A Canadian citizen at birth had his Canadian citizenship certificate cancelled because it was discovered that his parents were Russian spies. The decision by the Canadian Registrar of Citizenship was appealed to the Supreme Court of Canada where the standard of review for administrative decisions was discussed. In particular, the case helps the government of Canada set out parameters, policies and procedures for Immigration, Refugees and Citizenship Canada (IRCC) officers to use when making an administrative decision to ensure the most reasonable and fair decision gets made.
