Political geography
The Liberals have support in most parts of the riding. In the 2004 election, the strongest Liberal areas were in the Alta Vista neighbourhood. However, in the 2006 election, they lost some of this support, but it was gained from lower income areas such as Heron Gate. By 2008, the Liberals had gained much of their support back in Alta Vista.
The Conservatives have their strongest amount in the southern parts of the riding, especially in the community of Blossom Park and around the Macdonald-Cartier International Airport By 2006, the Conservatives had won the neighbourhood of Elmvale Acres, but this was lost in 2008. The New Democrats have only won one poll in recent memory, and that was a poll in Heron Gate in 2004.

History The district was created in 1987. 65.7% was from Ottawa—Carleton, 20.1% from Ottawa Centre and 14.2% from Ottawa—Vanier. At the time, it was bounded on the west by the Rideau River, on the north by the Queensway, on the east by the city limits at the time, and on the south by the following line (from west to east beginning at the Rideau River): Ottawa city limits, River Road, Limebank Road, Leitrim Road, Canadian Pacific Railway, Lester Road (allowance for a road between lots 10 and 11, Concession 3 in Gloucester Township, Albion Road, Walkley Road.
1996 Redistribution
Following the 1996 redistribution, the riding added the neighbourhood of Hunt Club Park from Carleton—Gloucester, by changing the southeastern boundary to the city limits at the time (from Walkley to Conroy).
2003 Redistribution
Following the 2003 redistribution, the riding's eastern boundary was changed to Highway 417 from the former city limits. The boundary would follow Highway 417 from the Rideau River until Hunt Club Road. This shift added in a small piece of territory that was in Ottawa—Vanier and Ottawa—Orléans riding.
2012 Redistribution
Only a minor change to the riding's boundaries occurred followed the 2012 redistribution of Canada's ridings. Ottawa South lost all of its territory south of Hunt Club Road and West of Riverside Drive. This area, which only had 27 people as of the Canada 2011 CensusPopulation corresponds to Census Block 3506148710 was transferred to the new riding of Carleton.
2022 Redistribution
The 2022 Federal Redistribution pushed the riding boundaries southward to encompass the growing neighbourhood of Findlay Creek, formerly part of the Carleton riding. It also took away the north-west corner of the riding. The area between the Rideau River and Bank Street in the east to the Railway Tracks to the south, encompassing the neighbourhoods of Riverside Park, Billings Bridge and Heron Park were moved to the Ottawa Centre riding. The new boundaries came into effect upon the calling of the 2025 Canadian federal election.

Incumbent Liberal MP David McGuinty faced a re-match against local businessman Eli Tannis of the Conservative Party. The NDP ran national security expert Huda Mukbil. McGuinty easily won re-election with a slightly reduced majority, while the NDP had its strongest federal result in the riding's history, besting its prior high-water mark in 2011.
2019 Incumbent MP David McGuinty ran for re-election, and was challenged by Conservative Eli Tannis, a Lebanese-Canadian entrepreneur, New Democrat Morgan Gay, a community organizer and Green Les Schram, a self employed consultant. Despite winning 5,000 fewer votes than he had four years earlier, he easily held off the challenge from his nearest (Conservative) rival, with more than double the latter's total.
2015 While the Liberals were the third party in Parliament, David McGuinty served as the Liberal Party's critic for Natural Resources (2011–2012), Industry (2013) and the Privy Council Office (2013–2015). He was easily re-elected in 2015 when the Liberals were swept into power. He defeated the Conservative candidate, Dev Balkissoon, a consulting firm owner by over 23,000 votes. Balkissoon was criticized during the campaign for missing an all-candidates debate. The NDP candidate was George Brown, a former Ottawa City councillor for Riverside Ward (1985–1994), and the Green candidate was John Redins, a disabilities rights activist.

2011
While in opposition, McGuinty was promoted to the position of the Official Opposition House leader. Once again, he faced and defeated Elie Salibi, the Conservative candidate. McGuinty was one of only 34 Liberals elected to the House of Commons in the election, and both he and Salibi saw a reduction in their percentage of votes. The NDP candidate, James McLaren, a teacher, had the second best (after 2021) performance for the NDP in riding history, despite a mid-campaign controversy regarding comments he made on Facebook.
2008
In opposition, McGuinty served as the Liberal Party's environment critic. He faced nominal opposition from three lesser-known candidates. The Conservative candidate was Elie Salibi, the director of international sales with Corel, who was born in Lebanon. The NDP candidate was Hijal De Sarkar, a Carleton University political science student of Bengali descent. The Green candidate was Qais Ghanem, a doctor, born in Yemen. Former Libertarian Party leader Jean-Serge Brisson also ran, as well as Al Gullon, the Progressive Canadian candidate. Facing lower turnout in the riding itself, as well as nationwide, and a strong lack of enthusiasm for the Liberal leader Stéphane Dion, McGuinty was able to increase his vote total, and his lead over his closest opponent, from the 2006 election. McGuinty just barely missed the 50% mark, but was nonetheless re-elected handily in Ottawa South.

2006
David McGuinty was re-elected after two years as a Liberal backbencher. The race was expected to be closer than 2004, which it was, as McGuinty faced a tough challenge from Conservative Allan Cutler. Cutler was the whistleblower in the Liberal Sponsorship Scandal which saw millions of dollars of public funds transferred to Liberal friendly firms in Quebec during the Chrétien era. The margin of victory between the liberal and his conservative challenger was closer than in 2004, but McGuinty eventually came out on top. Cutler himself was painted as a hypocrite as he would not address the issue of his nomination. Accusations started that 2004 candidate Alan Riddell was given $50,000 not to stand for nomination in the race. Riddell was also pushed aside in an earlier nomination race that saw former MP Barry Turner acclaimed, but would later drop out, forcing a new race. Running for the NDP was the Lebanese-born economist Henri Sader who faced a difficult challenge holding on to the votes that Monia Mazigh won in the previous election. Running again for Greens again was John Ford who failed to hold on to his votes, and running for the Progressive Canadian Party again was Brad Thomson who lost votes as well. Thomson had all but dropped out however, endorsing McGuinty. The Marijuana Party planned to run Tim Meehan, but he did not gain ballot access.
