Anonymous- US citizens have been coming to Canada in busloads to get their prescriptions filled because it was cheaper than US was charging them, putting a strain on Canadian supplies. This was going on for years. I just checked the list of tariffs items and no mention of medicines. Here is an explanation off the news--The FDA announcement underlines the appalling gulf in drug prices between the United States and other developed nations. Pharmaceutical prices in the United States overall are more than two-and-a-half times higher than those of our peers, with manufacturers charging nearly three-and-a-half times more for brand-name drugs.
Not only are costs egregiously higher in the United States, but American patients are more exposed to those costs than their counterparts in other rich countries, as over twenty-five million people have no health insurance, and even those who do often pay steep out-of-pocket costs.
So I guess there may be a charge but albeit a minor one compared to USA drug charges.
