The Prime Minister was slammed for ignoring Castro's many human rights abuses describing the communist as a "remarkable" and "larger than life leader".

In his statement he added that he knew his "father was very proud to call him a friend and I had the opportunity to meet Fidel when my father passed away".

But now a bizarre theory has surfaced online which claims that his dad, former Canadian PM Pierre Trudeau, is not his dad and he was the result of an affair his mum had with Castro.

Numerous users on Twitter have posted images the Cuban dictator and Justin Trudeau, pointing out similarities between the two.

One user posted: "Today's episode of "2016 Literally Can't Be Any Weirder," theory that Justin Trudeau is not the son of Trudeau Sr, but the late Fidel Castro".

Australian Conservative politician Peter Wallace also Tweeted, along with a picture of Castro holding Trudeau's infant brother Michel next to his mum: "Castro / Trudeau—Prima facie case (literally) that Fidel is Justin's dad. Last pic is Pierre Trudeau. #CastroTrudeau'sDad"

Some conspiracy theorists have even superimposed Castro's iconic beard onto the Canadian PM to further illustrate their case.

Other users have pointed to the fact that Trudeau's parents were both well under 6ft tall but that both he and "El Comandante" are both a similar height.

Castro stood at 6 feet 3 inches tall and the Canadian PM is 6 feet 2 inches.

US lawyer Mike Cernovich tweeted: "Fidel Castro was 6'3", Justin Trudeau 6'2", and Pierre Trudeau 5'8"."

Controversial commentator Milo Yiannopoulous has also shared an image Trudeau, his mother Margaret, and Castro with the caption: "Margaret Trudeau was promiscuous".

Others have also pointed to the fact that Trudeau's mother and father divorced and she had boasted of liaisons with other celebrities including Ted Kennedy and Jack Nicholson.

She is also quoted as saying that Castro took particular interest in her son when she and her husband, then Canadian PM visited Cuba saying: “Fidel made it clear in his opening remarks that the parents were important but not nearly as important as the baby.

"In some pictures Fidel had a big patch of wet saliva on his uniform because he had come over early to cuddle the baby.”

Castro also attended he ex-husband's funeral in Montreal when he passed away in 2000.

A statement released by Justin Trudeau's office in the wake of Castro's passing said: “It is with deep sorrow that I learned today of the death of Cuba’s longest serving President.

“Fidel Castro was a larger than life leader who served his people for almost half a century.

"A legendary revolutionary and orator, Mr. Castro made significant improvements to the education and healthcare of his island nation.

“While a controversial figure, both Mr. Castro’s supporters and detractors recognized his tremendous dedication and love for the Cuban people who had a deep and lasting affection for “el Comandante”.

He added: “I know my father was very proud to call him a friend and I had the opportunity to meet Fidel when my father passed away.

"It was also a real honour to meet his three sons and his brother President Raúl Castro during my recent visit to Cuba.

“On behalf of all Canadians, Sophie and I offer our deepest condolences to the family, friends and many, many supporters of Mr. Castro.

"We join the people of Cuba today in mourning the loss of this remarkable leader.”
