Justin Trudeau was conceived around March 1971 and born in December 1971 in Ottawa. Margaret and Pierre Trudeau were both living in Canada during that period; their travel logs, government schedules, and media appearances are well recorded. Fidel Castro was in Cuba throughout early 1971 and did not meet the Trudeaus until 1976. No official documents, eyewitness accounts, or credible reports place Margaret Trudeau and Fidel Castro in the same location prior to that diplomatic visit.
Despite the clear chronological contradictions, the story continues to circulate — largely because it fits into the broader pattern of conspiracy culture and celebrity fascination in the internet age. The rumor resurfaced with particular intensity after Castro’s death in 2016, when Justin Trudeau’s public statement of condolence was interpreted by some as unusually emotional. Online users, especially on social media platforms and certain political forums, used this moment to revive the unsubstantiated paternity claim.
