OTTAWA – Health Minister Mark Holland has been calling around to United States officials to let them know that the Canadian government will be guarding its medical drug supply after the U.S. moved to allow states to mass import medicine from Canada. He says he’s received assurances that the U.S. government has no intention of triggering drug shortages in Canada. Health Canada issued a readout of Holland’s conversations in the past week with the U.S. secretary of health and human services and the American ambassador to Canada about the decision.
