When the federal government announces it's buying the Trans Mountain pipeline project for $4.5 billion, there's really only one thing to do: convene a special edition of At Issue to break down what it means for Ottawa, Alberta, British Columbia and Canadian taxpayers.

Doug Ford’s in the middle of a membership scandal, Andrea Horwath tried to explain a billion dollar mistake in her costing plan, and Kathleen Wynne basically tried to stop the bleeding.

The federal government says it's not happening. Rosemary Barton hosts Andrew Coyne, Chantal Hébert and Eric Grenier.

Bill Morneau is breaking out the taxpayer's wallet to help Kinder Morgan's Trans Mountain Expansion weather British Columbia's storm, is that going to be enough?

Quebec's Roxham Road still sees a steady stream of asylum seekers- and it's predicted to get bigger when the warmer weather really gets here.

The pipeline spat is still going- and all sides are digging in. Sources are now saying that the federal government has a Plan B if Kinder Morgan drops out- they'll be courting other companies to invest.
