As a journalism student in the 1960s, he wrote his master"s thesis on the then-emerging phenomenon of women in politics. His first job as a journalist was with a local radio station in Oakville, Ontario, where he began working in 1967. Fisher worked for Canadian Broadcasting Company Television in the 1980s as a Queen"s Park reporter and host of Dateline Ontario for CBLT, until taking a job with the Global Television Network in 1988.
While at Global, he hosted the weekend newsmagazine Focus Ontario on CIII in the 1980s and 1990s.
He was also the network"s Queen"s Park bureau chief, and a sometime anchor of the station"s 6 p.m. newscasts on weekends and its 11 p.m. weekday newscasts. He served on the journalist"s panel for the election debates in the 1987 provincial election as a representative of the Canadian Broadcasting Company, and in the provincial elections of 1990, 1995 and 1999 for Global.
In the 1999 debate, his final question to Ontario Liberal Party leader Dalton McGuinty was perceived by some Liberals as unfair. As well, he appeared as an analyst for the network"s coverage of the federal elections in 1988, 1993 and 1997.
He was fired from Global in 2000 after criticizing what he perceived as the network"s shift toward infotainment reporting.
He returned to Canadian Broadcasting Company Radio shortly thereafter. Fisher has taught journalism law and ethics at Centennial College and radio and television news at Ryerson University. In 2015, Fisher announced his retirement from journalism.
His final day at Canadian Broadcasting Company Radio was July 23.
