During the 4 Nations Face-Off championship game between Canada and the United States, Canadian singer-songwriter Chantal Kreviazuk performed the Canadian national anthem, "O Canada," but with a noticeable lyrical change. While some initial boos arose from the Boston crowd, Canadian fans soon joined in, singing along with Kreviazuk's rendition.

Instead of the traditional line, "True patriot love in all of us command," Kreviazuk sang, "True patriot love that only us command." This alteration didn't go unnoticed by some Canadian fans, and it was later confirmed by her publicist that the change was intentional, a direct response to what was described as "annexation rhetoric" coming from the United States.

Kreviazuk further hinted at her intentions by sharing an image on her Instagram Stories displaying the altered lyrics written on her hand, accompanied by emojis of a flexing arm and a Canadian flag. The context for this lyrical shift lies in comments made by former President Donald Trump, who on several occasions, including before the game, suggested that Canada could become the 51st US state, even referring to Canadian Prime Minister Justin Trudeau as "Governor Trudeau." According to Team USA general manager Bill Guerin, Trump reiterated the "51st state" remark during a call with the American team on the morning of the game.

This incident follows a series of national anthem-related reactions stemming from earlier in the month. Ottawa Senators fans booed the "Star-Spangled Banner" on February 1st in response to impending US tariffs on Canadian goods (since delayed), and similar displays occurred during a Toronto Raptors game and Team USA's first 4 Nations game in Montreal. Following Kreviazuk's performance, American fans united in a robust rendition of the "Star-Spangled Banner."
