When the Vancouver Canucks became an NHL expansion team in 1970, Robson moved to CKNW to announce the team's games; he was popularly known as the "Voice of the Canucks" for nearly three decades. For the first seven years, he usually worked alone. For road games, he broadcast the game without a colour commentator and provided the pre-game, intermission, and post-game shows. In 1977–78, he was joined by former BC Lions player and broadcaster Tom Larscheid. From 1983–84 to 1987–88, his broadcasting partner was ex-Canuck Garry Monahan. Larscheid rejoined him in 1988–89.
