This week — as part of the CBC series Face to Face — five undecided voters got five minutes each with federal party leaders to ask the questions that matter most to them. The National's Rosemary Barton hosted the events, and followed up with questions for Liberal Leader Justin Trudeau, Conservative Leader Andrew Scheer, Green Party Leader Elizabeth May, and NDP Leader Jagmeet Singh.

Today on Front Burner, Barton reflects on what she learned from the exchanges, and what they might tell us about what's at stake with the upcoming federal election.
