Treasury Board has a sort of dual role in this aspect. They set the return-to-office policies for the federal public service, so they have an ability to influence how many public servants are in federal office buildings. When it comes to housing and how they can afford.... They're the ones who free up, with PSPC, the buildings that can then move to the Canada lands initiative.
Back in 2019, I think, they did a comprehensive asset expenditure review. They were looking to rationalize what assets could be disposed of and be better utilized by the public service. That initiative resulted in 119 recommendations that are meant to be addressed in order to help improve how assets are used in the public service. However, when funding sunsetted for that initiative, the centre of expertise was dissolved. While they made a lot of progress and came up with some really good recommendations, it is now left to the departments and agencies that received those recommendations to put them in place.
