Hillary Firestone, a key marketing and promotions force behind the success of Teletoon Canada, died Tuesday at Toronto’s Princess Margaret Hospital after a bout with ovarian cancer, her family said Thursday.

Firestone, a sister of veteran TV producer Jay Firestone, joined Teletoon in August 1997 as VP of network marketing and promotions to direct its branding efforts as the cartoon channel launched on the Canadian airwaves.

Before coming to Teletoon, she was a senior product manager at Kraft Canada. She left the cartoon channel in April 2005, handing over the post of marketing VP to Leslie Krueger.

A funeral service for Firestone was to be held on Thursday afternoon in Toronto, with interment to follow.

In her memory, the Hillary Firestone Ovarian Cancer Research Fund has been set up to support Princess Margaret Hospital.
