==Etymology==
The term "Greater Toronto" was first used in writing as early as the 1900s although at the time, the term referred only to the [[Old Toronto|old city of Toronto]] and to its immediate townships and villages, which became [[Metropolitan Toronto]] in 1954 and became the current city of Toronto in 1998.<ref name=Toexp>[[Lawrence Solomon|Solomon, Lawrence]] "Toronto sprawls: a history." University of Toronto Press; 1 edition, {{ISBN|0-7727-8618-6}} p3</ref> The use of the term involving the four surrounding regional municipalities came into formal use in the mid-1980s, when it was used in a widely discussed report on municipal governance restructuring in the region and was later made official as a provincial planning area. However, it did not come into everyday usage until the mid-to-late 1990s.

In 2006, the term began to be supplanted in the field of spatial planning as provincial policy increasingly began to refer to either the "[[Greater Toronto and Hamilton Area]]" (GTHA){{efn|Adopters include the regional transportation planning body [[Metrolinx]],<ref name="Metrolinx About Us">{{cite web|url=http://www.metrolinx.com/en/aboutUs.aspx|title=About Us|work=Metrolinx Website|publisher=Metrolinx|access-date=February 26, 2010|archive-url=https://web.archive.org/web/20100505042359/http://www.metrolinx.com/en/aboutUs.aspx|archive-date=May 5, 2010|url-status=live}}</ref> the [[Ministry of Energy (Ontario)|Ministry of Energy and Infrastructure]]<ref name="Places to Grow" /> and the [[Regional Municipality of Halton]].<ref name="Halton ROPA 138" />}} or the still-broader "[[Golden Horseshoe|Greater Golden Horseshoe]]".<ref name="MIERE">{{cite web|url = http://www.mei.gov.on.ca/en/pdf/infrastructure/GrowthPlan_Brochure.pdf|title = Planning for Growth|work = Understanding the Growth Plan for the Greater Golden Horseshoe|publisher = Ministry of Public Infrastructure Renewal|url-status = dead|archive-url = https://web.archive.org/web/20110706192438/http://www.mei.gov.on.ca/en/pdf/infrastructure/GrowthPlan_Brochure.pdf|archive-date = July 6, 2011|df = mdy-all}}</ref> The latter includes the Greater Toronto Area's satellite municipalities, such as [[Peterborough, Ontario|Peterborough]], [[Barrie]], [[Guelph]], [[Kitchener, Ontario|Kitchener]], [[Waterloo, Ontario|Waterloo]], [[Cambridge, Ontario|Cambridge]] and [[Regional Municipality of Niagara|Niagara Region]]. The GTA continues, however, to be in official use elsewhere in the [[Government of Ontario]], such as the [[Ministry of Finance (Ontario)|Ministry of Finance]].

Some [[List of municipalities in the Greater Toronto Area|municipalities considered part of the GTA]] are not within the Toronto [[Census geographic units of Canada#Census metropolitan areas|Census Metropolitan Area]] (CMA), which is smaller than the land area and population of the GTA planning area. For example, [[Oshawa]] is the centre of its own CMA, yet deemed part of the Greater Toronto Area, while other municipalities, such as [[New Tecumseth]] in southern [[Simcoe County]] and [[Mono, Ontario|Mono Township]] in [[Dufferin County]] are included in the '''Toronto CMA''' but not in the GTA.<ref name=GTAvsCMA>{{cite web| url=https://www.toronto.ca/wp-content/uploads/2017/10/90c1-EDC-Map-GTA-CMA.png| title=Greater Toronto Area and Toronto CMA Map| publisher=[[Municipal government of Toronto|City of Toronto]]| access-date=February 7, 2018| archive-url=https://web.archive.org/web/20180209002816/https://www.toronto.ca/wp-content/uploads/2017/10/90c1-EDC-Map-GTA-CMA.png| archive-date=February 9, 2018| url-status=live}}</ref> These different border configurations result in the GTA's population being higher than the Toronto CMA by nearly one-half million people, often leading to confusion amongst people when trying to sort out Toronto's urban population.

Other nearby urban areas, such as [[Hamilton, Ontario|Hamilton]], [[Barrie]], [[Regional Municipality of Niagara|St. Catharines-Niagara]] or [[Regional Municipality of Waterloo|Kitchener-Waterloo]], are not part of the GTA or the Toronto CMA, but form their own CMAs near the GTA.<ref>{{cite web|title=Population of census metropolitan areas (2006 Census boundaries)|url=http://www40.statcan.ca/l01/cst01/demo05a-eng.htm|publisher=[[Statistics Canada]]|access-date=March 2, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100213110909/http://www40.statcan.ca/l01/cst01/demo05a-eng.htm|archive-date=February 13, 2010}}</ref> Ultimately, all the aforementioned places are part of the Greater [[Golden Horseshoe]] metropolitan region, an [[Urban area|urban agglomeration]],<ref>{{cite web|title=2006 Census: Portrait of the Canadian Population in 2006: Subprovincial population dynamics|url=http://www12.statcan.ca/census-recensement/2006/as-sa/97-550/p14-eng.cfm|publisher=[[Statistics Canada]]|access-date=March 2, 2010|archive-url=https://web.archive.org/web/20100408114007/http://www12.statcan.ca/census-recensement/2006/as-sa/97-550/p14-eng.cfm|archive-date=April 8, 2010|url-status=live}}</ref> which is the [[List of the largest urban agglomerations in North America|fifth most populous in North America]].

===Extended area===
The term "[[Greater Toronto and Hamilton Area]]" (GTHA) refers to the GTA, and the city of [[Hamilton, Ontario|Hamilton]], located along the western border of the Greater Toronto Area. The term has been adopted by several organizations, including [[Metrolinx]] and the [[Ministry of Energy (Ontario)|Ministry of Energy]])<ref name="Metrolinx About Us" /><ref name="Places to Grow"/> because of the growing commuter population in the combined region. The GTHA and the [[Regional Municipality of Niagara]] form the inner ring of the larger [[Golden Horseshoe|Greater Golden Horseshoe]], an urban agglomeration and secondary region of Ontario.

The idea towards a streamlined local government to control local infrastructure was made as early as 1907 by, [[William Findlay Maclean]], a member of parliament and founder of ''[[The Toronto World]]'', who called for the expansion of the government of the former City of Toronto in order to create a ''Greater Toronto''.<ref name=Toexp /> The idea for a single government municipality would not be seriously explored until the late 1940s when planners decided the city needed to incorporate its immediate suburbs. However, due to strong opposition from suburban politicians, a compromise was struck, which resulted in the creation of [[Metropolitan Toronto]].<ref>[[Lawrence Solomon|Solomon, Lawrence]] "Toronto sprawls: a history."

The proposal from Metro Toronto would have resulted in 15 new municipalities.

Vast parts of the region remain farmland and forests, making it one of the distinctive features of the geography of the GTA. Most of the urban areas in the GTA hold large urban forest. For the most part designated as parkland, the ravines are largely undeveloped.

===Climate===
The [[Geography of Toronto#Climate|climate of the Greater Toronto Area]] is classified as [[humid continental climate|humid continental]], according to the [[Köppen climate classification]]. Much of the Greater Toronto Area is under Köppen ''Dfb'' ([[Humid continental climate#Warm summer subtype|warm summer subtype]]) zone. [[Old Toronto]] (excluding the [[Toronto Islands]]) and some areas between there and [[Burlington, Ontario|Burlington]] to the southwest are under the Köppen ''Dfa'' climate zone, the [[Humid continental climate#Hot summer subtype|hot summer subtype]]; this is the result of the urban heat island effect, especially in Old Toronto. Precipitation averages {{convert|832|mm|abbr=on}} annually, which is fairly distributed through the year but is driest in later winter with higher average totals in the later summer.

In winter, typical high temperatures will range from {{convert|-5|to|3|C}} and low temperatures from {{convert|-12|to|-5|C}}. Cold arctic outbreaks keep daytime highs below {{convert|-10|C}} for several days but that does not occur in every winter, and low temperatures sometimes drop below {{convert|-18|C|F}}, with the accompanying [[wind chill]] making that feel much colder. Annual snowfall averages between {{convert|80|and|150|cm|abbr=on}} across the area. Mild and snow-free spells are also a feature of Toronto's winter, with temperatures surpassing {{convert|5|C}} for several days to occasionally above {{convert|15|C}}. Spring is short and often cool to mild, and snow can sometimes fall well into April but rarely accumulates. The transition from spring into summer can be rapid. Summer is warm on average to hot and moderately humid with high temperatures typically between {{convert|24|and|31|C}}, while low temperatures average between {{convert|15|C}} in the suburbs and {{convert|18|to|20|C}} downtown and near the lake. Although fairly sunny, summers have long stretches of humid conditions that give rise to frequent thunderstorm activity, and very heavy rainfall sometimes results in flash flooding. Heat wave conditions with temperatures between {{convert|32|and|35|C}} are common but typically do not last long, and rarely temperatures rarely reach {{convert|38|C}}. Humidex values can be high during heat episodes; at their highest, they have exceeded {{convert|50|C}}. Immediate lakeshore locations have generally lower average maximum temperatures but they can also experience hot conditions when offshore winds prevail. Normally, autumns alternate between wet and dry with lengthy periods of mild and calm weather. Temperatures fall and windspeeds increase sharply in November. By December, cold and snowy weather is more common, and the average temperature falls close to or just below {{convert|0|C}}.

From [[1993 Canadian federal election|1993]] to [[2011 Canadian federal election|2011]], a centre-right party failed to win a single seat in the former Metro Toronto.{{Citation needed|date=February 2025}} In the 2011 election, however, a surge in NDP support combined with a collapse in Liberal support allowed the Conservatives to win eight seats in Toronto itself, and another 24 in the suburbs.{{Citation needed|date=February 2025}} Toronto's political leanings now appeared to mirror those of surrounding communities that leaned toward the Conservatives.{{Citation needed|date=February 2025}}

The election of 2011 showed Liberal support, based on votes in the GTA, had collapsed from 43.7% to 30.6%, giving the Liberals only 14.9% of the local seats in the House of Commons. However, the support of the Conservatives and NDP increased accordingly, with the Conservatives increasing their vote share from 31.5% to 42.2% (and capturing 68.1% of the GTA seats) and the NDP increasing from 14.6% to 23.2% of the vote and 17% of the local Federal ridings.{{Citation needed|date=February 2025}}

In the [[2015 Canadian federal election|2015 federal election]], the Liberals regained their dominance of the GTA after suffering devastating losses there four years earlier. They defeated a number of prominent incumbents from both the NDP and the Conservatives. The Liberals took all of Toronto itself. They also took back almost all of the suburban ridings they had lost in 2011. Both the NDP and the Conservatives suffered heavily as their support collapsed in the inner city and the suburbs respectively. Only a few Conservatives held onto their seats in the outer ring of the GTA, while the NDP failed to elect any MPs in this area.<ref>{{cite web |work=Toronto Star |url=https://www.thestar.com/news/federal-election/2015/10/19/red-wave-rolls-over-the-gta.html |title=Red wave rolls over the GTA |last=Rider |first=David |date=October 19, 2015 |archive-url=https://web.archive.org/web/20180210002228/https://www.thestar.com/news/federal-election/2015/10/19/red-wave-rolls-over-the-gta.html |archive-date=February 10, 2018 |access-date=November 3, 2015}}</ref> The [[2019 Canadian federal election|2019]], [[2021 Canadian federal election|2021]] and [[2025 Canadian federal election|2025 federal elections]] have similar results.

On the provincial level of government, the [[Progressive Conservative Party of Ontario|Ontario Progressive Conservatives]] (PCs), [[Ontario Liberal Party|Ontario Liberals]], and the [[Ontario New Democratic Party|Ontario New Democrats]] all hold electoral districts in the GTA.<ref>{{cite news|title=Ontario Votes 2007 – Regional results|url=http://www.cbc.ca/ontariovotes2007/ridings/|publisher=CBC|location=Canada|access-date=March 24, 2010|archive-url=https://web.archive.org/web/20100525151136/http://www.cbc.ca/ontariovotes2007/ridings/|archive-date=May 25, 2010|url-status=live}}</ref> While the GTA provided a strong base of support for the Progressive Conservative government between 1995 and 2003, the Ontario Liberal Party achieved a major victory in the GTA during the [[2003 Ontario general election|2003 election]] and has enjoyed strong support from the region ever since.<ref>{{cite news |title=Liberals surge in Toronto, 905 ridings |url=https://www.cbc.ca/news/canada/liberals-surge-in-toronto-905-ridings-1.648626 |publisher=CBC |location=Canada |access-date=March 24, 2010 |date=October 11, 2007 |archive-url=https://web.archive.org/web/20100914010518/http://www.cbc.ca/canada/ontariovotes2007/story/2007/10/10/gta-ridings.html |archive-date=September 14, 2010 |url-status=live }}</ref> In the [[2011 Ontario general election|2011 election]], the Liberals won 33 of the 44 available seats in the GTA, allowing Premier [[Dalton McGuinty]] to hold onto a minority government. The [[2014 Ontario general election|2014 election]] under McGuinty's successor, [[Kathleen Wynne]], was an even bigger electoral landslide for the Liberals, as they won 38 seats in the region. They even took several ridings in territory that had voted PC for decades, like Durham, Burlington, Newmarket-Aurora and Halton. The PCs hold no seats in Peel Region and only one seat in each of the Halton, York, and Durham regions. While the NDP has been weak in the GTA since the [[1995 Ontario general election|1995 election]], it has seen some successes in Brampton and Durham Region, where they hold one seat each.

The Progressive Conservative Party of Ontario did not win a riding in the City of Toronto during a general election from 1999 to 2018.<ref>{{cite news|title=GTA Liberal ridings shut out vote-hungry Tories|url=https://www.cbc.ca/news/canada/gta-liberal-ridings-shut-out-vote-hungry-tories-1.1024439|publisher=CBC|location=Canada|access-date=October 7, 2011|date=October 7, 2011|archive-url=https://web.archive.org/web/20111007132836/http://www.cbc.ca/news/canada/ontariovotes2011/story/2011/10/06/gta-election-results.html|archive-date=October 7, 2011|url-status=live}}</ref> On the other end of the spectrum, the NDP saw major losses in Toronto during the 2014 election and held only two seats in the city. That is no longer the case since the [[2018 Ontario general election|2018 provincial election]], as the Progressive Conservatives and the NDP made significant gains at the expense of the Liberals; that continues to hold true in the [[2022 Ontario general election|2022]] and [[2025 Ontario general election|2025 provincial elections]].

===Municipal politics===
In 2011, 244 politicians govern the Greater Toronto Area below the provincial and federal levels, holding offices in cities, towns, and regional municipalities.<ref>Lorinc, John.

=== Immigration ===
In 2009, the Toronto CMA also has one of the largest proportions of foreign-born residents (46 per cent) as a share of the total population out of all metropolitan areas in the [[OECD|Organization for Economic Co-operation and Development (OECD)]]. The Toronto region is also unusually diverse in the composition of its ethnicities. The four largest foreign-born populations of Toronto constitute only 15 per cent of the total foreign-born population. That is opposed to the four largest foreign-born populations of other metropolitan areas such as New York City and London, where they make up 25 per cent of their respective foreign-born populations.<ref name="Reviews OECD Territorial Reviews p35"/>

==Education==
Education in the Greater Toronto Area is managed by the provincial [[Ministry of Education (Ontario)|Ministry of Education]], who manages preschool, elementary and secondary education, while the provincial [[Ministry of Colleges and Universities]] administers laws relating to [[tertiary education]], including [[college (Canada)|colleges]], universities, and [[vocational school]]s.<ref>{{cite web|url=http://www.edu.gov.on.ca/eng/about/|title=About the Ministry|work=Government of Ontario|author=Ministry of Education, Ontario|publisher=Queen's Printer for Ontario, 2010|year=2010|access-date=December 14, 2010|archive-url=https://web.archive.org/web/20101220050217/http://www.edu.gov.on.ca/eng/about/|archive-date=December 20, 2010|url-status=live}}</ref><ref>{{cite web|url=http://www.edu.gov.on.ca/eng/tcu/about/|title=Welcome to TCU|work=Government of Ontario|author1=Ministry of Training, Colleges|author2=Universities, Ontario|publisher=Queen's Printer for Ontario, 2010|year=2010|access-date=December 14, 2010|archive-url=https://web.archive.org/web/20101221023447/http://www.edu.gov.on.ca/eng/tcu/about/|archive-date=December 21, 2010|url-status=live}}</ref>

===Primary and secondary education===
There are presently twelve [[state school|public]] English [[first language]] [[Board of education|school board]]s, and two French first language school boards operating within the GTA. Seven of these school boards operate [[secular education|secular schools]], whereas the other seven operate [[separate school]]s; the seven separate school boards in the Greater Toronto Area all serve the [[Catholic Church|Roman Catholic faith]]. In addition to public schools, there are also many [[Independent school|private schools]] that operate within Greater Toronto.

Three of these GTA-based public school boards also manage institutions outside Greater Toronto, the two French first language school boards, based in Toronto, as well as the [[Dufferin-Peel Catholic District School Board]] (DPCDSB). Conversely, English first language public schools in [[Clarington]], a municipality within Durham Region, are managed by school boards based outside the GTA.
