The projects include residential, shopping and office developments in the historic centre of the Mexican capital, and an upmarket development called Santa Fe on the outskirts.
Manuel Camacho Solis, mayor of the city, said the projects were part of a plan to renovate the centre, which has buildings dating back to the 16th century.
Paul Reichmann said the projects would revitalise areas devastated by the earthquake in 1985, while Mexico's economic reforms would create demand for office space.
'High-quality business environments must be built to meet the demands of an increasingly sophisticated and international business community,' Mr Reichmann said.
The Reichmanns' Olympia and York Developments filed for bankruptcy last year because of debt on its Canadian properties. The Mexico City projects will be their first attempt at international development since the failure of the Canary Wharf project in London in 1992.
