The rumor that Fidel Castro was Justin Trudeau's biological father did not originate during Justin Trudeau's childhood.
Nor during Pierre Trudeau's time in office.
It appeared decades later, spreading through blogs, online forums, and eventually social media.
The theory relied on several recurring themes:
Photographs showing Pierre Trudeau and Fidel Castro together.
Claims about physical resemblance between Castro and Justin Trudeau.
Speculation about Margaret Trudeau's travels.
And assertions that official records concealed the truth.
These claims were circulated widely online.
However, no credible evidence emerged to substantiate the allegation.
