So how did Trudeau and Trump's dinner meeting go? Here's what we know

Prime Minister Justin Trudeau and U.S. president-elect Donald Trump discussed border security and Canada-U.S. trade during a surprise meeting at Trump's estate in Florida on Friday night.

Trudeau flew to Palm Beach, Fla., and visited Trump at Mar-a-Lago, where the president-elect has been meeting with his transition team in recent weeks. The visit came amid Trump's threats to impose steep tariffs on Canadian products entering the United States.

On Saturday, Trump described the meeting as "very productive" on his social media channel Truth Social. In a post, Trump said he and Trudeau discussed the fentanyl and drug crisis, illegal immigration and Canada-U.S. trade.

"I made it very clear that the United States will no longer sit idly by as our Citizens become victims to the scourge of this Drug Epidemic, caused mainly by the Drug Cartels, and Fentanyl pouring in from China," he wrote.

"We also spoke about many other important topics like Energy, Trade, and the Arctic," Trump added. "All are vital issues that I will be addressing on my first days back in Office, and before."

A Canadian government source who spoke confidentially to CBC News said there was no guarantee that tariffs are coming off the table, but the Canadians left the meeting with optimism that a solution is attainable.

The source also said Trudeau promised to increase security along the Canada-U.S. border and specifically told Trump he'll increase helicopter patrols.

One thing that struck Canadian officials, the source said, is how important the fentanyl issue is to Trump and that anything Canada can do to help is key.

Overall, Canadian officials felt they made good connections on Friday and now know key players on Trump's new team, the source said. Trudeau was joined on the trip by Public Safety Minister Dominic LeBlanc and his chief of staff, Katie Telford.

On Saturday, LeBlanc told CBC News he was "struck" by "how cordial the relationship is between the prime minister and [president-elect] Trump."

When asked whether Trump cancelled his tariff threat, LeBlanc said the president-elect "hasn't imposed them yet and he's not president."

"We talked about how the Canadian economy and the American economy depend on each other," the minister said. "And we talked about how difficult the imposition of tariffs would be on many American consumers and why it's in our interest to work together on shared security concerns."

Pennsylvania senator-elect Dave McCormick posted a photo to social media platform X late Friday showing Trudeau sitting beside Trump during dinner at the Florida estate.

Those in the photo include McCormick; Howard Lutnick, Trump's nominee for U.S. commerce secretary; Gov. Doug Burgum of North Dakota, the pick for interior secretary; and Florida Rep. Mike Waltz, the national security adviser nominee.
