U.S. Attorney General Pam Bondi said Thursday human smuggling across the border with Canada is getting worse — and that traffickers are looking north following the Trump administration's crackdown at the border with Mexico.

"The northern border, it always has been, but it's gotten much worse, much more prevalent because … it's a multibillion-dollar business, the smuggling of drugs, guns and humans," Bondi said during a news conference in Tampa, Fla.

Canada-U.S. Trade Minister Dominic LeBlanc said he left Washington Wednesday with a sense that progress was made after a meeting with U.S. Commerce Secretary Howard Lutnick.

"It was constructive in the sense it was an exchange of views that I think helped both us and the Americans understand the work we need to do to get, we hope, to an agreement," LeBlanc said in an interview with The Canadian Press after arriving in Montreal.

Canada-U.S. Trade Minister Dominic LeBlanc is set to meet with U.S. Commerce Secretary Howard Lutnick in Washington this week after Ottawa announced it would be lifting some retaliatory tariffs.

LeBlanc's office said he will travel to the United States capital on Tuesday.

Prime Minister Mark Carney announced last Friday that Canada will drop some retaliatory tariffs on U.S. products to match American tariff exemptions for goods covered under the Canada-United States-Mexico Agreement on trade, called CUSMA. .

Manitoba Premier Wab Kinew accused a group of Republicans of throwing a "timber tantrum" and playing "political games" after they called out Canada over wildfires sending smoke billowing across the international border into their states.

"These are attention-seekers who can't come up with a good idea on health care or on making life more affordable," Kinew told The Canadian Press. "So they're playing games with something that's very serious."

Canada was hit with 35 per cent tariffs on Friday after U.S. President Donald Trump followed through on his threat to increase the duties if Ottawa didn't make a trade deal.

The White House has said the tariffs would not affect goods compliant with the Canada-U.S.-Mexico Agreement on trade, commonly known as CUSMA.

Prime Minister Mark Carney had tempered expectations of an agreement by Friday, saying Ottawa will only agree to a deal "if there's one on the table that is in the best interests of Canadians."

U.S. President Donald Trump threatened to impose 35 per cent tariffs on Canadian imports on Aug. 1 in a letter to Prime Minister Mark Carney posted on social media Thursday night, evidently setting a new date for bilateral negotiations between the two countries. 

Canada and the United States had committed to working on a new economic and security agreement with a July 21 deadline for a deal. The boosted tariff pressures call into question progress toward the initial time frame.

Six Republican lawmakers have sent a letter to Canada's ambassador calling for action on the wildfires sending smoke billowing across the international border into their states.

In a Tuesday letter to Ambassador to the U.S. Kirsten Hillman, representatives Tom Tiffany, Brad Finstad, Tom Emmer, Michelle Fischbach, Glenn Grothman and Pete Stauber of Wisconsin and Minnesota said their constituents are coping with suffocating smoke from Canadian wildfires.

Prime Minister Mark Carney says Canada will take "some time" on its response to increased U.S. tariffs on steel and aluminum.

Tariffs on imports of steel and aluminum to the United States increased to 50 per cent on Wednesday after President Donald Trump followed through on his vow to double the duties.

On his way into the weekly Liberal caucus meeting in Ottawa today, Carney said Canada is in "intensive" discussions with the U.S. on trade.

Prime Minister Mark Carney will have to navigate a delicate balance during his first in-person meeting with Donald Trump today, following months of the U.S. president targeting Canada with tariffs and taunts.

Carney and Trump will meet at the White House and the prime minister has said he expects "difficult, but constructive" conversations.

Carney has said the meeting will mark the beginning of a larger economic and security agreement between Canada and the United States.

Prime Minister Mark Carney will be watched closely by Canadians infuriated by Donald Trump — and by an anxious business community looking for tariff relief — when he meets with the U.S. president Tuesday in Washington.

After months of Trump's annexation threats, the newly elected prime minister will be tasked with a delicate balancing act — showing strength while maintaining Canada's place in a critical North American trade pact the president's tariffs have sought to upend.
