My colleagues from the procurement branch would probably be able to provide a more definitive response, but there are two approaches. One is that procurements are typically done on a competitive basis and, through the competition, there is an incentive for bidders to ensure that the price they're submitting is going to be competitive, to increase the likelihood or chances of their being successful on it.
In instances when there's something really unique, either because we're buying something that only one company has or because there's a specific geographic component, where what would be considered directed or sole-sourced contracts would come forward, within the department, we do have cost analysts who are able to undertake assessments of the proposed price to determine whether or not it represents fair market value in terms of what the company charges other preferred clients, and so on.
Within the department, there are some activities and initiatives we have to be able to take a look at the question of value for money, as it's more commonly defined.
