We know that the action we've taken so far has saved about $300 million a year. We have coordinated bulk purchasing. That doesn't include private purchasing, but we have coordinated a lot of national purchasing through working with provinces and territories. That saved about $300 million a year. It's a significant amount of money. It's made our drugs much more competitive—so much so that we had the crisis with the United States looking to import our drugs.
However, we have more work to do. The exact quantum of how much we can save is difficult to say. There have been a lot of different estimates, but I can say that it is significant. When I talked to private insurers, they acknowledged that the ability to move to one common bulk purchasing program has the opportunity to save consumers an enormous amount of money.
