In 2019, Nova Scotia’s then-Liberal government passed the Coastal Protection Act — legislation that would have brought in regulations around building near the coast. In 2021, the Conservatives were voted into power, and it sounded like they were keen to keep the Act in place.But in February 2024, Nova Scotia’s government announced that they wouldn’t. Instead, the responsibility for regulating coastal development would be downloaded onto municipalities, and in some cases, even homeowners.Matthew McClearn is a data journalist for the Globe’s energy and environment team. He’s on the show to talk about what Nova Scotia’s abandonment of the Coastal Protection Act tells us about their approach to climate adaptation, and what happens when a province makes climate change an issue of personal responsibility.Questions?

On October 14, the RCMP shared explosive allegations linking Indian government officials to homicides, extortions and coercion committed against Canadians, on Canadian soil. The RCMP said 30 people had been charged so far, and Ottawa announced it was expelling 6 Indian diplomats.  Since the escalation, The Globe has learned the lengths Ottawa and the RCMP went to, to avoid worsening tensions between the countries. The Globe’s Ottawa Bureau Chief, Robert Fife, takes us inside the behind-the-scenes meetings that led to Canada’s escalation, how far up this goes in the Indian government, and what this all means for the future of Canada and India’s relationship. Questions?

The U.S. election is a week away, and tensions are running high. Polls show Harris and Trump as more or less deadlocked. America’s Electoral College means the presidency is won one state at a time — and in a country that vast, it’s hard to capture the nuances of the race in the snapshot of a poll.That’s why the Globe’s feature writer, Ian Brown, got on a Greyhound bus in downtown Los Angeles, and headed east for New York City. He and photographer Barbara Davidson traveled from the deserts of the Southwest to the dairy farms of Wisconsin to try to understand what people were thinking about the election. Ian’s on the show to talk about how taking the bus shaped his thinking about American politics, and he shares some excerpts from his feature on the trip.Questions? Comments? Ideas?

On Thursday, Prime Minister Justin Trudeau announced a major reduction in the number of permanent residents the country will admit over the next three years, saying his government had not gotten the balance between labour needs and population growth “quite right.”In 2025 and 2026, the government had initially planned to bring in 500,000 permanent residents – now, they’ve set a target of 395,000 and 380,000, respectively. In 2027, that target is 365,000 permanent residents. This signifies a major policy reversal for the Trudeau government – and would mean that Canada’s net population is projected to decline by 0.2 per cent per year over the next two years.Marc Miller, Minister of Immigration, Refugees and Citizenship, joins us to discuss why the government is cutting Canada’s immigration targets, and why he says Canadians should trust the Liberals to fix the problem.Questions?

Republican presidential candidate Donald Trump has said he will impose 10 to 20 per cent tariffs on everything the U.S. imports. This would include, it seems, all of the goods and resources Canada sells to its biggest trading partner. And that kind of tariff wall could have serious effects across the Canadian economy.Adrian Morrow is the U.S. correspondent based in Washington, D.C., for The Globe and Mail. He looked at exactly which parts of the Canadian economy would be hit the hardest, how much each Canadian could stand to lose on average and what Canada is doing to prepare for this possible scenario.Questions?

The hearings for the public inquiry into foreign interference led by Justice Marie-Josée Hogue wrapped up earlier this week with testimony from Prime Minister Justin Trudeau. The Prime Minister said he had the names of Conservative parliamentarians who were engaged in or at high risk of being targeted for foreign interference. Trudeau’s testimony came just two days after the RCMP announced they had evidence of Indian officials’ involvement in homicides, extortion and violent crime on Canadian soil, which led to Canada expelling six Indian diplomats, and India expelling six Canadian diplomats in retaliation. Steven Chase is the Globe’s senior parliamentary reporter. He’s on the show to break down Trudeau’s testimony, what else we learned from this round of the inquiry into foreign interference, and how the new revelations about India played into all of this.Questions?
