# Ottawa South (provincial electoral district)

Ottawa South (French: Ottawa-Sud) is a provincial electoral district (riding) in the Canadian province of Ontario, in the city of Ottawa.

## History

The district was created in 1925 from part of Ottawa West. Prior to the 1999 election, the provincial district did not have the same borders as the federal district.
Prior to the 1967 redistribution, the riding shared no common area with the present riding. Present day Ottawa South could be found in the riding of Russell prior to 1967.
After having been firmly conservative for the first 60 years, it has been in the hands of the Liberals without interruption since 1987. From 1987 to 2013, it was held by two generations of the McGuinty family–father Dalton Sr. from 1987 to 1990 and son Dalton Jr. from 1990 to 2013.45°21′N 75°38′W﻿ / ﻿45.350°N 75.633°W﻿ / 45.350; -75.633
