It started as a joke. In December 2024, Donald Trump glibly told Justin Trudeau that Canada should become the 51st state. Three months later, the “joke” seems to have become an American foreign policy goal for the second Trump administration.
Canadian Parliament has been unanimous in its response: “Canada is not for sale.” But Canada’s head of state, King Charles, has remained largely silent on the matter — until recently.
Over the last several weeks, observers have started to pick up on subtle signs of support for Canadians from the King. But many people have no doubt been wondering why there’s not been a direct statement of support from King Charles.
The answer to that question isn’t as simple as many people might think.
King of Canada
Since 1689, Britain has been a constitutional monarchy. The sovereign is the head of state, but the prime minister leads the government. As such, the King can’t interfere with politics. He is supposed to remain neutral and be the embodiment of the nation.
This crucial separation between palace and Parliament was solidified in Canada and throughout the Commonwealth in 1931 with the Statute of Westminster. In 1954, the Royal Styles and Titles Act separated the British Crown from the other Commonwealth realms. Queen Elizabeth became the first sovereign to ever be called Queen of Canada.
As a constitutional monarch, King Charles is bound by parliamentary limitations on his authority. He cannot act without taking advice from the prime ministers in his various realms.
This means King Charles can’t make a political statement about the ongoing tensions between Canada and the U.S. without the green light from Ottawa. When asked about the situation in January, a palace official said simply that this is “not something we would comment on.”
As former Alberta premier Jason Kenney later explained on social media:
“For Canadians disappointed that King Charles has not commented on President Trump’s threats to annex Canada: in his capacity as King of Canada, he can only act on the advice of his Canadian first minister, i.e. Justin Trudeau.”
Or, at this moment, Mark Carney.
Signs of support
The King met with Trudeau at Sandringham, the royal family’s private estate in Norfolk, England, on March 3. This meeting seems to have prompted a series of symbolic gestures demonstrating the monarchy’s solidarity with Canadians.
The next day, the King conducted an inspection of the British aircraft carrier HMS Prince of Wales in his capacity as head of the Armed Forces. Canadian medals and honours adorned his naval dress uniform during the inspection.
A week later, the King planted a red maple tree at Buckingham Palace to honour Queen Elizabeth’s commitment to the preservation of forests and the bonds among Commonwealth nations.
On March 12, the King met with representatives from the Canadian Senate.
He presented a ceremonial sword to Gregory Peters, the Usher of the Black Rod (one of the Senate’s chief protocol officers). Raymonde Gagné, the speaker of the Senate, was also present for that meeting.
And on March 17, the King met with Carney as part of the new prime minister’s whirlwind diplomatic tour of western Europe.
Some observers even pointed to the Princess of Wales’s red dress at the Commonwealth Day Service of Celebration on March 10 as yet another nod of recognition for Canada.
Soft power and the Royal Family
These sorts of gestures are examples of what is known as “soft power.” Unlike the hard power of military and economic force used by governments, soft power describes any number of ways that people or groups can influence others through culture, personal diplomacy and even fashion.
As one Buckingham Palace source remarked: “The King knows that seemingly small gestures can send a reassuring sign of recognition about what is going on around the world.”
One of the best known forms of the monarchy wielding soft power is through the use of state visits. At the British prime minister’s request, world leaders are invited to London by the sovereign. The red carpet is rolled out for them, they’re wined and dined in lavish dinners at Buckingham Palace and they often make a speech to Parliament.
These state visits are a way for the Royal Family to use its soft power to positively influence diplomatic relations.
In February, British Prime Minister Keir Starmer presented Trump with an invitation from the King for a second state visit to the U.K.. So far, no date for the trip has been announced, but the King’s meetings with Trudeau and Ukraine’s Volodymyr Zelenskyy reportedly irritated Trump.
It remains to be seen how King Charles navigates his constitutional role as both king of the United Kingdom and of Canada. Will Trump’s state visit only be about British interests? Or will Charles use it as a chance to address the concerns of his Canadian subjects?
