Jasmin's journalistic career began at Radio-Canada's world service at the end of the 1940s. It was there she met future Quebec premier René Lévesque with whom she would go on to co-host the radio program Carrefour. In 1953, Jasmin entered Radio-Canada's television news service where she made a name for herself with such programs as Reportages and Conférence de presse. All the while, Jasmin continued to take to the streets, listening to the people in order to denounce injustices. She was a founding member of the Mouvement laïque de langue française ("The Francophone Secular Movement").
