Good morning. Prime Minister Mark Carney heads to the White House on Tuesday to start high-stakes talks with U.S. President Donald Trump and try to jump-start a new relationship on trade and security. More on that below, along with the latest on Western Canadians’ discontent, and the mystery of who will dress the next pope. Let’s get to it.

The latest: Carney’s first meeting with Trump is set to take place at a low point in relations between their two countries, and the new Prime Minister is eyeing a fresh start. Carney warned again on Friday that the old relationship Canada had with the United States “is over,” and he enters the talks without a clear picture of what Trump really wants.

What’s next: Experts predict Carney will bring an outline of a proposal for co-operation between the two countries to the meeting, which would hinge on Trump dropping tariffs on key Canadian products. Ottawa’s security and defence spending, which Trump has derided as being far too low, will also surely be high on the agenda.

What to expect: Carney has tried to downplay expectations that the meeting will yield immediate results. Instead, he hopes to lay the groundwork for further talks that could bring relief from tariffs, Steven Chase and Adrian Morrow report. “But I really don’t expect removal of tariffs on Tuesday, and I don’t think anyone should expect that,” said Brian Clow, a former senior member of Justin Trudeau’s staff. “It’s going to take some time.”

Just “unlikely”? Trump said “it’s highly unlikely” that the United States would use military force to try to take Canada, in an interview that aired Sunday on NBC’s Meet the Press. “I don’t see it with Canada. I just don’t see it, I have to be honest with you,” he said. What about Greenland? “I don’t rule it out.”

The latest: With the start of the conclave to choose a new pope only days away, garment-maker Gammarelli would normally have three sizes of robes ready and on display – after all, its tailors have clothed almost every new pope for the last 180 years. Not this time, Eric Reguly reports: Gammarelli’s window is empty because it hasn’t had its usual order from the Holy See.

What’s next: It could be that the conclave will raid the closet and pick a cassock it has on hand. The Italian press has speculated that it could be a nod to the austere lifestyle chosen by Pope Francis, who died on April 21.

A gift: Another ecclesiastical tailor, Mancinelli Clero, isn’t waiting to be given an order. He has made clothes for the last three popes, and is working on white cassocks for the next in line. “I just wanted to make them,” he told Reguly. “They will be a gift for the conclave.”

The latest: Planning for prom night can be pressure-packed – not just for students, but for parents. It’s no easy task for teens to find a date, nail the right outfit, negotiate curfews and after-parties – and, increasingly, capture the big night on Instagram or TikTok.

Need help? The Globe and Mail has a guide to help parents to navigate the occasion, from “promposals” to prom pacts, the temptation to skip the night altogether and setting rules to keep students safe.

What to wear: Some eager beavers started shopping for prom dresses as early as last August. For the rest of us, don’t worry, our prom style guide can help get you suited up, whether it’s in gowns, tuxedos or vintage ensembles.

The latest: After a comeback win for the Mark Carney-led Liberals in last week’s federal election, some Albertans are feeling increasingly alienated. Almost one in four people in the province see themselves as Albertans first, and Canadians second, according to a new poll. One in 10 think their province would be economically stronger as part of the U.S.

How we got here: Western animus toward Ottawa is not new. But many Albertans felt that former prime minister Justin Trudeau neglected Western priorities during his decade in power, or even actively stymied the economic progress of regions that depend on producing fossil fuels, Nathan Vande
