Cecile Klein was born as Cecile Edith Efros in Montreal, Quebec, Canada on 15 June 1907 to Polish-born Jewish parents Louis Efros (1881–1950) and Rebecca Pearson Efros (1887–1965). In 1923, Klein began attending secretarial school and taught herself typing. Klein began working for a lawyer’s office and later for an early form of HR at RCA Victor. During the Great Depression, Klein managed to find her uncles a position at RCA Victor.

Klein later moved to Westmount, Quebec where she married Israeli-born Erwin Klein (1905–1999) on 5 June 1932. The couple had three children: Harriet, Arnold, and Louise. Klein had a grandmother who lived to 103, still alive at the time she married Erwin, alongside Klein’s centenarian great-aunt.
