I think ideas like that are already outlined in the procurement policy and in the supply manual that Public Services and Procurement Canada has out there.
I would tell you that every department or agency should have its own procurement group or directorate that has a challenge function and has some oversight over procurements. Also, at certain contracting levels, Public Services and Procurement Canada plays that role, but those supply manuals and policies talk about how, depending on the size or the magnitude, you could put committees together, etc. There are a whole bunch of mechanisms already outlined.
That's why many of our recommendations are to follow the existing policies. There's no need to create more. Oversight exists. It's a matter of actually putting it in place when it's appropriate.
