Gray served as a Councillor for both the city of Oshawa and the
Regional Municipality of Durham for nine years prior to being elected as mayor in November 2003. In 2003 he ran for mayor and defeated four-term incumbent
Nancy Diamond leading with 40% of the vote in a five candidate race. Gray was re-elected for a second term in 2006 but was defeated in 2010 by local businessman,
John Henry. In March 2011, Gray considered an offer to run in the
2011 federal election. He cited family considerations in his decision. In July 2018, Gray decided to return to municipal politics and announced his candidacy to become a city councillor for
Oshawa. On October 22, 2018, Gray was elected to Oshawa City Council - Ward 5 - in a handily won victory, securing almost 60% of the votes cast. Gray, along with the other successful candidates in the 2018 Oshawa Municipal Election, were sworn in on December 3, 2018. On October 24, 2022, Gray was re-elected to Oshawa City Council for Ward 5. ==References==
