Brown was first elected to the York Borough Council in
1969, defeating three challengers in the city's fourth ward, and was re-elected in
1972. He campaigned for Mayor of York in
1974 and
1976, but lost to
Philip White both times. He also ran for a seat in the
Legislative Assembly of Ontario in
1977 as a candidate of the
Progressive Conservative Party, finishing second against
New Democratic Party incumbent
Tony Grande in
Oakwood. In January 1978, he was appointed by
Premier Bill Davis to the Metro Toronto and Region Conservation Authority. After a four-year absence, Brown returned to York Council in
1978, winning election to the city's
Board of Control. The position also gave him an automatic place on the
Metropolitan Toronto Council. He was re-elected in
1980,
1982 and
1985, and served as York's budget chief for this entire period. Brown sought to replace
Paul Godfrey as chair of Metro Council in 1984, but finished second against
Dennis Flynn of
Etobicoke. He campaigned for a position on the police board later in the year, but lost to
Art Eggleton. Brown was named head of Metro's social service committee in 1985 and served as a member of the
Toronto Transit Commission. He was elected to succeed
Alan Tonks as mayor of York in
1988, defeating former MPP Tony Grande by a significant margin. Brown highlighted his record of financial accountability and suggested that Grande did not have significant municipal experience to govern the city. In 1990, Brown endorsed a controversial plan to sell part of
Fairbank Park to a company run by Toronto-area developer Lou Charles. The details of the sale provoked charges of political corruption, setting in motion a series of events that eventually led to the arrest and conviction of Charles and some of his political allies. Metro police investigated Brown's role in the sale but did not lay charges. In July 1991, Brown reversed his earlier position and helped council defeat the proposed sale. Several media reports from this period depicted him as unable to maintain order over an increasingly dysfunctional council. Brown was re-elected to the mayor's office in
1991 over his old rival Philip White. He helped ensure passage of a compromise Market Value Assessment tax plan for Metro Toronto in 1992, although this plan was later overturned by the provincial government of
Bob Rae. Brown was defeated in
1994 by
Frances Nunziata, who had spearheaded opposition to the Fairbank sale in 1990. The campaign centred on leadership issue: Brown pointed to his tenure in office, while Nunziata argued that he did not show decisive leadership during the controversy. The contest was marked by open animosity between the candidates, and Brown refused to travel to Nunziata's headquarters on election night to concede defeat. Ideologically, Brown was described as a "moderate Tory", an "old-fashioned conservative", and a "very Red Tory". He endorsed
David Miller in his campaigns for
Mayor of Toronto. ==Later life==
