A government submission in a Supreme Court case about two sons of Russian spies argues that there is no international law requiring Canada to automatically grant citizenship to babies born here. Only 34 countries grant citizenship based on birthplace. Major nations like Australia and the UK have recently added new requirements or ended this right. A written federal submission to the Supreme Court stated: “In short, nothing in international law requires Canada to bestow citizenship on the basis of birth, much less to give citizenship to children born to parents in the service of a foreign government.”
