I'm not a specialist of that kind of increase of delegation of authority, and maybe Franck can add to my answer, but I would say that those requests are made, as you said, regularly to update and review the delegated authority for a department.
What I know is that we first received our delegated authority in 1993. It was reviewed in 2000 and 2006. It was adjusted in 2019 and, finally, in 2022. It started at $3 million and went up to $4 million. Ultimately, in 2022, it was increased to $10 million for the purchase of official residences.
What I understand from the process is that a thorough analysis is done in a Treasury Board submission to describe how the markets for this kind of asset evolve. I believe, from what I've read, there were 23 different markets studied, and the result of that study showed that the average cost for a building that would be in the category of an official residence was around $9.5 million, therefore explaining why—I assume—the Treasury Board gave us that authority up to $10 million.
