Phoenix by the numbers: Keeping track of the costs, staffing and backlog of cases

It's been 15 weeks since the federal government first gave the public a sense of the scope of the Phoenix payroll system problem.

• Phoenix deadline arrives with some 22,000 claims still in backlog
• CBC Ottawa's full Phoenix Falling coverage

• Government behind in clearing payroll backlog
