Cranston was born in
Hamilton, Ontario, in 1949 and grew up in
Kirkland Lake. When he was 11, his family moved to suburban
Montreal. Growing up, Cranston had an uneasy relationship with his family, especially his mother, who was a painter and who he said had a domineering and self-centred personality. He later compared his childhood to "being in jail"; in school he had the habit of asking provocative questions that made his teachers think he was being disruptive. After high school, Cranston attended the
École des beaux-arts de Montréal. By his third year, he became restless with his studies. One of his teachers suggested that there was nothing more he could learn at the school, so Cranston set out at that point to establish himself as a professional artist. In 1976, he teamed up with personal manager Elva Oglanby to write his first book,
Toller, a mixture of autobiography, sketches, poems, paintings, humour and tongue-in-cheek observations. It reached number two in the Canadian non-fiction charts. Cranston co-wrote the autobiographical
Zero (1997) with Martha Lowder Kimball, and a second volume,
When Hell Freezes Over: Should I Bring My Skates? (2000), also with Kimball. Though he described a sexual tryst between himself and
Ondrej Nepela in the second book as well as affairs with women, in his books he presents himself as having lived without forming strong romantic or emotional attachments. ==Artistic career==
