He was born at the Ottawa Civic Hospital in Ottawa, Ontario, and named after his paternal grandfather, Charles-Émile. Trudeau was known to family and friends as Miche, a nickname given to him as a four-month-old by Fidel Castro when he accompanied his father and mother to Cuba in 1976, and he later started going by Mike. Trudeau lived his early life in Ottawa and later Montreal upon his father's retirement from politics in 1984, where he was a classmate of Sophie Grégoire. During their summer breaks, Michel and his brothers attended Camp Ahmek on Canoe Lake in Algonquin Provincial Park where he would later work as a camp counsellor. He studied at Collège Jean-de-Brébeuf before attending Dalhousie University to study microbiology. When talking about her sons each having distinctly different personalities in an interview in 1977, Margaret Trudeau said, "Justin, 6, is a prince — a very good little boy. Sasha (Alexandre), born Christmas Day, 1973, is a bit of a revolutionary, very determined and strong-willed. Miche (Michel) is a happy, well-adjusted child, who combined the best traits of both brothers."
