I'm very confident, since 2016, that Public Services and Procurement Canada is doing a lot to try to improve the situation, but there is a complex web of rules.
I would like to highlight one thing: There will always be pay action requests. I don't think anyone should expect that it will come down to zero, because some of those pay action requests are about changing a bank account or moving to a new address. However, those that address an individual being over- or underpaid should be collected.
