Fifty per cent U.S. tariffs on billions of dollars of Canadian goods have now taken effect and Prime Minister Mark Carney is vowing dollar-for-dollar retaliation after trade talks collapsed late Friday night. CBC’s Peter Armstrong lays out what we know about the breakdown at the table. Then, two former federal cabinet ministers, Canada-U.S. advisory committee member Lisa Raitt and Carney’s former chief of staff Marco Mendicino, discuss what another trade war escalation could mean for Canada’s economy and the future of free trade.

Plus, the Prairies are known as Canada's breadbasket. But could Canada boost its global agri-food exports to become the world's breadbasket? Guest host Leisha Grebinski travels to Coleville, Sask. to speak with lentil and grain farmer Dean Roberts about the technological, infrastructure and labour barriers he faces in getting more of his crops to global markets.

Evan Shout — president and CEO of financial consulting firm Maverick Ag — explains how often he hears Roberts' concerns among other farmers he coaches and why Canada's agriculture industry needs a bigger seat at the federal decision-making table.

Then, Evan Fraser, executive director of the Arrell Food Institute at the University of Guelph and Jennifer Clapp, a professor and Canada Research Chair in the School of Environment, Resources and Sustainability at the University of Waterloo, discuss whether boosting exports is the right goal for Canada, or if it should focus on food security at home.

As wildfires continue to burn out of control in B.C., guest host Chris Walker follows Conservative MP Dan Albas, whose riding includes the evacuated town of Summerland, as he travels the backroads to Penticton to where many of his constituents have fled. In this documentary, Walker speaks to Albas and neighbouring MP, Helena Konanz, about the emergency response; to volunteers and evacuees about what they have lost; and to B.C. Premier David Eby about climate change and forest management.

And, long before the wildfires made working outside difficult, the farmers of the Okanagan Valley were already having a worrying summer, as drought conditions have meant severe water rationing. In the next in our summer series on food security, The House travels to Coldstream, B.C. to meet vegetable farmer Rochelle Zelaney, as well as water scientist and former executive director of the Okanagan Basin Water Board Anna, Warwick Sears, to discuss farming in drought conditions and whether Canada’s food security will suffer.

Plus, in just a few days Canadians will find out if Trump will go ahead with imposing a crushing 50 per cent tariff on hundreds of Canadian goods. For B.C.'s lumber industry, that outcome could be fatal. Ashlee Cribb, CEO of Gorman Bros. in West Kelowna, explains the stakes for her company – and the community.

This episode features the voices of:

After a provincial politician in New Brunswick made international headlines for delivering a speech containing obvious AI prompts, and as the House of Commons continues to lean on hybrid proceedings and a voting app, it's clear technology is changing politics. But are these changes helping or hurting politicians? The House asks a panel of three past MPs: former interim Conservative leader Candice Bergen, former Liberal cabinet minister Marco Mendicino and former NDP MP and provincial cabinet minister Nathan Cullen.

Plus, as the federal government shared plans this week for a new medical countermeasures laboratory meant to improve preparedness for future health emergencies, south of the border, a Republican-led Senate committee held former top U.S. health official Dr. Anthony Fauci in contempt of Congress for declining to answer questions about COVID-19. Host Catherine Cullen checks in with Mona Nemer, Canada’s chief science advisor since 2017, about this moment in public trust and the path forward for pandemic preparedness.

And, more than half of all households in Nunavut are food insecure, according to Statistics Canada. As part of The House’s ongoing summer series on food security, Joseph Murdoch-Flowers, executive director at the Qajuqturvik Community Food Centre in Iqaluit, joins the program to talk about the work his group is doing to help and how the federal government could improve its efforts.
