Family Connections
Stephen Lewis was part of an illustrious family of left-wing political activists and commentators. His grandfather, Moishe Lewis, was a labour activist in Russia and Montreal. Stephen’s father, David Lewis, served as national secretary of the Co-operative Commonwealth Federation (CCF). He was also leader of the federal NDP from 1971 to 1975.
Stephen’s wife, Michelle Landsberg, was a long-time columnist with the Toronto Star. They had three children together: daughters Ilana and Jenny and son Avi. Ilana Landsberg-Lewis became a labour and human rights lawyer. Avi Lewis became a high-profile journalist, TV personality and filmmaker. He is married to best-selling author, activist and filmmaker Naomi Klein.
Following in his paternal footsteps, Avi Lewis was elected leader of the federal NDP on 29 March 2026. Stephen Lewis died two days later after a long battle with cancer.
Early Life and Education
Born on Armistice Day (now Remembrance Day) in 1937, Stephen Lewis was given the Hebrew name Sholem, which means “peace.” He was born and raised in Ottawa but moved with his family to Toronto in 1950. He began studying at the University of Toronto in 1956. As a member of the Hart House debating team, he debated Massachusetts senator and future US president John F. Kennedy in November 1957.
Lewis spent his third year of university on exchange at the University of British Columbia. He returned to Toronto for his final year but didn’t graduate. He then entered the law schools at the University of Toronto and UBC but dropped out of both. (Lewis later joked that all his university degrees were honorary.)
While working as a clerk at the Socialist International in the 1960s, Lewis attended a conference in Ghana. He then spent a year travelling and teaching English in Africa.
Career in Politics
Stephen Lewis was urged to return to Canada by federal NDP leader Tommy Douglas. Lewis worked as director of organization for the federal NDP from 1961 to 1962. He was then elected as a member of the Ontario legislature for Scarborough West from 1963 to 1978.
Lewis became leader of the Ontario NDP in 1970. He was active in demanding the 1972 disbandment of the Waffle, a left-wing NDP faction. Lewis’s greatest electoral success occurred in 1975 when the NDP became the Official Opposition. A year after the NDP's electoral setback in 1977, Lewis resigned as leader. He then became a media commentator, lecturer and labour arbitrator.
