The '''2018 Ontario general election''' was held on June 7, 2018, to elect the 124 members of the [[42nd Parliament of Ontario]].<ref name="torstar elxn set jun 2018">{{cite news|last1=Ferguson|first1=Rob|title=Ontario moves election date to June 7, 2018|url=https://www.thestar.com/news/queenspark/2016/10/19/ontario-moves-election-date-to-june-7-2018.html|access-date=October 31, 2016|work=[[Toronto Star]]|date=October 19, 2016|archive-date=May 7, 2021|archive-url=https://web.archive.org/web/20210507171737/https://www.thestar.com/news/queenspark/2016/10/19/ontario-moves-election-date-to-june-7-2018.html|url-status=live}}</ref> The [[Progressive Conservative Party of Ontario]], led by [[Doug Ford Jr.|Doug Ford]], won 76 of the 124 seats in the legislature and formed a majority government. The [[Ontario New Democratic Party]], led by [[Andrea Horwath]], formed the Official Opposition. The [[Ontario Liberal Party]], led by incumbent Premier [[Kathleen Wynne]], lost [[official party status]] in recording both the worst result in the party's 161-year history and the worst result for any incumbent governing party in [[Ontario]]. The [[Green Party of Ontario]] won a seat for the first time in their history, while the [[Trillium Party of Ontario]] lost its single seat gained by a [[Crossing the floor|floor-crossing]] during the [[41st Parliament of Ontario|41st Parliament]].

==Background==
===Redistribution of seats===
The ''Electoral Boundaries Act, 2015''<ref>{{Cite canlaw|short title  =Electoral Boundaries Act, 2015|abbr =S.O.|year =2015|chapter =31|link= https://www.ontario.ca/laws/statute/s15031}}</ref> increased the number of electoral districts from 107 to 122, following the boundaries set out by the federal [[Canadian federal electoral redistribution, 2012|2013 Representation Order]] for Ontario, while preserving the special boundaries of the 11 seats in [[Northern Ontario]] set out in the 1996 redistribution.

The Far North Electoral Boundaries Commission, appointed in 2016,<ref>as a result of the {{Cite canlaw|short title  =Election Statute Law Amendment Act, 2016|abbr =S.O.|year =2016|chapter =33|section =36|link= https://www.ontario.ca/laws/statute/s16033}}</ref> recommended the creation of the additional districts of [[Kiiwetinoong]] and [[Mushkegowuk—James Bay]], carved out from the existing [[Kenora—Rainy River (provincial electoral district)|Kenora—Rainy River]] and [[Timmins—James Bay (provincial electoral district)|Timmins—James Bay]] ridings, which accordingly raised the total number of seats to 124.<ref>{{cite web|url= https://www.attorneygeneral.jus.gov.on.ca/english/about/pubs/fnebc/|title= Report: Far North Electoral Boundaries Commission|author= <!--Not stated-->|date= August 8, 2017|access-date= May 1, 2018|archive-date= March 19, 2018|archive-url= https://web.archive.org/web/20180319204331/https://www.attorneygeneral.jus.gov.on.ca/english/about/pubs/fnebc/|url-status= live}}</ref><ref>{{cite news|last1=Benzie|first1=Robert|title=Ontario to get 17 new ridings, including a constituency that is largely Indigenous|url=https://www.thestar.com/news/queenspark/2017/08/08/ontario-to-get-17-new-ridings-including-a-constituency-that-is-largely-indigenous.html|access-date=December 10, 2017|work=[[Toronto Star]]|date=August 8, 2017|archive-date=December 6, 2017|archive-url=https://web.archive.org/web/20171206135922/https://www.thestar.com/news/queenspark/2017/08/08/ontario-to-get-17-new-ridings-including-a-constituency-that-is-largely-indigenous.html|url-status=live}}</ref> This was implemented through the ''Representation Statute Law Amendment Act, 2017''.<ref>{{Cite canlaw|short title  =Representation Statute Law Amendment Act, 2017|abbr =S.O.|year =2017|chapter =18|link= https://www.ontario.ca/laws/statute/S17018}}</ref>

The new districts have been criticized as undemocratic, as they have a population of around 30,000 people compared with over 120,000 people in some southern Ontario constituencies. ''[[National Post]]'' columnist Josh Dehaas suggested that the small population sizes of the ridings might violate the [[Canadian Charter of Rights and Freedoms]].<ref>{{cite web|title=Ontario Liberals' plan for two new ridings could violate the Charter and cost PCs the election|url=https://nationalpost.com/opinion/josh-dehaas-ontario-liberals-plan-for-two-new-ridings-could-violate-the-charter-and-cost-pcs-the-election|work=[[National Post]]|access-date=January 13, 2017|date=August 3, 2017}}</ref>

In September 2017, a research firm analyzed the impact of redistribution if the boundaries had been in effect for the previous election.<ref>{{cite web|url= https://innovativeresearch.ca/wp-content/uploads/2017/07/OTM-1709-Counting-Seats-Not-Votes.pdf|title= Public Opinion Research: Ontario This Month|author= <!--Not stated-->|date= September 2017|website= innovativeresearch.ca|publisher= Innovative Research Group|pages= 17–23|access-date= May 20, 2018|archive-date= May 20, 2018|archive-url= https://web.archive.org/web/20180520193159/https://innovativeresearch.ca/wp-content/uploads/2017/07/OTM-1709-Counting-Seats-Not-Votes.pdf|url-status= live}}</ref>

===Change of fixed election date===
Under legislation passed in 2005, Ontario elections were to be held on "the first Thursday in October in the fourth calendar year following polling day in the most recent general election", subject to the [[Lieutenant-Governor of Ontario]]'s power to call an election earlier.<ref>{{Cite canlaw|short title  =Election Statute Law Amendment Act, 2005|abbr =S.O.|year =2005|chapter =35|section =1|subsection=3|link= https://www.ontario.ca/laws/statute/s05035}}</ref> As the current government had a [[Majority government|majority]], the passage of a [[non-confidence motion]] was not a likely option for calling an early election, though Premier [[Kathleen Wynne]] stated in June 2015 that she would likely advise to dissolve the Legislature in spring 2018 rather than in October of that year in order to avoid any conflict with municipal elections and take advantage of better weather and longer days.<ref>{{cite web|url=https://www.thestar.com/news/queenspark/2015/06/04/ontario-to-add-15-mpps-move-2018-election-date-ahead.html|title=Ontario to add 15 MPPs, move 2018 election date ahead|work=[[Toronto Star]]|last=Benzie|first=Robert|date=June 4, 2015|access-date=October 25, 2015|archive-date=November 1, 2015|archive-url=https://web.archive.org/web/20151101085543/http://www.thestar.com/news/queenspark/2015/06/04/ontario-to-add-15-mpps-move-2018-election-date-ahead.html|url-status=live}}</ref>

To put this on a statutory footing, in October 2016 [[Attorney General of Ontario]] [[Yasir Naqvi]] introduced a bill in the Legislative Assembly which, in part, included moving the election date to "the first Thursday in June in the fourth calendar year following polling day in the most recent general election",<ref name="torstar elxn set jun 2018"/> and it came into effect in December 2016.<ref>{{Cite canlaw|short title  =Election Statute Law Amendment Act, 2016|abbr =S.O.|year =2016|chapter =33|section =7|link= https://www.ontario.ca/laws/statute/s16033}}</ref>

===Prelude to campaign===
The [[Ontario Liberal Party]] attempted to win their fifth consecutive general election, dating back to [[2003 Ontario general election|2003]]. The [[Progressive Conservative Party of Ontario]] won their first election since [[1999 Ontario general election|1999]], and the [[Ontario New Democratic Party]] attempted to win their second election (having previously won in [[1990 Ontario general election|1990]]). Numerous other extra-parliamentary political parties also vied for votes.

The Liberals under [[Kathleen Wynne]] headed into the 2018 campaign trailing far behind the Progressive Conservatives, led by former [[Toronto City Council]]lor [[Doug Ford Jr.|Doug Ford]]. The Liberals' standing with voters had been badly hurt when they partially privatized Hydro One in 2015, after campaigning against it in the 2014 election, as well as rising criticism over "ballooning provincial debt, high electricity prices and costly, politically expedient decisions".<ref>{{Cite news|url=https://nationalpost.com/news/ontario-election-live-results-analysis-liberal-collapse-doug-ford-victory-how-it-happened|title=How a historic Liberal collapse and PC upheaval turned Ontario election into a wild horse race|date=June 7, 2018|work=[[National Post]]|access-date=June 12, 2018|first=Tom|last=Blackwell}}</ref><ref>{{Cite news|url=https://www.thestar.com/opinion/star-columnists/2018/05/30/the-day-kathleen-wynne-lost-the-2018-election.html|title=The day Kathleen Wynne lost the 2018 election|work=[[Toronto Star]]|access-date=June 12, 2018|date=May 30, 2018|first=Bob|last=Hepburn|archive-date=June 12, 2018|archive-url=https://web.archive.org/web/20180612232821/https://www.thestar.com/opinion/star-columnists/2018/05/30/the-day-kathleen-wynne-lost-the-2018-election.html|url-status=live}}</ref> In early April, the CBC published their analysis of aggregate polls showing that Ford and the Progressive Conservatives were ahead of the other parties averaging 42.1% support, compared to 27.2% for the governing Liberals, 23.4% for the NDP and 5.7% for the Greens<ref>{{cite news|last1=Grenier|first1=Eric|title=With nine weeks to go, the Ontario election is Doug Ford's to lose|url=http://www.cbc.ca/news/politics/grenier-ontario-poll-tracker-1.4603291|access-date=April 7, 2018|work=[[CBC News]]|date=April 6, 2018|archive-date=April 7, 2018|archive-url=https://web.archive.org/web/20180407015133/http://www.cbc.ca/news/politics/grenier-ontario-poll-tracker-1.4603291|url-status=live}}</ref> and with 11 Liberal MPPs announcing they would not be running for re-election or having already resigned their seats in the months leading up to the election.<ref>{{cite news|last1=Crawley|first1=Mike|title=11 Liberals won't run in Ontario election, and that's a problem for Kathleen Wynne|url=http://www.cbc.ca/news/canada/toronto/ontario-election-liberal-incumbents-not-running-1.4606871|access-date=April 7, 2018|work=[[CBC News]]|date=April 7, 2018|archive-date=April 9, 2018|archive-url=https://web.archive.org/web/20180409184047/http://www.cbc.ca/news/canada/toronto/ontario-election-liberal-incumbents-not-running-1.4606871|url-status=live}}</ref>

According to Wynne, voters were offered a "stark choice", between "cutting and removing supports from people" with "billions in cuts", which she alleged the Progressive Conservatives would do if they won the election, and expanding investments in social programs such as [[prescription drug]]s and [[childcare]], which the Liberal platform promised.<ref>{{cite news|title=Ontario voters facing 'stark choice' in June, says Kathleen Wynne|url=https://www.thestar.com/news/queenspark/2018/03/12/ontario-voters-facing-stark-choice-in-june-says-kathleen-wynne.html|access-date=April 7, 2018|work=[[Toronto Star]]|date=March 12, 2018|first=Kristin|last=Rushowy|archive-date=April 8, 2018|archive-url=https://web.archive.org/web/20180408073735/https://www.thestar.com/news/queenspark/2018/03/12/ontario-voters-facing-stark-choice-in-june-says-kathleen-wynne.html|url-status=live}}</ref>

In March 2018, the Liberals tabled a pre-election budget in the provincial legislature which promised billions of dollars in new spending for free childcare and expanded coverage for [[Dentistry|dental care]] but replaced the government's previous [[Government budget balance|balanced budget]] with a $6.7&nbsp;billion [[Deficit spending|deficit]] projected to last until 2024–2025.<ref>{{cite news|title=Ontario budget 2018: Liberals run deficit, introduce new spending in pre-election budget|url=https://globalnews.ca/news/4111673/ontario-budget-spending-liberals-election/|access-date=April 7, 2018|work=[[Global News]]|agency=[[Canadian Press]]|date=March 28, 2018|first1=Shawn|last1=Jeffords|first2=Paola|last2=Loriggio|archive-date=April 8, 2018|archive-url=https://web.archive.org/web/20180408074530/https://globalnews.ca/news/4111673/ontario-budget-spending-liberals-election/|url-status=live}}</ref> PC leader Doug Ford called the budget a "spending spree".<ref name="watt">{{cite news|title=Veering left is right for Kathleen Wynne|url=https://www.thestar.com/opinion/star-columnists/2018/04/01/jaime-watt-veering-left-is-right-for-wynne.html|access-date=April 7, 2018|work=[[Toronto Star]]|date=April 1, 2018|first=Jaime|last=Watt|archive-date=April 5, 2018|archive-url=https://web.archive.org/web/20180405185049/https://www.thestar.com/opinion/star-columnists/2018/04/01/jaime-watt-veering-left-is-right-for-wynne.html|url-status=live}}</ref>

===Mood of the voters===

* PCs had the lowest proportion of respondents (51%) not willing to vote for them at all, while the Liberals had the highest such proportion (64%)
* At 13%, the Liberals' "hard support" was only half that for the PCs
* For PCs, the strength of "hard support" increases with age, and older demographics tend to be more reliable voters
* Conversely, such support for the Liberals and NDP significantly declines with age, with almost ¾ of those aged 55+ not willing to vote for them at all
