Ten years after the Phoenix pay system launched, the federal government is replacing it with a new human resources and pay system, Dayforce. On March 23, 2026, Auditor General Karen Hogan tabled an audit of that project. Dayforce has not gone live in any department yet, and the audit looks at the risks before it does.
The main finding
The Auditor General concluded that the Treasury Board of Canada Secretariat and Public Services and Procurement Canada (PSPC) were managing the project so they can ensure accurate, on-time pay and value for money once it is implemented. The report stresses that the project is in its early stages and that there is still time to address the risks it identifies.
The cost
PSPC's preliminary estimate for Dayforce is more than $4.2 billion. The audit says this did not include important costs for all departments and agencies to transition. PSPC is still working out how it will measure the savings the new system is supposed to deliver.
Pay rules were not simplified
After Phoenix, a key lesson was to simplify and standardize pay rules before launching a new system. "It is concerning to me that, a decade later, there has been little progress made to simplify these rules," Hogan said. "As a result, the department is customizing the new Dayforce pay system at an estimated additional cost of almost 4 million dollars per year."
The backlog
As of Sept. 30, 2025, the Public Service Pay Centre had a backlog of 233,653 pay transactions affecting 133,619 employees. Of those, 155,217 were more than a year old. The audit warns that if the backlog is not cleared before the move, existing errors could carry over into Dayforce.
A shorter schedule
PSPC had planned to finish replacing Phoenix by 2034. In January 2026, after the audit period, it shortened the schedule by about three years. The Auditor General said this reduces the time available to clear the backlog and prepare departments.
Since then
PSPC's own Question Period notes say that, as of May 20, 2026, the inventory of transactions waiting at the Pay Centre was down 67% from its January 2018 peak. They say enterprise testing was set to begin in summer 2026, and the first three organizations, the Canadian Nuclear Safety Commission, PSPC and Shared Services Canada, have a planned go-live in 2027 to 2028. The audit set April 1, 2027, as the target to clear the backlog for PSPC and Shared Services Canada.
Should the Phoenix backlog be fully cleared before any department moves to Dayforce?
