federal level involve a cost to the Quebec government, so it's obviously within their best interests to ensure that the cases that come to us have as high a chance of success as possible. So they do devote a significant amount of work to looking at the source of funds.
That being said, as Madame Deschênes has said, we still have a responsibility at the federal level. We can't simply get out of that responsibility for source of funds and admissibility, but we are working together to see what checks they're doing up front and how we can work on that process.
