The flag of Toronto, Ontario, Canada, was originally designed in 1974 by Renato De Santis, a 21-year-old graphic design student at George Brown College. The design was the winner of a 1974 competition held by the City of Toronto Flag Design Committee. The previous flag had consisted of the city's coat of arms on a white and blue background, which was considered to be overly simplistic by then mayor William Dennison.When several municipalities in the Toronto area were in the process of amalgamating, the Toronto City Council launched a competition in 1997 for new designs from the public, but the council did not approve any of the public submissions. During the review process, De Santis suggested minor modifications to his original 1974 flag design. This revised version beat out a design recommended by then councillor Brad Duguid in a November 1999 council vote to become the current flag.
