His mom is in many pictures with Fidel, some quite intimately (arms across).

If his mom had an affair with Fidel, when she was in Cuba in the spring of 1971, That places Trudeau at 50 yo today.

Trudeau is 50. And his conception matches the timeline for this to be possible.

Dates check.

Found this:

It is a fact the Trudeaus were in the Caribbean in Spring 1971. It is a fact they adored Castro. It is a fact the Trudeaus were swingers. This is what you need to know. First, Margaret Trudeau, Pierre Trudeau, and Fidel Castro were all notoriously sexually promiscuous. Margaret Trudeau was a partier who unquestionably had sex with men while married to Pierre. Nobody knows if Pierre objected. They met when he was 48 and she was 18. They got married when he was 53 and she was 23.

Its fucking true.
