The design of any kind of program that would try to bring in some sort of coherent coverage regime would have to deal first of all with who's eligible, under what conditions, how are they being reimbursed for drugs, on what kind of formulary, and with what kind of copays or patient contributions.
One thing initially one would want to guard against is people finding a new initiative so attractive they remove themselves from either their existing employment-based supplementary benefits coverage, or they remove themselves from some other public plan.
The complexities around the design of drug plans are quite significant. The provincial programs, the federal government's program for first nations and Inuit, and the non-insured health benefits programs are complex things to design. I think ultimately most people would argue whether somebody has access to an employment-based program, or they have access to a publicly financed plan, the parameters should be the same.
A lot of people talk about having for example a common formulary for access to drugs for all Canadians regardless of how they have their coverage financed.
