Yes, we have, and I can give you a few examples.
When the federal non-insured health benefits program was transferred to British Columbia, around 17% of the medications that were covered under the federal program were no longer available through the province's publicly funded program. Those kinds of changes have to be made to ensure that patients don't lose their coverage suddenly.
I mentioned OHIP+ in Ontario, which had similar problems. Parents were showing up at the pharmacy to get a prescription filled for their child only to find out that the drug was no longer covered. Generally speaking, public plans provide less coverage. Pharmacists were having to fax doctors—because we still communicate with doctors via fax—but they weren't always available to respond. That gives you a sense of the problems that can arise.
