This week on The House, Evan Solomon talks to NDP leader Thomas Mulcair about the controversial budget implementation bill, why he thinks the development of the oil sands is hurting the Canadian economy, and his party's plans to demand more transparency from the government.

Former DND deputy minister Alan Williams is the author of a new book on the controversial F-35 procurement process. He explains why he thinks the government misled Canadians.

The show begins with the latest on the so-called robocalls story.
