I think one of the flaws of the Quebec model was that it was based on an insurance industry's model of what prescription benefits are, rather than an integrated model of a health benefit that includes prescription drugs.
Systems around the world that integrate medicines into their equivalent of our medicare system make sure that preventative medicines are free of charge to as many people as possible, so that at least the stuff that keeps people out of hospitals is actually getting filled when prescribed appropriately.
We have to recognize that in Quebec, for the average beneficiary of any of the plans available, there are significant monthly deductibles and co-insurance charges that just don't make sense from the logic of managing this as a health benefit. If we move forward with pharmacare in Canada, I think there is expert consensus that we want to make sure that carefully chosen medicines are available to all without financial barriers. For other medicines, there may be copayments or co-insurance, but there would be what were referred to as tiers in the formulary or in the charges for patients.
