Miron was born in 1929 in Cornwall, Ontario Canada. He played hockey growing up and played in the minor leagues. Miron has said he wasn't a strong enough skater to make it in the NHL. While working in a Canadian plant during World War II, Miron was in a mustard gas accident. The accident left much of his body covered in mustard acid, which severely burned him and left him in a hospital for months. Miron met his wife Rowena in the 1950s. Rowena died in 2004. They have two children and four grandchildren; their son Monte Miron served as commissioner of the CHL from 1992-2000.
