Mr. SP is a retired pharmacist, so this was on his radar in the spring. From what I understand, the owners of Canada Drugs also operated a wholesale drug business that was separate. They were found to be selling a couple of counterfeit cancer drugs through the wholesale business. It's been unclear (at least as far as I can tell) whether that was deliberate or that they were victims of a scam. End result was cancer patients not getting the proper treatment, so the optics (and results!) are terrible for this. CVS has also been found to be dispensing counterfeit drugs in the past (Lipitor), so it's an issue for all pharmacies nowadays.
There's no evidence or claim that any drugs sold through the Canada Drugs website have ever been anything but what they were supposed to be, but they agreed to shut everything down in order to make the deal with the DOJ. There was probably some prodding from the drug lobbies too. I'm sorry you're losing your source of cheaper drugs (you were buying HRH's medications through them, weren't you?) We complain like crazy here about drug prices, but when I see what you guys are paying, it just boggles my mind.
