As I mentioned, when a government awards a contract to a single supplier, others have no incentive to stay in the market. I can't speak specifically to metformin, but there are other examples.
When one firm gets, let's say, 70% or 80% of the market, the other competitors are not going to make any money on this. They're likely going to stock the product, and it might go bad. It will expire and they will lose money that way. They're businesses. They need to cover their costs. Globally—and a lot of our pharmaceutical manufacturers are global—they will make the decision not to sell that product in Canada because they simply can't recoup the dollars. It's that simple. It's dollars and cents and economics.
