Canada (Minister of Citizenship and Immigration) v Vavilov
Canada (Minister of Citizenship and Immigration) v Vavilov, 2019 SCC 65, is a landmark decision of the Supreme Court of Canada that clarified the determination and application of standard of review in Canadian administrative law. Vavilov established a presumption that reasonableness is the applicable standard of review of administrative decisions in all cases. The case concerned the review of the Canadian Registrar of Citizenship's decision to cancel Alexander Vavilov's citizenship certificate on the basis of his parents' identity as covert Russian agents, based on an interpretation of s. 3(2)(a) of the Citizenship Act. The Supreme Court of Canada affirmed the Federal Court of Appeal's decision to quash the Canadian Registrar of Citizenship's decision, on the basis that it was unreasonable. : 3
