List of tallest buildings in Mississauga

Mississauga is a city in Southern Ontario in Canada, and the second most populous city in the Greater Toronto Area (GTA) after Toronto itself, with 717,961 inhabitants as of 2021.^[1] Since the 2000s, there have been an increasing number of skyscrapers and high-rise built in Mississauga, almost all of which is residential. As of 2025, Misissauga is home to 41 buildings taller than 100 m (328 ft), six of which have a height greater than 150 m (492 ft). The tallest building in the city is M2, a 200 m (656 ft), 62-story building completed in 2023. Alongside Vaughan, Mississauga has one of the largest collections of tall buildings in the GTA outside of Toronto.

Developed as a suburb of Toronto, Mississauga's growth is attributed to its proximity to that city.^[2] However, Mississauga's extensive corporate and industrial employment opportunities differentiate it from suburban bedroom communities. The first high-rises in the city appeared in the early 1970s, which each subsequent decade resulting in increased building heights. Between 2000 and 2010, Mississauga's skyline grew from having one high-rise taller than 100 m (328 ft) to 19.

In 2006, developers Fernbrook & Citizen held an international architectural design competition for a high-rise condoninium complex.^[3][4] The winning submission by MAD Architects was realized as Absolute World. Featuring two twisting, sinuous skyscrapers, the complex was completed in 2012. They remained the tallest buildings in Mississauga until 2023, upon the completion of M2 and its slightly shorter companion, M1. M2 and M1 are part of M City Condominiums, an eight-tower, 15-acre, 4.3 million square foot mixed-use community. The tallest building in the development, M3, is currently under construction. At a planned height of 260 m (854 ft), it will become the tallest building in Mississauga and in all of Canada outside of Toronto upon its expected completion in 2026.^[5]

Mississauga's tallest buildings are concentrated in Mississauga City Centre, forming a ring of high-rises that surround Square One Shopping Centre, the second largest shopping centre in Canada.^[6] A number of towers sit alongside Hurontario Street, which runs northwest-southeast through the city. The lakeside neighbourhood of Port Credit also has a small grouping of high-rises, none of which exceed 100 m (328 ft) in height.
