The unofficial and untitled role of prime minister's spouse

The spouse of Canada's prime minister can play a role in advocacy and representing the country, but marriage to the country's head of government comes with no official office, functions, title or even an agreed upon form of address.

On Wednesday, Prime Minister Justin Trudeau and his wife, Sophie Grgoire Trudeau, announced that they are separatingafter 18 years of marriage.

As the prime minister's wife, Grgoire Trudeau used her position and influence to champion various charitable causes. She's spoken up about women's rights, mental health issues, eating disorders, physical activity and more. According to her Liberal Party bio page, she is an official spokesperson for Plan Canada's "Because I am a Girl" initiative and the FitSpirit Foundation.

Grgoire Trudeau also represented Canada abroad in a quasi-official capacity on occasion. She's met one-on-one with spouses of other world leaders,and accompanied her husband toevents. Russia has banned herfrom entering the country.

But Grgoire Trudeau will not be departing from any official government job by leaving the marriage.

According to the Government of Canada's Styles of Address webpage, marriage to Canada's Governor General comes with the address of "his/her excellency," but being the spouse of the prime minister does not come with its own address. Unlike the spouse of the American president, who is referred to as the first lady or first gentleman, the spouse of the Canadian prime minister does not have atitle.

Prime Minister Justin Trudeau and Sophie Grgoire Trudeau are separating after 18 years of marriage. But what actually is the role of the prime ministers spouse in Canada?

Though "first lady/gentleman of the United States" does not appear in the American Constitution, it's evolved into a semi-official position with its own office and staffin the White House. The first lady or first gentleman does not necessarily have to be a spouse the White House officially recognizes Harriet Lane, former American president James Buchanan's niece, as first lady from 1857 to 1861. Buchanan was a life-long bachelor.

In someother countries, such as the Philippines, Brazil and South Korea, the spouse of the country's leader hasa recognizedcourtesy title but no duties.

In 2021 Ukraine's first lady,Olena Zelenska,launched an annual summitfor spouses of world leaders called "theKyiv Summit of First Ladies and Gentlemen."

Grgoire Trudeau told a Quebecnewspaperin 2016that she felt she didn't have enough staff to meet the demands of her unofficial role, including speakingrequests and responding to letters. Grgoire Trudeau had one executive assistant, but a PMO spokesperson told The Canadian Press that other PMOstaff could work with her on an ad hoc basis.

Shortly after the interview, Trudeau saidhe did not want to see spouse of the prime minister become an official position.

As part of the separation, Grgoire Trudeau won't be doing speeches or public events on behalf of the government, so she won't be provided with staff, a source toldCBC News. She also won't be travelling with the prime minister on foreign trips or attending state dinners. Those details were first reported by the National Post.

Grgoire Trudeau previouslyworked as a television presenter. Earlier this year, she announced a two-book deal with Penguin Random House. A description of one of her forthcoming books on Penguin Random House Canada's website describes her as a "de facto first lady."
