Toronto covers an area of , An Outer Harbour was constructed southeast of downtown during the 1950s and 1960s, and it is now used for recreation. Toronto's limits are formed by Lake Ontario to the south, the western boundary of
Marie Curtis Park,
Etobicoke Creek,
Eglinton Avenue, and
Highway 427 to the west,
Steeles Avenue to the north, and the
Rouge River and the Scarborough–Pickering Townline to the east.
Topography crossing the
Don valley ravine in 2023. The
Toronto ravine system and its
waterways cut through the city's landscape. The city is mostly flat or gentle hills, and the land gently slopes upward away from the lake. The flat land is interrupted by the
Toronto ravine system, which is cut by numerous creeks and rivers of the
Toronto waterway system, most notably the Humber River in the west end, the
Don River east of downtown (these two rivers flanking and defining the Toronto Harbour), and the Rouge River at the city's eastern limits. Most of the ravines and valley lands in Toronto today are parklands and recreational trails are laid out along the ravines and valleys. The original town was laid out in a
grid plan on the flat plain north of the harbour, and this plan was extended outwards as the city grew. The width and depth of several of the ravines and valleys are such that several grid streets, such as
Finch Avenue,
Leslie Street,
Lawrence Avenue, and
St. Clair Avenue, terminate on one side of a ravine or valley and continue on the other side. Toronto has many bridges spanning the ravines. Large bridges such as the
Prince Edward Viaduct were built to span broad river valleys. Despite its deep ravines, Toronto is not remarkably hilly, but its elevation does increase steadily away from the lake. Elevation differences range from
above sea level at the Lake Ontario shore to above sea level near the
York University grounds in the city's north end at the intersection of
Keele Street and Steeles Avenue. There are occasional hilly areas; in particular,
midtown Toronto, as well as the
Silverthorn and
Fairbank neighbourhoods, have several sharply sloping hills. Lake Ontario remains occasionally visible from the peaks of these ridges as far north as Eglinton Avenue, inland. The other major geographical feature of Toronto is its escarpments. During the
last ice age, the lower part of Toronto was beneath
Glacial Lake Iroquois. Today, a series of
escarpments mark the lake's former boundary, known as the "Iroquois Shoreline". The escarpments are most prominent from
Victoria Park Avenue to the mouth of
Highland Creek, where they form the
Scarborough Bluffs. Other observable sections include the area near St. Clair Avenue West between
Bathurst Street and the Don River, and north of
Davenport Road from Caledonia to
Spadina Road; the
Casa Loma grounds sit above this escarpment. The geography of the lakeshore has dramatically changed since the first settlement of Toronto. Much of the land on the harbour's north shore is landfill, filled in during the late 19th century. Until then, the lakefront docks (then known as wharves) were set back farther inland than today. Much of the adjacent Port Lands on the harbour's east side was a
wetland filled in early in the 20th century. The shoreline from the harbour west to the Humber River has been extended into the lake. Further west, landfill has been used to create extensions of land such as Humber Bay Park. , an island chain that bounds
Toronto's Inner Harbour The Toronto Islands were a natural peninsula until a storm in 1858 severed their connection to the mainland, creating a channel to the harbour. The peninsula was formed by
longshore drift taking the sediments deposited along the Scarborough Bluffs shore and transporting them to the Islands area. The other source of sediment for the Port Lands wetland and the peninsula was the deposition of the Don River, which carved a wide valley through the sedimentary land of Toronto and deposited it in the shallow harbour. The harbour and the channel of the Don River have been dredged numerous times for shipping. The lower section of the Don River was straightened and channelled in the 19th century. The former mouth drained into a wetland; today, the Don River drains into the harbour through a concrete waterway, the
Keating Channel. To mitigate flooding in the area, as well as to create parkland, a second more natural mouth was built to the south during the first half of the 2020s, thereby creating a new island,
Ookwemin Minising.
Neighbourhoods and former municipalities , which form the current City of Toronto. Toronto encompasses an area formerly administered by several separate municipalities that were amalgamated over the years. Each developed a distinct history and identity over the years, and their names remain in common use among Torontonians. Former municipalities include East York, Etobicoke,
Forest Hill,
Mimico, North York,
Parkdale, Scarborough,
Swansea,
Weston and York. Throughout the city, there exist hundreds of small neighbourhoods and some larger neighbourhoods covering a few square kilometres. The many residential communities of Toronto express a character distinct from the skyscrapers in the commercial core.
Victorian and
Edwardian-era residential buildings can be found in enclaves such as
Rosedale,
Cabbagetown,
The Annex, and
Yorkville. The
Wychwood Park neighbourhood, historically significant for the architecture of its homes, and for being one of Toronto's earliest planned communities, was designated as an Ontario Heritage Conservation district in 1985. The
Casa Loma neighbourhood is named after "
Casa Loma", a castle built in 1911 by
Sir Henry Pellat, complete with gardens, turrets, stables, an elevator, secret passages, and a bowling alley.
Spadina House is a 19th-century
manor that is now a museum.
Old Toronto -era
Bay-and-gable houses are a distinct architectural
style of residence that is ubiquitous throughout the older neighbourhoods of Toronto. The pre-amalgamation City of Toronto covers the downtown core and older neighbourhoods to the east, west, and north. It is the most densely populated part of the city. The Financial District contains the
First Canadian Place,
Toronto-Dominion Centre,
Scotia Plaza,
Royal Bank Plaza,
Commerce Court and
Brookfield Place. This area includes, among others, the neighbourhoods of
St. James Town,
Garden District,
St. Lawrence,
Corktown, and
Church and Wellesley. From that point, the Toronto skyline extends northward along Yonge Street. Old Toronto is also home to many historically wealthy residential enclaves, such as
Yorkville, Rosedale, The Annex, Forest Hill,
Lawrence Park,
Lytton Park,
Deer Park,
Moore Park, and Casa Loma, most stretching away from downtown to the north. East and west of downtown, neighbourhoods such as
Kensington Market,
Chinatown,
Leslieville,
Cabbagetown and
Riverdale are home to bustling commercial and cultural areas as well as communities of artists with studio lofts, with many middle- and upper-class professionals. Other neighbourhoods in the central city retain an ethnic identity, including two smaller Chinatowns, the
Greektown area,
Little Italy,
Portugal Village, and
Little India, among others.
Suburbs and the surrounding area from the air. Crescent Town was a post-World War II suburban neighbourhood developed in
East York. The inner suburbs are contained within the former municipalities of York and East York. These are mature and traditionally working-class areas, consisting primarily of post–World War I small, single-family homes and small apartment blocks. Sections were long established and quickly growing towns before the suburban housing boom began and the emergence of metropolitan government, existing towns or villages such as Mimico,
Islington and
New Toronto in Etobicoke;
Willowdale,
Newtonbrook and
Downsview in North York;
Agincourt,
Wexford and
West Hill in Scarborough where suburban development boomed around or between these and other towns beginning in the late 1940s. Upscale neighbourhoods were built, such as the
Bridle Path in North York, the area surrounding the Scarborough Bluffs in
Guildwood, and most of central Etobicoke, such as
Humber Valley Village, and
The Kingsway. One of the largest and earliest "planned communities" was
Don Mills, parts of which were first built in the 1950s. Phased development, mixing single-detached housing with higher-density apartment blocks, became more popular as a suburban model of development. During the late 20th century,
North York City Centre and
Scarborough City Centre developed separate downtown districts outside Downtown Toronto after the former boroughs were promoted to cities. High-rise development in these areas has given these former municipalities distinguishable skylines of their own, with high-density transit corridors serving them; some of these
developments are also transit-oriented.
Industrial holds the most extensive collection of preserved Victorian industrial architecture in North America. In the 1800s, a thriving industrial area developed around Toronto Harbour and the lower Don River mouth, linked by rail and water to Canada and the United States. Examples included the Gooderham and Worts Distillery, Canadian Malting Company, the Toronto Rolling Mills, the Union Stockyards and the
Davies pork processing facility (the inspiration for the "Hogtown" nickname). This industrial area expanded west along the harbour and rail lines and was supplemented by the infilling of the marshlands on the east side of the harbour to create the Port Lands. A garment industry developed along lower Spadina Avenue, the "
Fashion District". Beginning in the late 19th century, industrial areas were set up on the outskirts, such as
West Toronto / The Junction, where the Stockyards relocated in 1903. The Great Fire of 1904 destroyed a large amount of industry in the downtown. Some companies moved west along King Street, and some moved as far west as Dufferin Street, where the large
Massey-Harris farm equipment manufacturing complex was located. Over time, pockets of industrial land mostly followed rail lines and later highway corridors as the city grew outwards. This trend continues to this day; the largest factories and distribution warehouses are in the suburban environs of
Peel and
York Regions, but also within the current city: Etobicoke (concentrated around
Pearson Airport), North York, and Scarborough. is a
former industrial site in downtown Toronto that has undergone redevelopment. Many of Toronto's
former industrial sites close to (or in) downtown have been redeveloped, including parts of the Toronto waterfront, the rail yards west of downtown, and
Liberty Village, the Massey-Harris district and large-scale development is underway in the
West Don Lands. The Gooderham & Worts Distillery produced spirits until 1990 and is preserved today as the "Distillery District", the largest and best-preserved collection of
Victorian industrial architecture in North America. Some industry remains in the area, including the
Redpath Sugar Refinery. Similar areas that retain their industrial character but are now largely residential are the Fashion District, Corktown, and parts of South Riverdale and Leslieville. Toronto still has some active older industrial areas, such as
Brockton Village, Mimico and New Toronto. In the west end of Old Toronto and York, the Weston/
Mount Dennis and The Junction areas still contain factories, meat-packing facilities and rail yards close to medium-density residential. However, the Junction's Union Stockyards moved out of Toronto in 1994. Formerly a marsh that was filled in to create industrial space, it was never intensely developed—its land unsuitable for large-scale development—because of flooding and unstable soil. It still contains numerous industrial uses, such as the
Portlands Energy Centre power plant, port facilities, movie and television production studios, concrete processing facilities, and low-density industrial facilities. The
Waterfront Toronto agency has developed plans for a naturalized mouth to the Don River and to create a flood barrier around the Don, making more of the land on the harbour suitable for higher-value residential and commercial development. A former chemicals plant site along the Don River is slated to become a large commercial complex and transportation hub.
Architecture 's main building Toronto's buildings vary in design and age, with many structures dating back to the early 19th century, while other prominent buildings were just newly built in the first decade of the 21st century. Lawrence Richards, a member of the Faculty of Architecture at the
University of Toronto, has said, "Toronto is a new, brash, rag-tag place—a big mix of periods and styles."
Bay-and-gable houses, mainly found in Old Toronto, are a distinct architectural feature of the city. Toronto is a city with a substantial amount of skyscrapers and high-rise buildings. The city has
106 skyscrapers taller than , the
16th-most in the world and the most in Canada by far. There are currently three "
supertall" skyscrapers (taller than ) under construction in the city, and more have been approved. Defining the Toronto skyline is the
CN Tower, a telecommunications and tourism hub. Completed in 1976 at a height of , it was the world's tallest freestanding structure until 2007 when it was surpassed by
Burj Khalifa in
Dubai. Through the 1960s and 1970s, significant pieces of Toronto's architectural heritage were demolished to make way for redevelopment or parking. In contrast, since 2000, amid the
Canadian property bubble, Toronto has experienced a condo construction boom and architectural revival, with several buildings opened by world-renowned architects.
Daniel Libeskind's
Royal Ontario Museum addition,
Frank Gehry's remake of the
Art Gallery of Ontario, and
Will Alsop's distinctive
OCAD University expansion are among the city's new showpieces. The mid-1800s Distillery District, on the eastern edge of downtown, has been redeveloped into a pedestrian-oriented arts, culture and entertainment neighbourhood. This construction boom has some observers call the phenomenon the
Manhattanization of Toronto after
the densely built island borough of New York City.
Climate The city of Toronto has a hot summer
humid continental climate (
Köppen:
Dfa), though was on the threshold of a warm summer humid continental climate (
Dfb) until the 20th century due to the
urban heat island but still found in the
metropolitan region, with warm, humid summers and cold winters. According to the classification applied by
Natural Resources Canada, the city of Toronto is in plant hardiness zone 7a. Some suburbs and nearby towns have lower zone ratings. The city experiences four distinct seasons, with considerable variance in length. As a result of the rapid passage of weather systems (such as high- and low-pressure systems), the weather is variable from day to day in all seasons. However, it can be noticeably cooler on many spring and early summer afternoons under the influence of a lake breeze, since Lake Ontario is cool relative to the air during these seasons. During the winter months, temperatures are usually below . The highest temperature ever recorded in Toronto was on July 8, 9 and 10, 1936, during the
1936 North American heat wave. The coldest temperature ever recorded was on January 10, 1859. and forms the entrance to
City Hall.
Sankofa Square, near City Hall, has also gained attention in recent years as one of the busiest gathering spots in the city. Other squares include
Maple Leaf Square, next to
Scotiabank Arena, and the civic squares at the former city halls of the defunct Metropolitan Toronto, most notably
Mel Lastman Square in North York. There are many large downtown parks, which include
Allan Gardens,
Christie Pits,
Grange Park,
Little Norway Park,
Moss Park,
Queen's Park,
Riverdale Park and
Trinity Bellwoods Park. An almost-hidden park is the compact
Cloud Gardens, which has both open areas and a glassed-in greenhouse, near Queen Street and Yonge Street. South of downtown are two large parks on the waterfront: Tommy Thompson Park on the
Leslie Street Spit, which has a nature preserve and is open on weekends, and the
Toronto Islands, accessible from downtown by ferry. , a botanical garden operated by
Toronto Parks and Recreation Division Large parks in the outer areas managed by the city include
High Park,
Humber Bay Park,
Centennial Park (Etobicoke),
Downsview Park,
Guild Park and Gardens,
Sunnybrook Park and
Morningside Park (Scarborough). Toronto also operates several public golf courses. Most ravine lands and river bank floodplains in Toronto are public parklands. After
Hurricane Hazel in 1954, construction of buildings on floodplains was outlawed, and private lands were bought for conservation. In 1999, Downsview Park, a former military base in North York, initiated an international design competition to realize its vision of creating Canada's first
urban park. Approximately , or 12.5 per cent of Toronto's land base, is maintained parkland. Morningside Park in Scarborough is the largest park managed by the city, which is in size. ==Demographics==
