There are a number of ways to ensure that it can't be done. At first instance, the information that we receive from our data suppliers goes through a software program that leaves anything related to the patient behind. So that's at first instance, and then we have technological means to ensure that everything is totally screened out. As well, all of our contractual provisions prohibit any provision of anything that might identify a patient to us.
As I mentioned before, we are a strong supporter of patient privacy rights with respect to personal health information, and collecting anything that might identify a patient is illegal in this country, not only under PIPEDA but under all the privacy legislation. We would expect any organization that might engage in that kind of activity to be called to account and that the legislation would be enforced against them.
