to 2010. In 2012, The St. Regis Toronto (then known as Trump International Hotel and Tower) was completed, with a top dome height of 252 m (827 ft) and an antenna height of 277 metres (908 ft), making it the fourth-tallest structure in Toronto and all of Canada. With the completion in late 2014 of Aura—which, at 78 storeys and a height of 272 m (892 ft), is the tallest residential building in Canada—the tallest building under construction is the 309-metre (1,014 ft) tall The One (though the developer applied for a height increase to ), also a residential building. Natalie Alcoba of the National Post described this phenomenon as the "Manhattanization" of Toronto in reference to the built-up nature of the namesake island borough in New York City. In one week of 2018, Toronto City Council approved 755 storeys of new development in the city's downtown core. The Toronto skyline (especially the CN Tower) can be spotted by the naked eye during clear daylight skies from locations as far as Newmarket from the north, Clarington from the east, several points along the Niagara Escarpment from the west, and Fort Niagara State Park in the south across Lake Ontario in the U.S. state of New York. As of January 2023, Toronto has constructed 81 skyscrapers and has a further 36 under construction. Toronto also has 92 skyscrapers that are either approved or in the proposal stage. Toronto currently ranks 20th in the world with most skyscrapers already completed, third in North America and first in Canada. Toronto ranks fourth in the world and first in North America with the number of skyscrapers under construction. Ranking by standard height There are 80 skyscrapers in Toronto that stand at least ranked by standard height measurement as of October 2021. This includes spires and architectural details, but does not include antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings. An asterisk (*) indicates that a building has been topped out, but not completed. The "Year" column indicates the year in which a building was completed. Freestanding observation and/or telecommunication towers, while not habitable buildings, are included for comparison purposes; however, they are not ranked. One such tower is the CN Tower. Ranking by pinnacle height Skyscrapers and other structures may also be measured based on their pinnacle height, which includes radio masts and antennas.
