Thank you for the question.
As I said in my answer to the previous question, the issue is one of procedure. Information is exchanged every day between various departments, including between the different levels of government. Technology allows that.
The modalities of the agreement, and where the administration would be done, must be clear. It must be clear when federal administration would come into play and where provincial administration would step back, and vice versa.
Then, if it turned out to be more of a technical modality, it would have to be clear how the exchanges would be made, in order to make sure that there were no interruptions. We also have to consider the ability to make changes quickly, if required. Just think of the situation we experienced during the COVID-19 pandemic when, in the space of a few weeks, amounts were increased in order to help Canadians. Naturally, it would involve additional costs, depending on the arrangement that is negotiated.
