Doug Holyday is a Toronto city councillor, representing Ward 3 in Etobicoke Centre. He was the last mayor of the former city of Etobicoke, which was merged into Toronto subsequent to the 1997 municipal elections. He was also a member of the Metropolitan Toronto Council from 1994 to 1997, and previously served as an Etobicoke councillor for nine years. One of Toronto council's staunchest conservatives, he is noted for his fiscal conservatism and tendency to oppose public spending measures.

Holyday has lived his entire life in Etobicoke, and was a successful businessman before entering political life.

In addition to his fiscal conservatism, Holyday has also supported conservative policies in other fields. He has proposed removing the homeless from Nathan Phillips Square, and was the only member of council not to vote for a resolution describing homeless as a national disaster. He once castigated plans to close certain streets in downtown Toronto for a "car-free day" as "catastrophic". Holyday also supports reducing the number of councillors, and voted against childcare subsidies. In 2003, he was named Toronto's worst councillor by the left-leaning Now Magazine.

Holyday ran for the Legislative Assembly of Ontario as a Progressive Conservative candidate in the 1987 provincial election, but lost to Liberal Linda DeBourdais by over 6,000 votes. He was asked to run for the Tories in the 2003 provincial election, but declined.

Holyday did not face serious opposition in the 2003 Toronto election, and was re-elected without difficulty.
