Dave Devall

In 2020, Devall was interviewed about his work on Definition for the GameTV documentary series The Search for Canada's Game Shows.

He appeared briefly at the end of longtime CTV anchor Christine Bentley's final broadcast on September 14, 2012.

Following retirement, Devall has made appearances in television commercials for local businesses, including an area Toyota dealership in 2010 and Loblaws in 2011. In July 2012, Devall appeared in a string of commercials for Shoppers Drug Mart.

He was also one of several retired longtime CFTO employees (including the more recent departures of Tom Gibney (2007) and Jim Junkin (2010)) who returned for a retrospective on the station's fiftieth anniversary on December 31, 2010.

David Devall (born 1931) is a Canadian retired broadcaster and meteorologist. He served as the chief forecaster at CFTO-TV in Toronto for more than 48 years beginning in 1961, and was recognized as having had the "longest career as a weather forecaster" by Guinness World Records and the World Records Academy upon his retirement on April 3, 2009. Devall was also a recipient of the RTNDA's lifetime achievement award in 2009.

Devall retired on April 3, 2009. Two days earlier, it had been announced that Devall had set the newly created Guinness World Record for the "longest career as a weather forecaster" at 48 years, 2 months, and 27 days. That record was surpassed by fellow Canadian broadcast weather forecaster Peter Coade in 2013.

Devall was made an honorary colonel of the Canadian Forces Squadron 436 at CFB Trenton in February 2007.

Devall's voice was heard across Canada as Jim Perry's announcer on many of his game shows, including Definition, Headline Hunters and Eye Bet, as well as in Ford television commercials on the popular Hockey Night in Canada program. In 1975, Devall was offered a hosting position with ABC's Good Morning America; he turned down the offer and remained with CFTO-TV. While at the station, he also served as a continuity announcer, voicing promos, bumpers, program intros and outros, station IDs and the nightly sign-off sequence, most famously backed by the ELO instrumental track "The Whale", and years earlier by Eric Gale's instrumental version of "Killing Me Softly with His Song".

While studying at Ryerson Institute of Technology's radio and television arts program, he also served in the Royal Canadian Air Force (RCAF) where part of his training centred on meteorology. In 1956, while still a student, he worked at CFPL-TV in London, Ontario; he then moved to Toronto radio station CFRB, where he stayed from 1957-1958. After graduating in 1958, he worked at CHEX-TV in Peterborough. When CFTO launched in 1961, Devall auditioned with 2,000 other hopefuls; he was one of six people hired as a broadcaster, and he started at the station on January 7 of the same year.
