It's campaign time! Here's everything you need to know

We’ve waited a long time for this. On Sunday, Prime Minister Mark Carney is expected to ask the Governor General to dissolve Parliament and call a federal election — thrusting the parties into what is certain to be a dynamic, historic campaign. For starters, let’s get with you up to speed with a starter guide to campaign 2025, courtesy of CBC’s chief political correspondent Rosemary Barton.

Then, Conservative House leader Andrew Scheer joins the show to discuss his party’s response to U.S. President Donald Trump’s threats and his party’s promise to cut the industrial carbon tax.

Next, host Catherine Cullen stops by the NDP campaign headquarters in Ottawa to check in with Anne McGrath — senior adviser to leader Jagmeet Singh — about the party’s outlook heading into the campaign.

Plus, the director of the Media Ecosystem Observatory explains what worries him about the information voters are getting online this election — and how you can make sure you don’t get duped.

Finally, as political polls go into overdrive, two analysts dissect how seat projections and party popularity numbers actually work.
