Despite what you said, I'll bring up the Canada‑Quebec accord again.
First, this accord contains a multiplier that increases each year, regardless of the immigration levels set by Quebec. These levels have remained stable. You spoke of imbalances, so I identified one for you.
Second, under the same accord, the system of payment agreed upon for a number of years resulted in surplus amounts being allocated to Quebec. We haven't yet had a very public discussion with Quebec about this issue. However, Quebec received substantial payments, far more than it should have been allocated. In my opinion, the exchange of invoices should be discussed with the governments responsible for the matter, in this case the Quebec government.
