Toronto Architecture: A Guide to the City’s Styles and Landmark Buildings
Toronto Architecture: A Guide to the City’s Styles and Landmark Buildings
Toronto architecture spans six clear eras: Victorian and Romanesque civic landmarks, Beaux-Arts railway grandeur, Art Deco towers, postwar Modernism, a Brutalist concrete wave, and 21st-century starchitect icons. This guide walks them in order, naming the buildings, their architects, and why each one still matters.
What defines Victorian and Romanesque Toronto?
Victorian Toronto built for permanence and civic pride. Three survivors anchor the era: a refined 1850 Italianate hall, a muscular 1899 Romanesque city hall, and a 1914 Gothic Revival castle. Together they show a young city dressing itself in the heavy, ornamented styles that signalled confidence across the late 1800s.
St. Lawrence Hall sits at 157 King Street East. Architect William Thomas completed it in 1850 in an Italianate, Renaissance Revival manner. It served as the city’s main concert and meeting hall, the social heart of Victorian Toronto.
Old City Hall, at 60 Queen Street West, is the era’s masterpiece. E.J. Lennox finished it in 1899 in the Richardsonian Romanesque style. It was the largest civic building in North America at completion, and its 103.6-metre clock tower still reads as a downtown landmark. It is a National Historic Site, and Lennox famously carved his own “signature” into the eaves.
Casa Loma, at 1 Austin Terrace, is Lennox again, this time in full Gothic Revival. Completed in 1914 for financier Sir Henry Pellatt, the castle remains the city’s most theatrical piece of residential architecture.
Why does this matter? These buildings set the template for civic seriousness. When Lennox built Old City Hall, he proved Toronto could match the scale and craft of any city on the continent.
How did Edwardian and Beaux-Arts shape the railway era?
The Edwardian decades gave Toronto its grandest public rooms, built around the railway. Two buildings define the moment, both completed within two years of each other and both tied to the firm Ross and Macdonald. They brought formal Beaux-Arts and Château styling to the foot of the city, where trains and travellers arrived.
Union Station, at 65 Front Street West, opened in 1927. It was designed by Ross and Macdonald with Hugh Jones and John M. Lyle, in the Beaux-Arts style. It is one of Canada’s finest railway stations, and its coffered Great Hall remains a genuine civic monument that thousands pass through daily.
Across the street, the Fairmont Royal York rose at 100 Front Street West in 1929. Ross and Macdonald designed it with Sproatt and Rolph in the Château style. At completion, it was the tallest building in the British Empire, a hotel scaled to the ambition of the rail age.
The pairing is deliberate. Station and hotel face each other as a single composition, a Beaux-Arts gateway that told arriving passengers exactly how serious Toronto had become.
What is Toronto’s Art Deco legacy?
Toronto’s Art Deco moment was brief but sharp, arriving with the early 1930s vogue for verticality and ornament. The clearest survivor in this guide is a single Bay Street bank tower that pairs height with a lavishly decorated interior, a small but confident statement of the style before the Depression slowed construction.
The Canada Permanent Trust Building, known simply as “The Permanent,” stands at 320 Bay Street. Sproatt and Rolph, led by Henry Sproatt, completed it in 1930. The 18-storey tower is restrained Art Deco outside, but it opens into an ornate, gilded banking hall that ranks among the most decorated interiors of the period in the city.
It matters because it shows the style at full polish. Art Deco never blanketed Toronto the way it did some American cities, so a single well-preserved example carries real weight.
How did Modernism remake the city?
Postwar Modernism stripped the ornament away and let structure speak. Two projects define the shift: a black steel-and-glass office complex that became Canada’s leading Miesian work, and a curved civic landmark born from a 1958 competition that drew more than 500 international entries. Both still set the tone for downtown.
The Toronto-Dominion Centre, at 66 Wellington Street West, was built in phases between 1967 and 1969. Mies van der Rohe designed it with John B. Parkin and Bregman and Hamann, in the International Style. It is Canada’s leading Miesian work, all black steel and glass, and it rewrote what a Toronto office tower could be.
Toronto City Hall and Nathan Phillips Square, at 100 Queen Street West, opened in 1965. Finnish architect Viljo Revell won the 1958 international competition against more than 500 entries. His design sets two curved towers around the council chamber, often described as an “eye.” Revell died in 1964, before the building he won was finished.
Why does this pairing matter? The TD Centre and City Hall arrived within a few years of each other and pulled Toronto fully into the modern world, one through corporate restraint and the other through civic optimism.
Why does Brutalism matter in Toronto?
The 1960s and 70s left Toronto its densest architectural layer: a Brutalist concrete wave across university and civic sites. Raw concrete megastructures like Robarts Library (1973) and the Andrews Building at U of T Scarborough (1964 to 1966) still divide opinion, decade after decade. The style is rich enough to warrant its own guide.
Robarts, at 130 St. George Street, was designed by Warner Burns Toan and Lunde with Mathers and Haldenby. Its triangular footprint earned it the nickname “Fort Book,” and it remains Toronto’s most famous Brutalist building. The Andrews Building, by John Andrews with Page and Steele, steps down the Highland Creek ravine and even landed on the cover of TIME in January 1967.
There is far more to the concrete story, from Raymond Moriyama’s Ontario Science Centre to the Toronto Reference Library. For the full tour, including the buildings, the architects, and the long debate over preservation, read our deeper guide to Brutalist architecture in Toronto.
Who are the contemporary names shaping Toronto?
The 21st century brought global architects to Toronto, several with personal ties to the city. Five buildings stand out, from Daniel Libeskind’s crystalline 2007 museum addition to Toronto-born Frank Gehry’s 2008 reworking of the gallery he grew up near. This is the era of the named “starchitect” and the twisting condo tower.
The Royal Ontario Museum’s Michael Lee-Chin Crystal, at 100 Queen’s Park, opened in 2007. Daniel Libeskind designed it with B+H in a deconstructivist style, five crystalline volumes crashing into the heritage museum. It is named for the benefactor who gave $30 million toward the project.
Transformation AGO, the Art Gallery of Ontario at 317 Dundas Street West, reopened in 2008. Frank Gehry, born in Toronto, designed it with Adamson, his first building in his home city. The 137-metre Galleria Italia, in glass and Douglas fir, runs along the front, with a blue-titanium wing to the south.
OCAD University’s Sharp Centre for Design, at 100 McCaul Street, came earlier, in 2004. Will Alsop, with Robbie/Young + Wright, lifted a pixelated black-and-white box roughly 26 metres into the air on multicoloured stilts. Torontonians call it the “tabletop.”
Further out, the Aga Khan Museum at 77 Wynford Drive in Don Mills opened in 2014. Fumihiko Maki designed the white-granite building with Moriyama and Teshima. It was North America’s first museum dedicated to Islamic art. Downtown, One Bloor East, by David Pontarini of Hariri Pontarini around 2016, brought 75 to 76 storeys of curved balconies and became an emblem of the 2010s condo boom.
One caveat on attribution. The CN Tower, at 290 Bremner Boulevard, opened in 1976 and stood as the world’s tallest free-standing structure until 2007 at 553.3 metres. It was an engineering-led project, designed by a team that included John Andrews, rather than the work of a single signature architect.
A GTA footnote belongs here too. The Absolute World “Marilyn Monroe” Towers, by MAD Architects with Burka in 2012, twist 56 and 50 storeys into the sky. They sit in Mississauga, not Toronto, but they remain the region’s most photographed contemporary residential design.
Where can you see Toronto design today?
The clearest place to see Toronto design in motion is the Interior Design Show (IDS Toronto), Canada’s largest design fair. The 2026 edition runs Thursday, January 22 to Sunday, January 25, 2026, at the Metro Toronto Convention Centre, North Hall, 255 Front Street West. Expect installations, product debuts, keynote talks, and a Professional Trade Day.
IDS has run since its first edition in January 1999, which drew roughly 25,000 visitors and speakers including Tyler Brûlé and Gijs Bakker. The fair has welcomed more than 660,000 cumulative visitors since, with 2025 marking its 26th edition. It is the single best snapshot of where local interiors and product design are heading.
Beyond the show, the city itself is the gallery. Walk Bay Street for Art Deco, the financial core for Mies, and the University of Toronto for concrete. And if a building sends you home wanting to reset your own space, here is our guide to where to shop for furniture in the city.
Look down as well as up. The same design thinking that shapes towers also shapes benches, ledges, and shelters, sometimes to discourage people from using them. Our piece on hostile architecture in Toronto covers that quieter, more contested layer of the streetscape.
Frequently asked questions
What architectural styles is Toronto known for?
Toronto is known for a layered mix rather than one signature style. The core eras are Victorian and Romanesque civic buildings, Beaux-Arts railway architecture, a small Art Deco moment, postwar International Style Modernism, a strong Brutalist concrete wave in the 1960s and 70s, and contemporary starchitect landmarks.
What is Toronto’s most famous building?
The CN Tower is Toronto’s most recognized structure. It opened in 1976 at 290 Bremner Boulevard and stood as the world’s tallest free-standing structure until 2007, at 553.3 metres. It was an engineering-led project designed by a team that included John Andrews, rather than the work of one architect.
Who designed Toronto City Hall?
Finnish architect Viljo Revell designed Toronto’s New City Hall, at 100 Queen Street West. He won a 1958 international competition that drew more than 500 entries, and the building opened in 1965. Revell died in 1964, before completion. Its two curved towers cradle the council chamber, often described as an “eye.”
What is the oldest building in this guide?
St. Lawrence Hall, at 157 King Street East, is the oldest landmark here. Architect William Thomas completed it in 1850 in an Italianate, Renaissance Revival style. It served as Victorian Toronto’s main concert and meeting hall, the social centre of the city in its day, and it still stands in the St. Lawrence neighbourhood.
Where can you see modern architecture in Toronto?
Start downtown. The Toronto-Dominion Centre at 66 Wellington Street West shows Mies van der Rohe’s International Style, and City Hall at 100 Queen Street West shows civic Modernism. For contemporary work, see the ROM Crystal, the AGO, and the Sharp Centre for Design at OCAD University.
