These moments, widely documented by both Cuban and Canadian media, helped forge a perception of closeness between the two families. However, the warmth of that political friendship decades later became the foundation for speculative narratives about a deeper connection — a pattern that often emerges around charismatic or controversial public figures. One of the strongest drivers of the rumor has been visual similarity. Many internet posts and tabloid outlets have published side-by-side photos of a young Fidel Castro and Justin Trudeau, pointing out similar facial structures, expressions, and gestures.
While these comparisons are eye-catching, experts in genetics and facial morphology note that such similarities are not uncommon and cannot be used as evidence of familial connection. Many unrelated individuals share striking resemblances, especially when compared selectively or under similar lighting and expressions. Photographs of Justin’s father, Pierre Trudeau, during his youth also reveal significant resemblance — particularly around the eyes and smile — further weakening the speculative argument.
