Early life
Rubinek was born in Föhrenwald, a displaced-persons camp in Allied-occupied Germany, in 1948. His parents, Frania and Israel Rubinek, were both Yiddish-speaking Polish Jews who were hidden by Polish farmers for over two years during World War II. The family emigrated to Canada the same year Rubinek was born. He attended Camp B'nai Brith in Sainte-Agathe-des-Monts, Quebec.

Rubinek wrote the book So Many Miracles (Penguin Canada) on his parents' experiences in the war.
