Green Party Leader Elizabeth May sat down with five undecided voters from across the country to answer questions about how she would tackle the issues that matter most to them.

Tuesday's exchange was the third instalment of The National Presents: Face to Face with the Federal Party Leaders — a CBC News feature that gives five undecided voters five minutes each to grill one of the four federal party leaders.

Liberal Leader Justin Trudeau's turn in the hot seat came Monday and Conservative Leader Andrew Scheer had his turn Tuesday.

One of the undecided voters who spoke to May — Danny Ottenbreit, a 35-year-old farmer in Saskatchewan with a wife and a toddler — said he has concerns about how international trading relationships have hurt Canadian farmers.

Ottenbreit asked the Green Party leader about how Canadian farmers' reliance on selling to international markets could be reconciled with her proposal to produce more food for Canadians at home to reduce carbon emissions.

This week on The National Presents: Face to Face with the Federal Party Leaders:

Methodology:

The undecided voters chosen to question the leaders have been carefully selected from across the country and represent the diversity of the electorate groups — regionally, racially and ethnically, socio-economic, different ages, different priorities. Each voter is undecided, but open to voting for the leader they are across from and looking for the answers they need for a question that relates to their lives.

We invited leaders who are running national campaigns. We provided a date range in order to have them all recorded and aired in the span of one week. Mr. Bernier initially declined our offer to participate due to scheduling issues and we have since invited him for an interview later in the campaign. Mr. Blanchet was not invited as the Bloc Quebecois is only running candidates in one province.
