Calian does receive a certain percentage of the money that they charge the defence department. A certain proportion of that money they keep for overhead; I can't recall the exact percentage, but I think it's between 10% and 20%—something like that—because of all the recruiting they have to do. But then, they all pay whatever the market rate is above that to pay for the salary of the clinician who's hired to do the job.
They have much greater flexibility, nimbleness, and speed with which they can find and hire people, not just with respect to process, but also in their ability to pay what the local market demands. It won't necessarily be one pay scale that they'll apply for physicians or physiotherapists, say, across the country. Depending on the specific region and the difficulty in attracting people to work in that specific region, they have the liberty and the flexibility to increase the charge or the salary in order to be able to attract people and fill the capability gap.
