MONTREAL -- Local candidates vying for a seat in parliament clashed at Dawson college Thursday in front of a packed auditorium.

They were debating their parties' environmental policies, but Michael Forian, a conservative candidate for Ville-Marie—Le Sud-Ouest—Île-des-Sœurs, went on the offensive. He attacked the Liberal government's track record, prompting laughter and eye-rolling from the audience.

A representative for Dawson college said so many people arrived to watch the debate that they had to move it to a larger room.

Around 400 people came to watch.

Who won the debate?

"The Green Party, they were the ones who were always on point," one student said.
