Frontier injustice: the American threat to Canada's drug supply.

"Import-from-Canada" strategies to address high prices for patented pharmaceuticals are gaining momentum in the United States. In the first two months of 2019 alone, five congressional bills incorporating such strategies were introduced; these bills have attracted bipartisan support across the fractious American political divide. At the same time, Canadian lawmakers continue their long-standing failure to take action in response to the looming threat of having Canada's drug supply siphoned off by its more powerful neighbour. Unregulated bulk importation of pharmaceuticals originally intended for the Canadian market into the USA would lead to severe drug shortages that would undermine the Canadian health system, while also halting emerging moves towards universal Canadian pharmacare in their tracks. At the same time, this short-term approach to tackling American pricing woes would fail to heal the deep systemic issues that underpin unaffordable drug prices in the USA. This article underscores the need for Canada to take action to protect its supply of patented medicines, and suggests possible forms such action might take.
