Progressive Champion Avi Lewis Wins Leadership Race for Canada’s NDP, Vowing Left Party Will Come ‘Roaring Back’

Progressive activist Avi Lewis is pledging to bring Canada's New Democratic Party "out of the wilderness" after being decisively elected as its new leader on Sunday on the back of an ambitious, affordability-focused agenda aimed at winning back working-class voters.

Lewis, the grandson of one of the NDP's cofounders, cruised to a resounding victory, earning 56% of the vote to take over leadership of the long-ailing left-wing party, which has bled members in recent years to both Prime Minister Mark Carney's Liberals and Pierre Poilievre's Conservatives.

He was introduced at Sunday's Winnipeg convention by his wife, the acclaimed author and activist Naomi Klein, who said her husband's victory was an invitation for Canadians to “dream big once again" and renew the fight against corporate greed at a time when more than half of the population says they struggle to afford basic necessities.

Lewis has proposed a sweeping agenda of “public options” aimed at combating Canada’s affordability crisis, including publicly owned grocery stores and banks to compete with price-gouging corporate monopolies.

A scion of the party that helped to build Canada’s universal healthcare system—which covers hospital and physician care—he’s called for it to be expanded into a “head-to-toe” care system that guarantees dental, drugs, vision, hearing, and mental health services for all Canadians.

In order to pay for these programs and others—including public housing, green energy investment, and subsidized phone and internet plans—Lewis has campaigned to pass a wealth tax on the richest 1% of Canadians, who own nearly $1.25 trillion, almost as much as the bottom 80% of Canadians, according to a recent report by Oxfam Canada.

"This country is awash in wealth. We can have nice things," Lewis asserted to a raucous crowd during his acceptance speech. "Banks made $70 billion in profits last year alone. Oil companies are expecting a new windfall in the tens of billions. Grocery baron Galen Weston alone is worth $20 billion."

During his campaign, Lewis railed against tax cuts for wealthy Canadians passed by the Liberal government, which are projected to cost the government nearly $76 billion over five years and slash an estimated 57,000 public-sector jobs by 2028.

"It is time, far past time, to properly tax the billionaires and corporations that have been riding a tidal wave of profit," Lewis said.

While he acknowledged that Carney is still largely popular in Canada, in large part due to his fiery denunciations of US President Donald Trump's tariff war and threats to annex Canada, Lewis argued that the prime minister's revulsion toward Trumpism is only skin-deep.

"I think when you connect the dots, his moves do not add up to the vision that Canadians truly want and deserve in this perilous moment," he said. "Half a trillion dollars in a decade for weapons to make Canada a major arms exporter in a war-torn world. Slashing our cherished public services, sweeping aside indigenous rights... No regulations on AI and pipelines."

"In the last federal election, Canadians voted to say no to Trump and Trumpism," Lewis said. "What they're getting instead is our government following the US into a future of wars, fossil fuels, austerity, and job-killing generative AI."

Lewis will face a difficult task ahead in rebuilding the NDP from a disastrous loss of support under its previous leader, Jagmeet Singh, who stepped down from his post after the party suffered the worst defeat in its history during last April’s elections, dropping to just seven seats in Parliament—not even enough to be considered a “recognized” party.

The role of NDP leader is the highest office Lewis has held in his life, having run two failed campaigns for parliament in his native Vancouver in 2021 and 2025.

Though NDP currently sits at a distant third, with only about 7% support according to an Abacus poll from March, other polls show that their positions, including a wealth tax and expanding federal health coverage, are popular with the vast majority of voters across party lines.

Other polls show that Canadians, especially those with low incomes, increasingly view affordability and inequality as pressing issues, especially as Trump's war against Iran has caused global energy shortages and price hikes.

"The NDP is coming back because we know that a thriving world is possible, and we know who is standing in our way, and there are way more of us than there are of them," Lewis said. "The NDP will start winning again because we will become that beacon to the 99%."
