Avi Lewis has spent much of his professional life at the intersection of journalism, political activism, environmental advocacy and progressive politics. Long before becoming a party leader, he was familiar to Canadians as a broadcaster and documentary filmmaker who frequently explored questions involving inequality, labour, climate change and political power. In March 2026, that career took a major turn when Lewis was elected leader of Canada’s federal New Democratic Party, bringing him directly into the leadership of a party with deep connections to his own family’s political history.
Born in Toronto in 1967, Lewis grew up in a family with an unusually strong connection to Canadian public life. His grandfather, David Lewis, served as leader of the federal NDP, while his father, Stephen Lewis, led the Ontario NDP before becoming a diplomat and prominent humanitarian advocate. His mother, Michele Landsberg, built a distinguished career as a journalist and social activist. Politics, journalism and social issues were therefore part of Lewis’s environment from an early age, although his own path initially took him toward broadcasting rather than elected office.
Lewis graduated from the University of Toronto and developed a television career during the 1990s. One of his early prominent roles was hosting The NewMusic, where he combined popular culture with political and social reporting. He subsequently became particularly well known for hosting CBC Newsworld’s counterSpin, a current-affairs program built around debate. Lewis presided over hundreds of discussions, developing a public identity as an interviewer comfortable with ideological disagreement and politically contentious subjects.
His career later expanded beyond Canadian broadcasting. Lewis worked on programs for CBC and Al Jazeera English and increasingly became involved in documentary filmmaking. One of his most important creative partnerships was with author and activist Naomi Klein, his wife. Lewis directed The Take, a documentary examining Argentine workers who occupied and restarted abandoned factories following the country’s economic crisis. He later directed This Changes Everything, inspired by Klein’s work on climate change and capitalism. Both projects reflected his longstanding interest in economic structures, environmental questions and grassroots political movements.
Climate policy became particularly central to Lewis’s public work. He was involved with the Leap Manifesto, launched in 2015, which proposed a rapid transition away from fossil fuels alongside broader economic and social reforms. The initiative attracted significant support from environmental and progressive activists but also generated disagreements within the NDP, particularly in regions where resource industries play a major economic role.
Lewis eventually attempted to move from political advocacy into electoral politics. He ran as an NDP candidate in the federal elections of 2021 and 2025 but was unsuccessful on both occasions. Those defeats meant that, even as his national political profile grew, he had never actually held elected office.
The situation changed dramatically after the NDP began searching for new leadership. Lewis entered the party’s 2026 leadership contest with a platform emphasizing economic inequality, public services, housing and aggressive climate action. His proposals included major public housing construction, expansion of publicly funded healthcare services, increased taxation of extreme wealth and new public alternatives in sectors such as telecommunications and pharmaceuticals.
On March 29, 2026, Lewis won the NDP leadership election on the first ballot with just over 56 percent of the vote. His victory made him leader of the same federal party once led by his grandfather, but it also created an unusual political situation: Lewis became federal NDP leader without holding a seat in Parliament and without having previously held elected office.
His leadership immediately highlighted some of the difficult questions facing Canada’s political left. Lewis’s opposition to new fossil-fuel development generated disagreement with some provincial New Democrats, particularly in Alberta and Saskatchewan, where energy policy carries enormous economic and political significance. Those tensions illustrate one of the central challenges of his leadership: combining ambitious national climate policies with the economic realities of regions heavily dependent on resource industries.
Avi Lewis therefore enters this stage of his career with a background very different from that of most Canadian party leaders. He has been a journalist, television host, documentary filmmaker, university educator and activist rather than a career parliamentarian. Whether that unconventional background becomes an advantage or a limitation will depend on his ability to transform years of advocacy into an electoral strategy capable of expanding the NDP’s support.
His story is also a remarkable example of political continuity across generations. Yet Lewis has attempted to establish an identity that is not simply inherited from his famous family. His focus on climate change, wealth inequality and contemporary economic insecurity reflects political debates very different from those his grandfather confronted decades earlier. His leadership of the NDP will ultimately be judged by whether he can translate those ideas into a broader political coalition and rebuild the party’s influence in Canadian federal politics.
