The item you're referring to is presented as a horizontal item in the supplementary estimates, “Funding for the stabilization of the Government of Canada’s pay system”. This comprises funding for two departments.
For Public Works and Government Services Canada, it's $166.1 million. This is essentially threefold. In the first place, it is money to add capacity. They are hiring additional compensation advisers to address the backlog. Second, there are system fixes. They're going into the software of Phoenix and making changes to that system so that it functions properly. Finally, there are the changes to the underlying HR-to-pay process, looking at all of the rules, including the classification system, overtime costs, acting assignments, and promotions. All of this is being looked at to make sure it is streamlined and efficiently supports the system.
