Within hours of the U.S. Supreme Court striking down U.S. President Donald Trump's broad tariffs, Trump announced 10 per cent global tariffs and listed other avenues for further levies. Michael Solberg, Zain Velji and Carlene Variyan break down whether Canada could end up worse off, and look back on how big the loss of a third floor-crosser to the Liberals is for the Conservatives.

Conservative public safety critic Frank Caputo tells Power & Politics that the Conservative caucus is still behind leader Pierre Poilievre after a third floor-crossing to the Liberals, saying 'the mood for me is one of business as usual.' The Power Panel reacts. Then, asked what U.S. data showing its global trade deficit hitting a record high says about the effectiveness of U.S. President Donald Trump's tariffs, economist Justin Wolfers responds with a laugh.

The U.S. Supreme Court ruled on Friday that the broad tariffs President Donald Trump justified with national emergency powers — including the 35 per cent imposed on non-CUSMA-compliant Canadian goods — are illegal, leading Trump to immediately announce a global 10 per cent tariff through a different legal avenue. Canada-U.S. Trade Minister Dominic LeBlanc responds to questions about whether Canada will still enjoy a CUSMA exemption by saying the U.S. never granted it 'because they want to be nice to us,' but because it's in the 'American economic interest.' Then, Alberta Premier Danielle Smith defends her plan for an October referendum that would ask about imposing fees and limitations on services for immigrants without certain statuses, as well as constitutional changes like abolishing the federal Senate.

CBC's Rosemary Barton explains everything we know about Alberta Conservative MP Matt Jeneroux's decision to cross the floor to the Liberals, and rumours that more Conservatives could still follow. Then, former Conservative campaign manager Fred DeLorey and former Liberal campaign co-chair David Herle discuss the potential of a Liberal majority, which could now be completed with a win in a Quebec vote that DeLorey calls 'the most consequential byelection in Canadian history.'

Prime Minister Mark Carney announces a bold new 'buy Canadian' plan to build up Canada's military. Power & Politics hears from Industry Minister Mélanie Joly. Plus, Mark Wiseman begins his new job as Canada's ambassador to the U.S. The Power Panel weighs in.

U.S. Democrats have launched an investigation into President Donald Trump's threat to block the opening of the Gordie Howe International Bridge, which connects Windsor, Ont., and Detroit. Power & Politics hears from Windsor Coun. Angelo Marignani. Plus, NDP leadership candidates face off in a last debate this week. Two of them join P&P with their vision for the party.

Prime Minister Mark Carney and the leaders of every party in the House of Commons came together to lay flowers at a memorial in Tumbler Ridge, B.C., on Friday, before attending an evening vigil in the community. NDP interim Leader Don Davies, Green Party Leader Elizabeth May and the region's provincial MLA Larry Neufeld join Power & Politics to reflect ahead of the vigil. Plus, the RCMP reveal more information about the weapons used in Tuesday's mass shooting.

Is there a coalition forming between Prime Minister Mark Carney and Conservative Leader Pierre Poilievre? Our panellists certainly wouldn't go that far. But Carlene Variyan, Rachael Segal and Laura Stone are here to break down signs that the parties are working together to avoid further parliamentary gridlock and the potential of a spring election. Then, a reflection on how Canada's leaders came together in response to the mass shooting in Tumbler Ridge, B.C.
