In doing surveillance of the products once they're on the market, one of the inputs into that is the adverse reactions that get reported to Health Canada. We know those are vastly under-reported for all products. We know they're even more under-reported for natural health products. We did a pilot with poison control centres in the past and, for example, through poison control centres, in a three-month period, they got more reports related to natural health products than we did in an entire year, so we know it's under-reported.
That's not the only input in terms of looking at the safety of the products. We look at publications. We work with our international counterparts. There is a lot of information that we look at to make sure we're assessing the safety of the products.
