This is a list of the tallest buildings in Montreal, ranking skyscrapers in the city of Montreal, Quebec, Canada, by height. There are currently 67 buildings and structures in Montreal greater than 100 m (328 ft). The tallest building by roof height in the city is the 51-storey, 205 m, 1000 de La Gauchetière. However, for international comparisons, spires are included as per the Council on Tall Buildings and Urban Habitat's most widely used height definition for building height and thus the tallest building according to this definition is the 1250 René-Lévesque at 226.5m (199m without its spire). Municipal regulations forbid any building from exceeding the smallest of the following two conditions: the height of Mount Royal, or 232,5 m (764 ft) above mean sea level or 200m of building height. Above-ground height is further limited in most areas and a minority of the downtown land plots are allowed to contain buildings exceeding 120 metres in height. The maximum limit of 232.5m above mean sea level or height of the Mont Royal is currently attained by 1000 de La Gauchetière (205m) and 1250 René-Lévesque (199m without its decorative spire), the latter of which is shorter, but built on higher ground. The 1000 de La Gauchetière was built before the 1992 municipal ruling on maximum building height. The history of skyscrapers in Montreal began with the completion of the eight-storey-tall New York Life Insurance Building in 1888. Most high-rise construction in Montreal occurred in three periods: the late 1920s to the early 1930s, the early 1960s to the early 1990s and the 2010s into the 2020s. In the 21st century, the rate of high-rise construction in the city increased again with more under construction in 2014 than in any other North American city bar Toronto and New York City.

Tallest buildings

This list ranks buildings in Montreal that stand at least 100 m (328 ft) tall, based on CTBUH height measurement standards. 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. 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 Tour de Montréal.
