Schreiner said he has talked to Cullen about electoral reform and has offered the Green Party’s backing of the MP's proposal.

“This shouldn’t be about partisanship,” he said. “We want to keep up the momentum.”

Cullen said during the nearly two-hour event that he has invited local Liberal MPs, including Bob Bratina, to his town halls. So far none have appeared.

“It wasn’t just Justin Trudeau who campaigned on this promise,” said Cullen. “Anybody who ran on this promise as far as I’m concerned they made the promise. If they are willing to break it, then they have to be willing to stand up in front of their constituents.”

Bratina said in an email statement that he already held a town-hall meeting last year on electoral reform in Stoney Creek and received “minimal response or interest. Only a few showed up.”

“It should be obvious to Canadians where our priorities lie right now,” said Bratina.

Cullen is a proponent of eliminating the current first-past-the-post system, where parties win majority governments with a minority of voters. He supports a single transferable vote system.

“It’s not like it’s rocket science,” said Cullen. “We have dozens and dozens and dozens of countries doing it for decades with stable, strong governments that make progressive legislation.”

Cullen said minority governments have proved benefit to Canadians. Under minority governments, health care, social insurance, unemployment insurance and even the creation of Canada’s flag were all introduced and are now part of the country’s institutional landscape.

He said the fundamental difference with minority governments is every MP has inherent power and “has to be spoken to.” In a majority government, the power remains with the prime minister and his cabinet, he said.

Cullen isn’t a fan of holding a referendum. He points to Ontario’s 2007 failed referendum on changing its electoral system with its confusing question. What happens in referendums, he said, is misinformation is spread and it’s not clear to people what they are voting for.

Cullen said despite what the Liberals are saying that Canadians are not interested in electoral reform, his town meetings have proved them wrong.

“People are very much hopeful of this,” he said. “It’s a basic requirement of the (MP) job. If you won’t stand in front of the people you work for, then who do you work for?”
