The riding was first created in 1966 from parts of what are now Oshawa and Whitby, and was very competitive for its first 2 elections. However, the riding quickly became a New Democratic Party (NDP) stronghold during the tenure of Ed Broadbent and the riding continued to be that way until the early 1990s. During this period, the boundaries were changed twice, in 1976 and 1987, with the riding now consisting of southern and central Oshawa.

In the early 1990s, the unpopularity of both the NDP and the Progressive Conservatives (PCs) caused the Liberals to win the seat throughout the 1990s. After the PCs and the Reform Party merged to form the Conservative Party, the NDP tried to take it back by nominating a well-known labour leader but lost by a close margin. In the elections following 2004, the Conservatives continued to increase their share of the vote, as did the NDP to a lesser extent, at the expense of the Liberals. Despite large Liberal gains in 2015, the Conservatives continued to hold this riding. It has been represented by Conservative Colin Carrie since 2004.

Riding profile

The riding currently consists of the City of Oshawa south of Taunton Road.^[2]

In 2016, the riding's population was 126,764, an increase of 0.8% compared to the population in 2011. In 2015, the median income in the riding was $32,567, slightly below the Ontario average and up from 30,773 in 2010.^[3][4] The riding has a much lower proportion of visible minorities compared to the rest of the province. In 2016, 11.9% of the riding's population was part of a visible minority, compared to the provincial average of 29.3%.^[3] In 2011, about 67% of the riding's population was Christian, which was slightly above the Ontario average. Having no religious affiliation was also slightly above the Ontario average, with about 30% of people in the riding having no affiliation.^[4][5] The riding had historically been dominated by a working-class electorate, but the loss of auto industry jobs in the area since the 1980s has lessened the influence of the working class.^[6]

History

1966-1990: Oshawa—Whitby as a marginal seat and dominance of the NDP

The riding was first created in 1966 with the Town of Whitby, the City of Oshawa, and part of Whitby Township, which were previously part of the riding of Ontario. In 1967, its name was changed to "Oshawa—Whitby."^[7][8] In the Ontario riding, the previous election was competitive, with the PCs, Liberals, and NDP all being within about 6500 votes (10%) of each other.^[9] In 1968, the election was very close. There were over 45,000 votes cast and all 3 candidates were within 325 votes of each other. NDP candidate Ed Broadbent won, beating PC Michael Starr, who won the previous election in the riding of Ontario, by 15 votes.^[9][10] Broadbent and Starr once again ran against each other in the 1972 election. It was also a close race, with Broadbent beating Starr by 824 votes.^[10]

In the 1974 election, Broadbent had increased his lead to 11,000 votes, receiving almost as many votes as the Liberal and PC candidates combined at the same time as prominent New Democrats such as David Lewis lost their seats.^[11][9] Shortly after, Broadbent was appointed Parliamentary leader of the NDP then was elected leader of the NDP the following year.^[12][13] In 1976, the riding was modified to now only include the City of Oshawa and its name was changed back to "Oshawa."^[8][14] In 1979, a writer for Maclean's described Broadbent's re-election chances as "considerably better" than his chances in 1968.^[11] He was re-elected by a margin similar to his previous victory, though over a PC rather than a Liberal.^[9]

By this point, the riding was an NDP stronghold and they continued to win elections by large margins, increasing their margin of victory to 12,000 votes in 1980.^[9][10] Shortly afterward, Prime Minister Pierre Trudeau invited Broadbent to join his cabinet, who rejected his offer.^[15] In 1984, Broadbent held on to the seat by a margin of 2000 votes despite the PCs' national landslide victory.^[9][10] In 1986, the riding was modified to exclude the area north of Rossland Road.^[14] In 1988, Broadbent would increase his margin of victory to about 4,400 votes over the PCs.^[9]

In 1989, Broadbent resigned as NDP leader and announced his retirement as MP later that year. He left parliament on December 31, 1989.^[13][16][17] By mid-1990, before the by-election, the government of Prime Minister Brian Mulroney was very unpopular.^[18] The PCs' vote share dropped from 33.8% to 6.4% while the NDP increased their vote share slightly. The Liberals increased their vote share to 34.4%.^[19]

1991-2002: The NDP's fall and the Liberals' success

 

Map of the riding from 1996 to 2003

By the time the 1993 election campaign started, the NDP was also very unpopular.^[20] Despite the Liberals' vote share in the riding not increasing much compared to in 1990, Liberal candidate Ivan Grose won as part of the Liberals' near-sweep of Ontario.^[19][21] In 1996, the riding was once again modified. It would lose the part of the riding east of Harmony Road and north of King Street (former Highway 2), but it would gain the area west of Ritson Road between Rossland Road and Taunton Road.^[14] The 1993 result for each party did not vary more than 1.2% when redistributed to the new area of the riding.^[19][22]

In 1997, the PCs and the NDP rebounded slightly at the expense of the Liberals and the Reform Party and Grose was re-elected by a slightly smaller margin.^[22] In 2000, the Liberals increased their vote share and their margin of victory by about 5%, mostly at the expense of the NDP.^[22]

In 2003, the riding was expanded. Initially, the district would consist of the area of Oshawa south of Rossland Road as well as the area east of Ritson Road south of Taunton Road.^[23] However, area MP Judy Longfield objected, by which point the proposed boundaries had changed to south of Rossland and south of Taunton west of Ritson. Longfield proposed, citing support from MP Ivan Grose and Oshawa City Council, that the district be changed from the previous version to not include the area west of Simcoe Street north of Rossland Road and the Oshawa Creek north of former Highway 2, but include the area east of Simcoe Street up to Winchester Road. A new Whitby—Oshawa riding would cover the rest of Oshawa. The proposal was implemented and the redistributed result showed minimal change.^{[22][24][25][26]}

2004-2011: The Conservatives take the riding

In 2004, there was some infighting in the Liberal Party. Grose lost the Liberal nomination for that year's election. It was instead won by Louise Parks.^{[citation needed]} The NDP nominated Sid Ryan, a well-known labour leader.^[6] That year's election was very close, with Ryan coming within 500 votes of Conservative candidate Colin Carrie and Liberal candidate Louise Parks was within 1400 votes of Carrie.^[27] In the 2006 election, Parks, Ryan, and Carrie ran again. During the 2006 campaign, a writer for The Globe and Mail considered it to be a riding to watch.^[28] The NDP increased their share of the vote, but the Conservatives increased their vote share even more. These gains were at the expense of the Liberals, likely due to the recent layoffs at the General Motors Oshawa plant.^[27][28][29]

The Conservatives would once again increase their vote percentage in the 2008 election and by a higher amount than the NDP, at the expense of the Liberals. The Conservatives now had 41% of the vote, compared to the NDP's 34%.^[29][30] In 2011, a writer for the Toronto Star said that the increasing margins of victory for the Conservative Party over the NDP reflected the transformation of Oshawa from a working-class centre of the auto industry to another Toronto suburb.^[6] In the run-up to that year's election, a writer for the National Post considered it to be a potential NDP pickup. The NDP had nominated another union leader, Chris Buckley, president of a local branch of the Canadian Auto Workers union.^[31] Despite the NDP's rise nationally, the Conservatives still increased their vote share more than them, now having a majority of the vote in the riding.^[30][32]

2012-present: Nearly being split and continued Tory success

During the 2012 redistribution, the riding was originally going to be split into 2 ridings. South of former Highway 2, it would be part of a new riding called "Oshawa—Bowmanville" and the part north of former Highway 2 would be part of the riding of "Oshawa—Durham."^[33] During the public hearings, there was opposition to the new boundaries and the commission ended up revising the boundaries to consist of the area of Oshawa south of Taunton Road, despite the fact that the population of the district was now almost 20% above the provincial quota.^[34] MPs Erin O'Toole and Colin Carrie later objected, requesting that as much of Oshawa as possible be kept within one electoral district, adding 2 campuses. The commission rejected this.^[35][36]

In the 2015 election, despite the large gains by the Liberals under Justin Trudeau, who now had 27% of the vote in the riding, Carrie was re-elected with 38% of the vote. The NDP did fall, but not as much as the Conservatives to 31%.^[37] Shortly after the election, Carrie was appointed to be the Conservatives' Deputy Health Critic.^[38] In April 2016, Carrie was promoted to Health Critic.^[39] By the 2019 election, Carrie had become the Shadow Cabinet Secretary for Canada-US relations and Economic Development in Southern Ontario.^[40]

In April 2019, Forum Research conducted a poll in the riding showing a larger Conservative lead and a large NDP decline.^[10] In the 2019 election, Carrie was re-elected again, increasing his vote share slightly while the Liberal and NDP candidates lost 2-4% of the vote each.^[41][42] After the election, Carrie retained his previously held critic roles.^[43]
