I think Canada deserves a forthrightly left electoral alternative. I don't see the advantage for our democracy in having a number of parties crowded in the centre. The Liberals are experts at co-opting left language and framings during campaigns, and historically, we know they don't govern like that.

The United States had eight years of Barack Obama. He made it incredibly clear that he was a right-wing Democrat. He cited Ronald Reagan lovingly in every stump speech for the last six months of the presidential 2008 campaign. And he made it clear that he was going to be a business-friendly Democratic president, and that he was not going to rock the neoliberal boat. And he didn't.

Once you feel the desire to engage, think about what you're good at and what you can contribute. It's about breaking down the idea that there are activists and ordinary people.

One of the things that could be exciting about this next phase of Canadian politics is if we could maybe have co-leaders.

Film 'This Changes Everything' is not a sad story. It's not a slit-your-wrists climate film. It's a story about people who are making change happen.

Find an organization, shoot them an email, call them up, find them on Facebook and say "Hey, I want to volunteer." And that first step could lead to a whole life of engagement. It could be a pretty exciting ride.

I've always kind of hated films about climate change.
