Alexander Vavilov was born in Toronto, which would typically qualify him for Canadian citizenship. But authorities had ruled that Vavilov didn't qualify because his parents were part of a Russian spy ring in North America that was broken up by the FBI in 2010. The high court rejected that finding on Thursday, meaning Vavilov can reside permanently in the country where his parents once lived clandestine lives as deeply embedded spies who were the models for the TV show The Americans.
