Toronto's architecture is a testament to the city's rich history and its continued growth as a global metropolis. With buildings dating back to the early 19th century, Toronto combines historical structures with contemporary designs, creating a unique urban landscape. The city's architecture is marked by its diversity, blending several styles, including the iconic Bay-and-gable houses in Old Toronto, with modern high-rises that define the skyline.

One of Toronto's most famous landmarks is the CN Tower, once the tallest freestanding structure in the world until 2007. It remains a focal point of the city, alongside newer architectural wonders such as Daniel Libeskind's Royal Ontario Museum addition, Frank Gehry's Art Gallery of Ontario redesign, and the striking OCAD University extension by Will Alsop. This architectural boom has led to the city's skyline being described as the "Manhattanization of Toronto" by some critics, pointing to the rapid growth in condominium construction that has reshaped the cityscape since the 2000s.

In addition to these modern developments, the historic Distillery District has been transformed into a cultural hub, showcasing Toronto's ability to preserve its heritage while embracing the future. As the city continues to expand, the juxtaposition of old and new architecture will undoubtedly remain a defining feature of Toronto's urban identity.
