Southwestern Ontario is a secondary region of Southern Ontario in the Canadian province of Ontario. It occupies most of the Ontario Peninsula bounded by Lake Huron, including Georgian Bay, to the north and northwest; the St. Clair River, Lake St. Clair, and Detroit River, to the west; and Lake Erie to the south. To the east, on land, Southwestern Ontario is bounded by Central Ontario and the Golden Horseshoe. The region had a population of 2,796,367 in 2021.


Southwestern Ontario is often not consistently defined. The Government of Ontario, in certain documents, classifies municipalities along the eastern side of Southwestern Ontario near the Grand River, including Wellington County, Waterloo Region, and Brant County, as part of the Greater Golden Horseshoe region that surrounds western Lake Ontario, mainly due to the presence of modern transportation connections that link these areas to the core sections of the Golden Horseshoe.[1] A more traditional definition of the region boundary can be traced back to early colonial districts in the British Province of Quebec and Upper Canada. The Western District, originally known as the Hesse District from 1788 to 1792,[2] was originally designated as everything west of a north-south line intersecting the extreme projection of Long Point into Lake Erie,[3] which roughly follows the eastern boundaries of modern Grey, Dufferin, Wellington, Brant, and Norfolk Counties.

The northern portion of Southwestern Ontario is sometimes referred to as Midwestern Ontario. This area includes Perth, Huron, Wellington, Dufferin, Bruce, and Grey Counties, corresponding roughly with the historical boundaries of Queen's Bush, an area of crown land that did not see formal subdivision or wide-scale settlement until the 1830s.

Archaeological findings from the Princess Point Complex suggest that indigenous peoples grew maize in the region as early as 260 CE. Iroquoians are recognizable from 500 CE, and by 900 CE longhouse villages began appearing near modern-day Brantford.[4]

Europeans settlement began in the early 18th century, when it was part of the Royal Province of New France. One of the oldest continuous settlements in the region is Windsor, which originated as a southerly extension of the settlement of Fort Detroit in 1701. With the transfer of New France to British control in 1763, the region was part of the British Province of Quebec, 1774 to 1791; the Province of Upper Canada, 1791 to 1841; and the Canada West division of the Province of United Canada, 1841 to Confederation in 1867, when United Canada was formally partitioned into the provinces of Ontario and Quebec.

During the 19th century and early 20th century, the largest city in Southwestern Ontario was Windsor; however, as both cities grew, Windsor was outpaced by the faster growth of London, and passed the mantle of regional anchor to that city in the 1960s. Late in the 20th century the Kitchener–Cambridge–Waterloo metropolitan area became the most populous metropolitan area in southwestern Ontario surpassing the London-St. Thomas metropolitan area, and serves as the anchor of Midwestern Ontario.

Southwestern Ontario is a prosperous agricultural region whose chief crops are tobacco, sweet corn, soybean, winter wheat, canola, and tomatoes.[5] Additionally, Southwestern Ontario has developed a significant concentration of commercial greenhouses, predominantly centred in the town of Leamington, where tomatoes, peppers, cucumbers, flowers, and cannabis are grown. It is the largest concentration of commercial greenhouses in North America. Dairy and beef farming, breeding and training of standardbred horses and wine growing and production are also important industries. Its climate is among the mildest in Canada. Although brief periods of winter can be severe, summers are hot and humid with a longer growing season than in most of the country.

A large section of Southwestern Ontario was part of the Talbot Settlement, and the region has benefited from the settlement’s facilitation of agriculture and of trade in general. Its economy is heavily tied in with that of the midwestern United States, in particular the border state of Michigan. Auto manufacturing and parts, agriculture and hi-tech industries are key components of the region’s economy. The region also provides important transportation routes for commercial trucking, railway and tanker shipping from Detroit-Windsor and Port Huron, Michigan-Sarnia linking Canada with major markets in the eastern and midwestern United States.

Bruce Peninsula National Park near Tobermory, Ontario

Southwestern Ontario is located within the Mixedwood Plains Ecozone (as classified by Environment and Climate Change Canada, further subclassified into the Lake Erie Lowland and Manitoulin-Lake Simcoe regions),[9] which largely consists of glacial till plains underlain by sedimentary limestone bedrock. The vast majority of Southwestern Ontario maintains a relatively flat geography with rolling hills, with the exception of areas near the Niagara Escarpment in Bruce and Grey Counties, where exposed limestone cliff faces can be seen along the shores of Georgian Bay. Sandier soils are generally located near Lake Erie, resulting in the creation of a sandy escarpment along the entire north shore, in addition to many sandspit peninsulas, including Point Pelee in Essex County, Pointe aux Pins (Rondeau) in Chatham-Kent, and Long Point in Norfolk County. Pelee Island, the southernmost populated area in Canada, is located south of Point Pelee in Lake Erie.

Southwestern Ontario was originally covered by vast forests prior to agricultural development in the region. Two forest regions are located in Southwestern Ontario;[10] Carolinian forest, located predominantly along Lake Erie and the southern tip of Lake Huron,[11] and Great Lakes-St. Lawrence forest, located around Lake Huron and Georgian Bay.[12] A very small percentage of forest coverage areas remain in the region due to extensive agricultural development and urbanization, but conservation efforts are underway to preserve and/or protect these forests. Three major federally protected areas, Point Pelee National Park, Bruce Peninsula National Park, and Long Point National Wildlife Area, are located in Southwestern Ontario. In 2021, the federal government announced plans to designate a new National Urban Park in Windsor's Ojibway Prairie Complex.[13]

The Carolinian forest zone is Canada's smallest forest zone, but it is home to a very high biodiversity of species due to it being one of the warmest regions in the country. Over 500 rare and/or endangered species are located in this region[11] and is estimated to contain around 25% of Canada's species at risk, including the American badger, Midland painted turtle, Jefferson salamander, monarch butterfly, and southern flying squirrel.[14]


Köppen Climate Map of Southwestern Ontario

Southwestern Ontario's climate is heavily influenced by the proximity of the Great Lakes. Winters in the region are typically milder than the rest of Ontario due to the gradual release of stored heat in the lakes. Despite this, however, portions of the region experience significantly more snow than others due to lake-effect snow caused by eastward winds. A portion of the regional Snowbelt is located in Bruce, Grey, Huron, and Middlesex Counties.[15] In a sharp contrast, Essex County and Chatham-Kent receive less snow than average due to their location further south.[16] Summers are typically hot and humid, with Windsor experiencing the warmest weather in Ontario. Summers are often cooler and less humid on the peninsulas in Lake Erie and Lake Huron. Southwestern Ontario also experiences the highest annual frequency of thunderstorms in Canada, with Windsor, Chatham-Kent, and London experiencing the most days on average with lightning per year.[17] Southwestern Ontario also regularly experiences severe weather events, including tornadoes, due to its proximity to the Great Lakes and warmer-than-average weather during the summer.

Under the Köppen climate classification, the vast majority of Southwestern Ontario has a humid continental climate, with the vast majority of the area experiencing a warm-summer Dfb climate, with the exception of Windsor and Chatham-Kent, which experiences a hot-summer Dfa climate. Additionally, a very small area near Long Point experiences a temperate oceanic Cfb climate, due to its location in Lake Erie creating slightly cooler summers and slightly warmer winters than the remainder of the province.



Southwestern Ontario has historically been a strong centre for Canadian agricultural production, given the abundance of arable land and warmer climate that provides for a longer growing season than the rest of the country. The vast majority of land in the region is used for agriculture. Common crops grown in the region include sweet corn, soybean, winter wheat, and canola. Tobacco was also historically grown in the tobacco belt, centred on the towns of Delhi, Aylmer, and Tillsonburg in Elgin, Oxford, and Norfolk Counties from the 1920s until the early 2000s, when Ontario bought out the tobacco quotas of most farms in the region in 2008 for $300,000,000 CAD.[18] While some tobacco farms still remain, most have switched to alternative crops, including specialty crops like ginseng, hazelnut, and mushrooms. Fruits such as blueberries, strawberries, raspberries, blackberries, gourds, apples, and tomatoes are also grown in the region. Cattle ranching is also another important agricultural industry in Southwestern Ontario, with dairy and beef farming, standardbred horse breeding and training, sheep, poultry, and pig farming being common. The dairy and cheesemaking industry in Southwestern Ontario has been predominantly concentrated in Oxford, Perth, and Wellington Counties, with the region accounting for approximately 56% of Ontario's milk production as of 2020.[19] Sugar bushes for maple syrup production also have a modest presence in the region.[20]

A strong commercial greenhouse sector has also emerged in the region, centred predominantly on the towns of Leamington and Kingsville in Essex County, which boast the largest concentration of commercial greenhouses in North America,[21] made viable due to the presence of sandy soils, low energy costs, and mild winters. Crops such as tomatoes, cucumbers, bell peppers, berries, flowers, and cannabis are grown year-round in these greenhouses, providing a domestic source of out-of-season crops throughout Canada in the winter.

The region is also a centre for wine production. While the vast majority of wine production in Ontario is currently located in the Niagara Region and Prince Edward County, a wine appellation designated by the Vinters Quality Alliance (VQA), the regulatory system for wine in Ontario and British Columbia, is located on the Lake Erie north shore and Pelee Island in Essex County. Additionally, the VQA recognizes additional emerging wine regions located in Norfolk County, Georgian Bay, and Lake Huron east shore.[22]


The energy sector is a major industry in Southwestern Ontario. Energy production in the region is sourced from a mixture of nuclear, hydroelectric, wind, solar, and natural gas sources. The vast majority of energy in the region is produced by the Bruce Nuclear Generating Station in Kincardine. The plant is the second largest nuclear generating station in the world. The plant began operation in 1971 and currently has a generating capacity of 6,550 MW spread across 8 CANDU PHWR reactors. It is anticipated to eventually reach a generating capacity of 7,000 MW through uprates achieved as a result of an ongoing reactor refurbishment program.[23] In 2023, the Ontario government announced plans to expand the plant's generating capacity by an additional 4,800 MW to meet growing energy demands in the province.[24] Additional energy production is supplemented by wind, solar, and hydroelectric power. Large-scale wind turbine fields are located predominantly in Essex County, Chatham-Kent, and Lambton County. Belwood Lake, Conestogo Lake, Fanshawe Lake, Guelph Lake, Pittock Reservoir, and Wildwood Lake are all artificial reservoirs created for local hydroelectric production.

The petrochemical and oil/natural gas industry also has a long history in the region. Oil was initially discovered in Canada in 1858, when the first oil well was advanced in Oil Springs, located in Lambton County.[25] However, oil and petrochemicals did not play a significant role in the regional economy until the large-scale development of oil deposits in Alberta in the 1930s and after World War II, when the first large-scale oil refineries were built in Sarnia. Oil was originally shipped by tankers through the Great Lakes from Superior, Wisconsin until the 1953 expansion of the Enbridge pipeline system into Sarnia. Today, Sarnia is home to 3 major oil refineries owned by Suncor, Imperial Oil, and Shell Canada. An additional refinery owned by Imperial Oil is located in Nanticoke.[26] These refineries collectively supply much of the province's fuel demand, in addition to providing feedstocks for the chemical industry. Additionally, smaller-scale oil and natural gas development is common in rural Ontario, with small shale oil pools and natural gas deposits being found in local sedimentary bedrock.[27] Shale oil pools are commonly found in Essex County, Chatham-Kent, and Lambton County, where small oil wells can often be seen operating on farms. Natural gas deposits are largely found and exploited along the Lake Erie north shore and under the Lake Erie lake bed.[28]

The chemical industry also has a strong presence in Sarnia, to the point that the area including Sarnia and St. Clair Township is colloquially known as Chemical Valley. The chemical industry has its origins around the same time as the oil industry, during World War II, when tropical sources of natural latex for rubber production were being threatened. The federal government designated Sarnia as the area where synthetic petroleum-based rubbers would be developed for use in the allied war effort.[29] Over time, various chemical companies, including Bayer and NOVA Chemicals, have built many facilities in the region for the production of various chemicals, including plastics, paints, lubricants, food additives, cosmetics, rubbers, and other chemicals. The presence of local underground salt beds resulted in a readily-available supply of brine and chlorine, which has aided the ease of production of chemicals locally.[30]



Ambassador Bridge in Windsor, Ontario

The vast majority of the primary vehicular traffic network in Southwestern Ontario is served mainly by the controlled-access 400-series highways. Highway 401, the main highway in the network, starts in Windsor at the terminus of the under-construction Gordie Howe International Bridge and runs northeast to Waterloo Region, where it continues northeast through the Golden Horseshoe and Eastern Ontario. Highway 402, another major highway, runs east from the United States border with Michigan in Sarnia to London, where it connects with Highway 401 in southern London. Highway 403 connects with Highway 401 in Woodstock and runs east toward Brantford, where it continues toward Hamilton and the Greater Toronto Area. Additional major provincial highways in the region include Highway 3, Highway 4, Highway 6, Highway 7, Highway 8, Highway 10, and Highway 85.

Additionally, the cities of Windsor and London have municipally-owned expressways. E.C. Row Expressway is a fully grade-separated freeway running east-west through Windsor, formerly known as Highway 2. Veteran's Memorial Parkway is a limited-access highway running north-south through London, formerly known as Highway 100. Dougall Avenue is a road in Windsor with a small section of freeway running north from Highway 401, formerly known as Highway 3B. Highbury Avenue is a road that runs from St. Thomas to London, with a small section of freeway running north from Highway 401, formerly known as Highway 126.

Southwestern Ontario also has multiple road connections with the United States. These include the Ambassador Bridge in Windsor, the Bluewater Bridge in Sarnia, and the Detroit-Windsor Tunnel that runs from downtown Detroit to downtown Windsor. A new bridge crossing, the Gordie Howe International Bridge, is currently under construction and slated to open in 2025,[31] and is meant to serve as a direct freeway-to-freeway connection between Highway 401 and E.C. Row in Windsor and Interstate 75 in Detroit.


Via Rail operates inter-regional passenger train service on the Quebec City–Windsor Corridor, in Windsor-London-Toronto and Sarnia-London-Toronto configurations, running both on the northern route through Stratford and Kitchener, and the southern route through Woodstock and Brantford.[32] GO Transit also operates inter-regional commuter rail in the region, currently limited to as far west as Waterloo Region on the Kitchener Line.[33] In fall 2021, the provincial government announced a pilot program extending GO commuter rail service to London through Stratford and St. Mary's, but this service was discontinued in fall of 2023 due to poor ridership and travel times along the corridor.[34] As of 2024, the provincial government and Waterloo Region are planning for an extension of GO rail service into Cambridge.[35] Only one municipality in Southwestern Ontario, Waterloo Region, currently has a rail-based transit system in operation. This transit system is known as the iON LRT and runs from Waterloo to Kitchener.[36] A southern extension of this rail line into Cambridge is currently being planned.[37]

Freight rail in the region is dominated by CN Rail and CPKC, the two major cross-national Canadian rail companies. Smaller railway companies operating in the region include Essex Terminal Railway, Goderich-Exeter Railway, Ontario Southland Railway, Southern Ontario Railway, and Waterloo Central Railway.[38]


Southwestern Ontario has two major ports, located in Goderich and Windsor, that service cargo ships as part of the Great Lakes/St. Lawrence Seaway system. The Port of Goderich is predominantly used for the export of salt from the Goderich Salt Mine, but also moves grain and calcium chloride.[39] The Port of Windsor is significantly more developed and is the third-busiest Great Lakes port, behind the ports in Hamilton and Thunder Bay. The port of Windsor moves a wider variety of cargo including aggregates, salt, grain, fertilizer, lumber, steel, petroleum, vehicles and machinery.[40] Minor ports are also located in Sarnia, Kingsville, Owen Sound, and Nanticoke.

The Owen Sound Transportation Company currently operates passenger ferry services connecting Leamington to Pelee Island, and Tobermory to Manitoulin Island in Northern Ontario.[41]


Southwestern Ontario is home to three major airports; Region of Waterloo International Airport (YKF), London International Airport (YXU), and Windsor International Airport (YQG), in addition to multiple minor airports in various smaller communities, such as Sarnia Chris Hadfield Airport (YZR) and St. Thomas Municipal Airport (YQS). The three major airports predominantly offer limited international flights (mainly to vacation destinations such as the United States, Mexico, and the Caribbean) on a seasonal basis, in addition to some select all-season routes to other Canadian cities. All airports also offer frequent connecting flights to Toronto Pearson International Airport (YYZ), usually via Air Canada.[42][43][44]



The accent/dialect in the region, Southwestern Ontario English, is distinct from the rest of Ontario.[45]

Southwestern Ontario has never been the home of any professional sports franchises from the contemporary "Big Six" leagues (MLB, NBA, NFL, NHL, MLS, and CFL), with the exception of the NHL's Detroit Cougars (now the Detroit Red Wings) in 1926-1927, when they played at the Border Cities Arena (now Windsor Arena) in Windsor for a singular season while the Detroit Olympia was under construction. Multiple cities historically hosted professional hockey teams from the OPHL in the early 20th century who competed for the Stanley Cup prior to the formation of the NHL in 1917, including the Berlin Dutchmen (who challenged the Montreal Wanderers for the Cup in 1910), Brantford Indians, Galt Professionals (who challenged the Ottawa Senators for the Cup in 1909 and 1911), Guelph Royals, and Waterloo Colts. The region has also historically hosted multiple Canadian football teams that competed for the Grey Cup prior to the formation of the CFL in 1958, including the Brantford Redskins, Kitchener-Waterloo Dutchmen, London Lords, Sarnia Imperials (2-time Grey Cup champions in 1934 and 1936), and Windsor Royals of the Ontario Rugby Football Union.

The London-Kitchener TV market, as of 2023, is the fourth largest sports media market in Canada, and the largest in Canada without representation from a "Big Six" professional team.[46] Various additional professional teams currently and have formerly existed in lower-tier professional leagues in the region, with the only current active professional teams being basketball teams in the Basketball Super League, and semi-professional baseball and soccer teams in the Intercounty Baseball League and League1 Ontario, respectively. Major junior hockey is a major fixture of the sporting landscape in the region, with all major cities hosting OHL teams. Southwestern Ontario teams regularly experience high attendance, with the London Knights and Kitchener Rangers regularly boasting the highest attendance in the league.[47]
