To say I know it would be slightly erroneous, because my knowledge is out of date. At one time when I had checked across the board, so to speak, I think you're precisely correct, some provinces had assistance, some didn't. Ontario, for instance, did not. All through my wife's disease...$643 a month for Rilutek, and that was solely on my dime. It was not on the formulary.
Mind you, for the Ontario formulary, it only applies to seniors, so it wouldn't apply to Sari, for instance, even if it were there. It may be there now and I haven't checked, I'm sorry.
