Canada’s leaders clap back at U.S. president-elect Donald Trump after he again said he’ll make Canada the 51st state of the United States.

In response, Justin Trudeau, who is reportedly stepping down as Canada's prime minister, recently wrote on X: "There isn't a snowball's chance in hell that Canada would become part of the United States." Trump-ally Elon Musk then responded: "Girl, you're not the governor of Canada anymore, so doesn't matter what you say."

The race to be Canada’s next prime minister is still at the starting line and Donald Trump has already cast a shadow over it.

Donald Trump's increasingly strident approach to relations with Canada is provoking fear about the potential consequences north of the border and questions about just how serious the U.S. president-elect actually is.

The president-elect keeps floating the idea that Canada, which is home to more than 40 million people and is a founding NATO partner, should join the U.S.

The president-elect said he'd use "economic force" to bring Canada into the US while also saying the Northern neighbor had nothing the US needs.
