Mike Duffy is heading back to the Senate

Vindication and exonerationfor Mike Duffy.

The stunning acquittal of Senator Mike Duffy this week has rocked Canadian politics, the Senate, and called into question the legacy of Stephen Harper and the PMO.

To dive deep into that, we're joined by Duffy's lawyer Don Bayne, the man behind the defense in one of the most-watched political trials in Canadian history.

Then, former governmentleader in the Senate Marjory LeBretondiscusses the ruling and the governmentrepresentative in the Senate, Senator Peter Harder, also offers his take on what the acquittal means for the future of the Red Chamber.

Then,Alberta Premier Rachel Notley says in order to get to a de-carbonized future, Canada's present needs to include pipelines. She joins The House to talk about balancing environmental and economic goals, how Alberta plans to dig itself out of debt, and why she's not feeling lonely despite now beingthe sole NDP premier in the country.

While Notley vigorously opposes the Leap Manifesto, Green Party Leader Elizabeth May is an open supporter. She joins us from New York City, where she's at the signing ceremony for the UN's landmark Paris climate deal, to discuss whether Canada can deliver on the bold climate goals.

Finally, our In House panelists Rosemary Barton, host of CBC News Network's Power & Politics, and Emmanuelle Latraverse, parliamentary bureau chief for Radio-Canada, dig into the political implications of the Duffy acquittal.
