Etymology

The term "Greater Toronto" was first used in writing as early as the 1900s, although at the time, the term only referred to the old city of Toronto and its immediate townships and villages, which became Metropolitan Toronto in 1954 and became the current city of Toronto in 1998. Solomon, Lawrence "Toronto sprawls: a history." University of Toronto Press; 1 edition, p3 The use of the term involving the four surrounding regional municipalities came into formal use in the mid-1980s, after 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) or the still-broader "

On July 29, American forces landed at Burlington Beach (present-day Burlington) in an attempt to dislodge British forces at the adjacent Burlington Heights. However, finding the British forces too well-entrenched for any assault to be successful, the American naval force withdrew and proceeded east towards York. The American landings at York on July 31 went unopposed, with most of the soldiers garrisoned at York directed to defend Burlington Heights. The third incursion occurred a year later, when an American naval squadron arrived outside of York's harbour on August 6, 1814. The squadron dispatched to enter the harbour in order to gauge the town's defences, where it briefly exchanged cannon fire with Fort York before withdrawing to rejoin the American squadron outside the harbour. American forces did not attempt a landing during this incursion, although remained outside York's harbour for three days before departing. In 1816,

Since 1901

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''. 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. In 1953, the portion of York County south of Steeles Avenue, a concession road which formed a common boundary between several townships across the width of the county, was severed from it and incorporated as the Municipality of Metropolitan Toronto. With the concession of Metro Toronto, the offices of York County were moved from Toronto to Newmarket. Originally, the membership in Metropolitan Toronto included the City of Toronto and five townships: East York,

; as well as seven villages and towns, which became amalgamated into their surrounding townships in 1967. The early Metro Toronto government debated over the annexation of surrounding townships of Markham, Pickering and Vaughan. Frederick Goldwin Gardiner, the first Metro Toronto Chairman, planned on the conversion of these townships into boroughs of the Metro Toronto government. In 1971, the remaining areas of York County was replaced by the Ontario government with the Regional Municipality of York. In 1974, Ontario and Durham Counties were reorganized to become the Regional Municipality of Durham; Pickering west of Rouge River was transferred to Scarborough at that time. Peel County became Peel Region in 1974 as well. In 1980, North York would be incorporated into a city, with York following suit in 1983 and Etobicoke and Scarborough in 1984, although still part of the Metropolitan Toronto municipal government. In 1992, the Ontario government passed legislation requiring Metropolitan Toronto to include the rest of the Greater Toronto Area into its planning. Despite this however, there was fear different parts of the municipal system were working against one another. Because of this,

During this time, the Metro Toronto government advocated to the task force the creation of a new GTA authority, which would be made up of 21 of the 30 existing municipalities in the GTA at the time. The proposal from Metro Toronto would have resulted in 15 new municipalities. The City of Mississauga argued consolidation should only take place in such a way the new municipalities would have a population between 400,000 and 800,000. The Town of Markham had similarly advocated municipal consolidation in York Region, although it was opposed to complete consolidation into a single municipality. Municipal consolidation faced stiff opposition however from smaller communities such as Ajax, Milton, and the borough of East York. The task force's recommendation to eliminate the Metro Toronto government, and consolidate its remaining municipalities into an enlarged City of Toronto was completed in 1997 and became official in 1998, under the Common Sense Revolution of the then premier, Mike Harris. However, the task force's recommendation to create a GTA-tier municipality was not taken up by the Harris government, fearing a GTA-wide municipality would recreate the inter-municipal competitiveness that was believed to have impaired the former Metro Toronto government. Metrolinx, an agency of the Government of Ontario, was established to oversee public transit development across the Greater Toronto Area. The Greater Toronto Area hosted the 2015 Pan American Games.

Climate

The climate of the Greater Toronto Area is classified as humid continental, according to the

Much of the Greater Toronto Area is under Köppen ''Dfb'' ( warm summer subtype) zone, while Old Toronto (excluding the Toronto Islands) and some areas between there and Burlington to the south-west, are under the Köppen ''Dfa'' climate zone, the hot summer subtype. Precipitation averages annually, fairly distributed through the year but driest in later winter with higher average totals in the later summer. In winter, typical high temperatures will range from and low temperatures from . Cold arctic outbreaks keep daytime highs below for several days but this does not occur in every winter, while low temperatures sometimes drop below , accompanying wind chill makes this feel much colder. Annual snowfall averages between across the area. Mild and snow-free spells are also a feature of Toronto's winter, with temperatures surpassing for several days, to occasionally above . Spring is short and often cool to mild, snow can sometimes fall well into April, rarely accumulating. The transition from spring into summer can be rapid. Summer is warm on average to hot and moderately humid with high temperatures usually between , while low temperatures average between in the suburbs and downtown and near the lake. Although fairly sunny, summers do feature occasional heavy, thundery showers. Heat wave conditions with temperatures between are not uncommon but very rarely does the temperature exceed . Immediate lakeshore locations have generally lower average maximum temperatures but they can also experience hot conditions when offshore winds prevail. Normally in autumn it alternates between wet and dry with lengthy periods of mild and calm weather. Temperatures fall and windspeeds increase sharply in November and by December, cold and snowy weather are more common as the temperature average falls below .

Most of the GTA's farmland is in Durham Region, with 55% of their total land area being farmland. This is followed by York Region with 41% of their lands being farmland, Peel Region with 34%, and Halton Region with 41%. Toronto's remaining farmland is completely within Rouge Park in the Rouge Valley. The average size of the farm in the GTA () is much lower than the farms in the rest of Ontario (averaging ). This has been attributed to the shift of farm types in the GTA from the traditional livestock and cash crop farms (requiring an extensive land base), towards more intensive enterprises including greenhouse, floriculture, nursery, vegetable, fruit, sheep and goats. The most numerous farm types in the GTA are miscellaneous specialty farms (including horse and pony, sheep and lamb, and other livestock specialty), followed by cattle, grain and oilseed, dairy and field crop farms. Although the output of dairy production has dropped with farms from within the GTA, dairy has remained the most productive sector in the agricultural industry by annual gross farm receipts. Despite the decreased amount of farmland around the region, farm capital value increased from $5.2 billion in 1996 to $6.1 billion in 2001, making the average farm capital value in the GTA continued to be the highest in the province.

also handles international flights handles some discount flights and charters and acts as an alternative to Pearson. The Billy Bishop Toronto City Airport on the Toronto Islands near downtown is used for civil aviation, air ambulance traffic and regional scheduled airlines (it handled nearly two million passengers in 2012). There are also a number of smaller airports scattered throughout the GTA. The International Air Transport Association (IATA) uses ''YTO'' as a code for multiple airports in the area, including those without passenger service. The Greater Toronto Airport Authority has also placed a tentative proposal to develop a new airport in Pickering (which also extends over into Markham and Uxbridge). As the GTAA predicts Toronto Pearson would be unable to be the sole provider for the bulk of Toronto's commercial air traffic in the next 20 years from the report's publication in 2004 (i.e. in 2024), they believe a new airport in Pickering would address the need for a regional/reliever airport east of Toronto Pearson, as well as complement the airport in Hamilton, Ontario.Pickering Airport Draft Plan Report

Communication

The Greater Toronto Area is served by seven distinct telephone area codes. Before 1993, the GTA used the 416 area code. In a 1993 zone split, Metropolitan Toronto retained the 416 code, while the other municipalities of the Greater Toronto Area were assigned the new
area code 905 Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while ''surface area'' refers to the area of an open s ...
. This division by area code has become part of the local culture to the point where local media refer to something inside Toronto as "the 416" and outside of Toronto as "the 905". For example, the Raptors 905 basketball team in the

), is the only community in the GTA that uses the 519 area code, which covers most of Southwestern Ontario. To meet the increased demand for phone numbers, two overlay area codes were introduced in 2001. Area code 647 (supplementing the 416 area code) was introduced in March 2001 and area code 289 (supplementing the 905 area code) was introduced in July 2001. Some individuals within the 905 area code region may have to dial long distance to reach each other; although residents of Mississauga and Hamilton share the same area code (905), an individual from Toronto, for example, would have to dial " 1" to reach Hamilton, but not to reach Mississauga. Ten-digit telephone dialling, including the area code for local calls, is required throughout the GTA. In March 2013, two additional area codes were introduced to the GTA: area code 437 in Toronto and area code 365 in the area served by 905 and 289.

Federal politics

Federally, the Conservative Party of Canada, Conservatives, Liberal Party of Canada, Liberals, and the New Democratic Party, New Democrats (NDP) all hold several electoral district (Canada), electoral districts in the GTA. The City of Toronto has often been supportive of the Liberal Party. Traditionally, Liberal support is strongest in Downtown Toronto, while Conservative support is stronger in the surrounding communities outside Toronto. The NDP also has a strong base within the GTA. The Greater Toronto Area has the ability to influence election results and determine the governing party in Canada, due in part to its large population and riding count. 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. 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. Toronto's political leanings now appeared to mirror those of surrounding communities that leaned toward the Conservatives. 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. 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. The 2019 Canadian federal election, 2019 and 2021 Canadian federal election, 2021 federal elections have similar results.


Provincial politics

Toronto is the capital of Ontario with the Ontario Legislative Building, often Metonymy, metonymically known as Queen's Park (Toronto), Queen's Park after the street and park surrounding it, being located in downtown Toronto. Most of the provincial government offices are also located in downtown Toronto. On the provincial level of government, the Progressive Conservative Party of Ontario, Ontario Progressive Conservatives, Ontario Liberal Party, Ontario Liberals, and the Ontario New Democratic Party, Ontario New Democrats all hold electoral districts in the GTA. 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. 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 a number of 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, they have seen some successes in Brampton and Durham Region, where they hold one seat each. The Progressive Conservative Party of Ontario has not won a riding in the city of Toronto during a general election since 1999. On the other end of the spectrum, the NDP saw major losses in Toronto during the 2014 election, and only hold two seats in the city. This 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 and this continues to hold true in the 2022 Ontario general election, 2022 provincial election.


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. Unusual for a large North American urban agglomeration, the GTA has very few agencies with powers that can cross boundaries. Attempts to create an interregional organization have been made, such as the Province of Ontario's Office of the Greater Toronto Area (OGTA) in 1988 and the Greater Toronto Services Board (GTSB) in 1998,e/?search=browseRepealed&context= Greater Toronto Services Board Act, 1998

, the population of this area is 6,712,341. Population growth studies have projected the City of Toronto's population in 2031 to be 3,000,000 and the Greater Toronto Area's population to be 7,450,000, while the Ministry of Finance (Ontario), Ontario Ministry of Finance states it could reach 7.7 million by 2025. Statistics Canada identified in 2001 that four major urban regions in Canada exhibited a cluster pattern of concentrated population growth among which included the Golden Horseshoe, Greater Golden Horseshoe Census Region, which includes all of the Greater Toronto Area (which includes Oshawa), as well as other Southern Ontario cities including Niagara, Hamilton, Guelph, Kitchener-Cambridge-Waterloo and Barrie. Combined, the Greater Golden Horseshoe has a population of 9,765,188 in 2021, containing over 20% of Canada's population. The Toronto CMA also has the largest proportions of foreign-born residents (46%) 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 over the composition of its ethnicities. The four largest foreign-born populations of Toronto only constitute 15% of the total foreign-born population. This is opposed to the four largest foreign-born populations of other metropolitan areas such as New York and London, where they make up 25% of their respective foreign-born populations. Statistics Canada also found in 2006, there were 31,910 Indigenous people living in the Greater Toronto Area, which represented 2.7% of all Indigenous peoples in Canada and 13.2% of those in Ontario. The majority of which, however, are not registered with the Indian reserves within the Greater Toronto Area, the Chippewas of Georgina Island First Nation and the Mississaugas of Scugog Island First Nation.
