Donald Trump has delivered Canada an economic broadside. He says goods crossing into the U.S. will soon face tariffs. The White House insists the 25% tariff will start Saturday. Analysts say the move could sink Canada’s economy, and Americans will pay more for everyday goods. We have coverage from both sides of the brewing trade war.

And: There are five people left in the Liberal leadership race. And another one – Mark Carney – has now said he will step away from what was once a cornerstone of the party’s climate policy: the carbon tax. He and Chrystia Freeland both say they will get rid of it. Karina Gould hasn’t gone that far, but says she will block any increases. The Conservatives say the move is political – contenders trying to distance themselves from the current leader, Justin Trudeau.

Also: Climate change is likely contributing to exploding rat populations around the world. Canadian cities are among those seeing a dramatic increase.

Plus: Colleges cutting programs, midair crash investigation, Russian drones in Kherson, and more.

Sixty-seven people are dead after a midair collision near Reagan airport in Washington, D.C. A Blackhawk helicopter collided with a passenger jet carrying 64 people. Many of the dead are from the world of figure skating.

U.S. president Donald Trump spread the blame around, but focused on diversity, equity and inclusion initiatives. He says it’s “common sense” that DEI is part of the problem. But Trump was unable to say why, or what led to the crash.

Also: The deadline for Trump’s tariff threat is February 1st. Canada is still trying to stop it from happening. But if it does – Ontario businesses are planning for the future. Full tariffs could affect 500,000 jobs. The damage will likely come quickly – within three or four weeks.

Plus: Another hostage/detainee exchange, protecting the B.C. wine crop, and more.

Donald Trump’s pick for commerce secretary says tariffs on Canada could come in waves… the first this weekend, but maybe more after April 1st. Ottawa is trying to get the U.S. president’s attention with a video showing all the things Canada is doing at the border. It’s part of a last-minute push to avoid the tariffs threatened for February 1st.

Also: The Bank of Canada drops interest rates another quarter per cent. The bank’s analysis says tariffs from the U.S. could add to inflation and push Canada into a recession.

And: After a seven-year mission, a probe sent to the Bennu asteroid has brought back clues about the early solar system – and how the ingredients for life may have arrived on Earth. A handful of cosmic dust shows the asteroid once had salty water, and elements familiar on this planet. It also contains amino acids, including ones used to build proteins in living things.

Plus: Research around the globe – including here in Canada – affected by a freeze on federal grants in the U.S., tragedy at the Kumbh Mela festival in northern India, RFK Jr. confirmation hearing, and more.
