The Shifting Pendulum: Foreign Investors’ Liability Under Canada’s Common Law for Breaches of Customary International Law

Abstract In February 2020, the Supreme Court of Canada rendered a decision—Nevsun Resources Ltd. v. Araya, 2020 SCC 5—that can properly be described as revolutionary. In Nevsun, the court found that a Canadian corporation operating in a host state, Eretria, could be liable under Canadian domestic law for human rights abuses committed in Eritrea under customary international law, as incorporated into Canadian domestic law. The decision merits special attention because it is likely to fundamentally change the relationship between foreign investors, host states and the residents of host states adversely affected by investors’ unlawful conduct which amount to modern slavery.
