As a solo artist, Sibbles worked with Lloyd "Bullwackie" Barnes, Lloyd Parks, Sly & Robbie, Augustus Pablo, Bruce Cockburn, and Lee Perry, but primarily produced himself. Sibbles moved to Canada in 1973, where he married and remained for twenty years, and won a U-Know Award for best male vocalist in 1983, and a Juno Award for best reggae album in 1987. He left the Heptones in 1976, midway through a US tour. Also in Canada, he recorded an album for A&M and licensed several albums to Pete Weston's Micron label, including "Now" and "Strictly Roots". In 1990 he collaborated on the one-off single "Can't Repress the Cause", a plea for greater inclusion of hip hop music in the Canadian music scene, with Dance Appeal, a supergroup of Toronto-area musicians that included Devon, Maestro Fresh Wes, Dream Warriors, B-Kool, Michie Mee, Lillian Allen, Eria Fachin, HDV, Dionne, Thando Hyman, Carla Marshall, Messenjah, Jillian Mendez, Lorraine Scott, Lorraine Segato, Self Defense, Zama and Thyron Lee White.
