Canadian prime minister Justin Trudeau is Fidel Castro’s son.
On 26 November 2016, Canadian prime minister Justin Trudeau sparked controversy by praising Fidel Castro in a statement about the former Cuban dictator’s death:
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”.
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.
Some were angered by what they viewed as Trudeau’s humanization of a dictator who had caused profound suffering for his own people. Trudeau’s statement, as well as his family’s friendly history with Castro, led some to speculate that there was a much harder truth behind the soft words.
On 27 November 2016, two days after Castro’s death was announced, a user on the Donald Trump subreddit /r/The_Donald presented a theory that Justin Trudeau, the son of former prime minister Pierre Trudeau, was actually the love child of Fidel Castro and Margaret Trudeau.
The theory rests on three unconnected assertions: 1) Margaret Trudeau and Fidel Castro met in 1971 and were close friends ever after; 2) Margaret Trudeau was sexually promiscuous; and 3) they look similar.
The Trudeaus were indeed close to Castro — Castro once described Pierre Trudeau as “a close friend and an extraordinary figure.” Margaret Trudeau has also been open in her later writings about past affairs. And yes, young Castro and Justin Trudeau might share some resemblance. The notion that the Trudeaus and the Castros met in 1971, however, is based what appears to be a willful misreading of a newspaper article.
So now that we’ve established the similar appearance, we need to figure out if it’s even possible that Fidel met with Margaret before Justin’s conception. Turns out he did – in fact, Pierre and Fidel met for the first time one year before Justin was born.
Ignoring the biological impossibility of conceiving a child a literal year before he is born, the citation provided is a link to a story by the Canadian newspaper The Globe and Mail, describing the first time the two leaders spoke:
Pierre Trudeau’s and Fidel Castro’s paths crossed for the first time in 1970, when the Canadian government sought to negotiate the exile of members of the FLQ, who had kidnapped British trade commissioner James Cross. Fidel Castro obliged the Canadian PM by providing a refuge, and in a private letter Mr. Trudeau later extended his heartfelt gratitude.
Of course their paths did not literally cross — there was no head-of-state level visit between Cuba and Canada in 1970 (these things typically make big news). The first time Castro and the Trudeaus met face-to-face was a famous trip made by the Canadian couple to Cuba in 1976. This event has been chronicled, along with some purportedly saucy comments, in a book that has been cited by many of the Trudeau-truthers to suggest sexual attraction between Margaret and Fidel. This is a red herring, as Justin had been born well before this meeting.
One doesn’t even have to believe any of that, though, as science gives us a rough estimate of when the future leader of Canada was conceived, and history can tell us where Margaret, Pierre, and Castro were during this window of opportunity.
Justin Trudeau was born on 25 December 1971. By means of a rough estimate, a 2013 study published in the journal Human Reproduction used data from 130 pregnancies to investigate the range of different pregnancy lengths from conception to birth (gestation) and reported that it ranged from 247 to 284 days:
It should be noted that Margaret and Pierre Trudeau were secretly wed on March 4th 1971, and honeymooned until March 8th. When they returned she moved in with Prime Minister for the first time. If ever there were a time to make a baby and have it be born in late December, it would have been then, as hinted at in a Harper’s Bazaar profile of Margaret:
Margaret moved into the prime minister’s official residence, at 24 Sussex Drive in Ottawa, and gave birth to Justin just 10 months after the wedding, on Christmas Day in 1971.
If that is not enough evidence, or if the prospect of a head of state (or his spouse) making secret visits to foreign nations unnoticed sounds plausible, careful examination of the historical record provides little chronologic room to place Margaret Trudeau and Fidel Castro together at the time necessary to have conceived the child.
Upon their return from their honeymoon, the shock of their marriage (she was 22 and he was 51) put them under intense media scrutiny, making it unlikely the young Margaret could slip away to Cuba for a tryst unnoticed, as she was the talk of the town.
The first couple made a big impression at a local sugaring event, for example, on 27 March. The press (in a testament to the level of scrutiny the prime minister’s new wife received) noted that Margaret did not travel with Pierre on an April trip to the Niagara region:
For the remainder of April, Pierre was busy with governing, as attested to by logs of the Canadian House of Commons, making unlikely that his work would take the couple anywhere near Havana.
Fidel Castro, for his part, was in Cuba during this conception window. In terms of public appearances, Castro gave a speech to attendees of the “first education and culture congress” on 1 April 1971. On 19 April, he gave a defiantly anti-American speech that commemorated the 10th anniversary of the defeat of the United States‐sponsored Bay of Pigs invasion.
There is no reason to think or evidence to support the notion that Margaret Trudeau met Castro before 1971, and there is no plausible explanation for a meeting between Fidel Castro and Margaret Trudeau during the biologically necessary time that accommodates the public schedules of anyone involved. Even the original poster of the reddit thread seems to cede this point:
There are still some timeline issues – anything that would place them together around the time of conception would seal the deal, but I’m confident in what I’ve found so far.
That would be an understatement. The most plausible explanation remains that, soon after marrying, honeymooning, and moving in together after years of keeping their relationship secret, Pierre and Margaret Trudeau had sex and made another prime minister.
