As I explained earlier, 900 service providers across the country meet our criteria. Clients are free to go and see the service provider of their choice, provided that provider meets our criteria. We then reimburse for treatment expenses. In one sense, that's very different from what is done in the Canadian Forces. In their case, contracts are established with service providers, and forces members are referred to them. In our case, it's a matter of free choice.
To be a service provider, you have to meet training and experience criteria. We don't have any contractual relationship with those suppliers. We can't impose practices. Our role is to ensure that clients are satisfied and to improve the training and supervision of those providers. Since we don't have any authority, the practice of those providers is the responsibility of their professional order, in the province where they are located. We're in the process of improving training for service providers. In addition, the OSI treatment clinics have a role to play in training.
Our role is also to improve our relations with service providers so that they can work with the specialists at the OSI treatment clinics. The objectives is to enable them to improve their practice. To do this, they can discuss the best approach to adopt with the professionals and experts. We also aim to further standardize reports and information that we want to receive when we are asked to approve a series of treatments.
Clients may consult the therapist of their choice, but they must seek pre-authorization from us where they exceed a certain number of treatments. In that respect, we're working to improve our policy and our instruments, particularly with a view to offering the right answers and asking the therapist the right questions and to ensuring that the treatment heads in the right direction.
