A week after graduation, Rinaldo joined
CTV Television Network's news division, initially working as a junior secretary to Donald Cameron, director of news. She later advanced to production manager then research for
W5, as well as reporting for
CTV National News and
Canada AM. She became anchor for the newscasts on
Canada AM in 1980, making her the first woman in Canada to hold a full-time position as a national news anchor. During her broadcasting career she interviewed several top celebrities including
John Candy,
Gordon Lightfoot and
Bob Marley. In 1985 she became weekend anchor of
CTV National News, a post she has held ever since, except for a brief period from 1988 to 1991 during which she was co-anchor with
Tom Gibney of the local
World Beat News on the network's
Toronto affiliate
CFTO. Since longtime weekday anchor
Lloyd Robertson's retirement in 2011, Rinaldo served as substitute anchor for Robertson's successor,
Lisa LaFlamme, on the main weekday national newscast. Since 2009, she has been anchoring
CTV News Channel three weekday afternoons. As of 2010, she is also a co-host of
W5 and a contributing reporter. In 2023, she marked her 50th anniversary of working for CTV, with the network broadcasting a one-hour retrospective special about her career on May 12. In the same year, CTV launched a new early edition of
CTV National News, to air at 5:30 p.m. with Rinaldo as anchor. ==Personal life==
