Once again, U.S. President Donald Trump is threatening to slap more tariffs on Canada — and Pierre Poilievre has thoughts. The Conservative leader speaks with Catherine Cullen in his first national English interview with CBC since becoming party leader to discuss how he’d tackle the Canada-U.S. trade war differently and why he thinks he deserves a second shot at holding a seat in the House of Commons.

Then, national security expert Wesley Wark explains why Trump’s latest move should elicit a bigger response from north of the border.

Plus, the new head of the Royal Canadian Air Force, Lt.-Gen. Jamie Speiser-Blanchet, tells The House her priorities for the new role in a “volatile and uncertain” time.

Finally, as Prime Minister Mark Carney’s chief of staff and the new Clerk of the Privy Council officially take the reins of the federal government, Janice Charette, a former clerk who assisted with the Carney transition, and Ian Brodie, former chief of staff to Prime Minister Stephen Harper, lift the curtain on the high-pressure roles and examine the challenges of executing the prime minister’s ambitious agenda.

This episode features the voices of:

• Pierre Poilievre, leader of the Conservative Party of Canada
• Wesley Wark, senior fellow at the Centre for International Governance Innovation
• Lt.-Gen. Jamie Speiser-Blanchet, commander of the Royal Canadian Air Force
• Janice Charette, former Clerk of the Privy Council
• Ian Brodie, former chief of staff to Prime Minister Stephen Harper

Canada-U.S. trade once again became the hottest topic in town after Donald Trump said he was walking away from the negotiating table over the federal government’s digital services tax. Just a few days later, Prime Minister Mark Carney rescinded the tax. Was that a smart move? Two trade experts join The House, guest hosted by CBC’s trade reporter Janyce McGregor, to discuss the retreat and the looming July 21 deadline for a deal.

Plus, The House talks to cheesemakers at a festival in Kingston, Ont. about concerns Trump’s tariff threat will spell the end of Canada’s protection of its dairy industry. Then, a Saskatchewan cattle rancher explains why she’s frustrated over a recently passed bill that protects that supply management system from Canada-U.S. trade talks.

Next, as Canada’s trade relationship with the U.S. remains uncertain, it needs other allies more than ever. In his first broadcast interview since being named to cabinet, International Trade Minister Maninder Sidhu explains why making up for lost trade with the U.S. is hard to do.

Finally, trade policy and negotiations used to be dominated by economic data, legal rules and a ton of fine print — until Donald Trump flipped the table. Dmitry Grozoubinski, an Australian trade consultant, discusses his book, Why Politicians Lie About Trade, and how to spot the misformation to be able to make sense of (and even poke fun at?) the current state of trade debates.

This episode features the voices of:

• Inu Manak, fellow for trade policy at the Council of Foreign Relations
• Julian Ovens, former chief of staff for two international trade ministers
• Roxanne Renwick, cheesemaker
• Shep Ysselstein, cheesemaker
• Hans Weber, cheesemaker
• Karla Hicks, board member of the Canadian Cattle Association
• Maninder Sidhu, Minister of International Trade
• Dmitry Grozoubinski, author of Why Politicians Lie About Trade

It was all going well — until it wasn’t. On Friday afternoon, U.S. President Donald Trump announced he was ending all trade discussions with Canada and blamed the federal government’s digital services tax, set to take effect June 30. So what now? Former deputy prime minister John Manley joins The House to discuss what Ottawa can do next.

After that, as federal parties hit the summer barbecue circuit and prepare for the fall session of Parliament, Liberal strategist Marci Surkes, Conservative strategist Kate Harrison and NDP strategist George Soule reflect on what’s changed for their parties and look at the political road ahead.

Plus, some disabled Canadians will be able to receive up to $200 a month from the new Canada Disability Benefit — but not everyone qualifies. B.C. resident Shauna Milne explains how she tries to make ends meet. Then Heather McCain, Executive Director of Live Educate Transform Society, weighs in on how Ottawa can make it easier to apply for the benefit.

Finally, Catherine Cullen asks politicians about the best political advice they’ve ever received and hears a wide range of tips and tricks. For starters: don’t eat the free cookies.
