What will your ballot box question be?

This week on The House, as Canadians get ready to head to the polls, we look at the ballot box issues framing the election.

What are the ballot box questions for each of the three main federal parties? We speak with politicians who were part of the last campaign, but chose not to run this time: the Conservative James Moore, the NDP's Libby Davies and the Liberals' Bob Rae.

Then, the CBC's polls analyst Éric Grenier looks at each party's path to victory, province by province. In the last of our Battleground Watch, it's all about the electoral map!

But what happens if no party manages to secure a majority of seats? We play What If? The Parliament Edition with University of Ottawa law professor and constitutional scholar Adam Dodek, who walks us through a variety of possible outcomes on Oct. 19 — and what would happen next.

Finally, we wrap up our In House election coverage with panelists Rosemary Barton, host of CBC News Network's Power & Politics, and PostMedia columnist Andrew Coyne, with the story lines you should be watching for on election night.
