Not a comparative answer.
From the Auditor General's report we have a sense of what some of the daily rates were for individuals on these contracts. As I recall, for some of the higher-end work it ranged from $800 to $1,100 per day. You'd have to do the math and figure out what the equivalent would be for a government employee. But then, of course, as Mr. Guimont pointed out, part of the reason for hiring those people is for flexibility, so that you're paying them only for the time you use them, not a full year's salary.
