She spent much of her life married to her
Wayne & Shuster castmate Ben Lennick. They had three children: Michael, a television producer, Julie, an actress who performs regularly with the Toronto Civic Light-Opera Co., and David, a radio host. The Lennicks were
Jewish, and the scheduling of the troupe's breakthrough appearance on
The Ed Sullivan Show forced the Lennicks to postpone David's
bar mitzvah. In the early 1960s Ben and Sylvia, along with partner Jack Merigold, revived Belmont Theatre Productions and produced several seasons of well-received dramas, comedies and musicals. In the mid-1970s Ben and Sylvia, along with Jack Merigold and new cast member Allan Price, took the concept one crucial step further with the creation of their new company Theatre in the Home, bringing professional theatre productions to shut-ins in retirement communities and private residences. In 1983, Lennick and
Jan Rubeš appeared as Fräulein Schneider and Herr Schultz in a Toronto production of
Cabaret. In a 2008 interview with the
Toronto Star to mark the 50th anniversary of the Wayne & Shuster troupe's historic performance on
The Ed Sullivan Show, Lennick stated that when she first read the script, she hadn't thought that "I told him, Julie! Don't go!" would be the sketch's biggest laugh line: "I thought I was going to kill them when I said, `It's the Ides of March, already.'" ==Death==
