Maybe I can start answering that one.
On the second part, the cost as a consequence of people not filling prescriptions, there is not to my knowledge any good data that explains what those costs are. We do know that individuals who forgo medications, particularly for chronic diseases, and others, but particularly chronic diseases, do run the risk that their condition will deteriorate and that they will make demands as a consequence on other aspects of the health care system, be it emergency room services, surgeries, and so on.
In terms of those who face the most difficulty in terms of access to drugs because of our current coverage regimes, social assistance recipients are eligible in most provinces for coverage. It's those individuals with relatively low incomes—I won't call them the working poor—who have inconsistent affiliation with a workplace. They may work multiple part-time jobs. They may be working part-time. But the nature of their employment is such that they do not have an employer-based supplementary benefits program.
Those individuals are among the ones who face the greatest difficulties. They may also have their situation compounded by being single parents or circumstances of that nature. It's generally people of working age, because seniors are generally covered, with enough income to have passed the income thresholds for eligibility, so they're not eligible for fully subsidized coverage and they don't have any access through their employment. That's the sort of broad category of people who lack appropriate coverage.
