The Greens roll out some big policy ideas and expect other parties to steal them

Among its members, it's a running joke: The Green Party of Canada comes up withthe big ideas and the other parties rip them off.

Many of those policies same-sex marriage, cannabis legalization, a carbon tax and a guaranteed basicincome have now come to define the national conversationand, in some cases, Canada's place in the world.

Kevin Bosch, who worked for almost 20 years with several Liberal leaders, said thatalthough theGreens seldom get credit for it, they're often the trailblazers in Canadian public policy.

"The other political parties look to what they are doing as [the Greens]put forth these trial balloons," said Bosch, who is now the vice-president of public affairs at Hill+Knowlton Strategies. "I think they are the vanguard in some areas."

The eight-month Green Party leadership race has given its contestants a chanceto thrash out new policypositions that could set thenational agenda for years to come.

CBC News: The House31:51What do the Green Party leadership candidates have to say?

During the month of September, CBC Radio's The House discussed leadership priorities with the eight contenders vying to helm the Green Party of Canada a race that comes to an end Oct. 3.

Former Green electioncampaign directorSonia Throuxsaid the race is producing a flurry of new ideas.

"Similar to the role the federal Green Party plays on the national landscape, a leadership race plays that same role for a party," saidThroux, now the co-executive director for the non-partisanLeadnow advocacy organization.

As online voting opens today, almost 35,000 registered members are getting a chance todecide which candidatewill help shape that policy. Here aresome of the ideas that could gain momentum and some perspectives on whether they might go mainstream.

A wealth cap

Several candidates have argued the wealthiest Canadians need to pay more. CandidatesDimitri LascarisandAmita Kuttnerhave gone so far as to propose a cap on the amount of moneya person can earn in Canada. Kuttner, who identifies as non-binary and uses the pronoun "they," said they would tax income in excess of $100 million at a rate of 100 per cent.

Bosch calls the idea extreme.

"It may have populist appeal," hesaid. "It probably would be seen as too radical for most voters."

Throuxsaid she alsoisn't sure that a hard cap has much runwaybutadded there's "fertile ground"for such a policy pitch in the electorate especially among young voters who want to see extreme incomeinequality addressed.

Both Bosch and Throux see a future for a wealth tax, a measure Justin Trudeau's Liberalspromised to adopt in the recentthrone speech. It's a policy the Greens adopted forthe 2019 election campaignas well.

Guaranteed livable income

All of the candidates have renewed their support for a guaranteed income,long a signature policy of the Greens. Throuxsaid she believes the idea has momentum now, in part due to the efforts of Greens.

"I'd say we are on the brink of a centrist federal government actually considering concepts similar to a basic income," she said. "I am now seeing members of [the Liberal Party]starting to speak to it. And I think that is a massive paradigm shift."

The Liberals are already transitioning millions of Canadians from their signature pandemic aid program, the Canada emergency response benefit (CERB), to new benefit programs. Some have comparedthese benefits to a guaranteed livable income.

But there are doubts about whether governments can afford these programs without racking up unsustainable levels of debt, Bosch said.

"A basic income has to make economic sense," Bosch said.

So far, only one leadership candidate former Ontario Liberal cabinet minister Glen Murray has costed out how a guaranteed income program couldbe deliveredby the federal governmentwithout increasing Ottawa's ballooning deficit even further.

Ending fossil fuel use

In the spring, outgoing Green Party leaderElizabeth Maygrabbed headlines by declaring that"oil is dead."

"My heart bleeds for people who believe the sector is going to come back. It's not," May told reporters. "Oil is dead."

Several Green leadership candidates haveseized on the idea and have vowed to phase out fossil fuels by 2040. Throux said that, if anything, the idea is fosteringimportant conversations among voters about the need for Canada to take radical steps to meet its climatecommitments.

"The awareness of how quickly we have to move in order to prevent catastrophic levels of climate change is rapidly approaching," she said.

Green Party Leader Elizabeth May says "oil is dead" and urges the government to invest into a low carbon economy, including renewable energy, following the COVID-19 pandemic.

Saying the era of big oil has come to an endis one thing, Bosch said, whilefinding affordable energy alternativesis something else. The Greens, he said,haven't explainedhow the party would transition Canadaaway from fossil fuels.

"Just saying that we are going to wipe out fossil fuel over night is not realistic," hesaid. "And you have to fill the energy mix with something else."

He said hecan't see how the Greens could adopt a policy of eradicating fossil fuel usewithout alsoconsidering nuclear power whichthe party has traditionally opposed.

Border carbon tax

Leadershipcandidate Annamie Paul is urging herparty to consider anew measure:slapping a tariff on imports from countries with lax environmental policies.

The tactic is being considered by the European Union, the world's second-largest economic bloc. The idea is toensure domesticbusinesses stay competitive bypenalizing countries that maintaina competitive advantageby not doing their part to reduce greenhouse gas emissions, Paul said. The policy is also intended to discouragebusinesses fromrelocating to jurisdictions with weaker environmental regulation.

"We are a party of innovation," Paul said. "This is a policy that is complementary to our existing green member policy."

Carbon border adjustments, Throux said, would "level the playing field" for Canadian businesses that abide by stringent regulations.

ButBoschsaid the idea isn't well thought-out and could complicate Canada's relationship with theTrump administration,whichpulled the U.S.out of the Paris climate agreement.

"With the current U.S. administration, you might be just creating a tariff war," he said. "Something that Donald Trump has shown he is not adverse at all to getting involved in."
