About Us

Our story

Alexis Nihon was born in Liege, Belgium, in 1902, and immigrated to Canada at the age of 18. After World War II, he acquired several parcels of land on the Island of Montreal and rented them out to developers. One prime location, at the corner of Ste-Catherine Street and Atwater Avenue, was developed into a major complex by two companies, first Atwater-Western and then Montrad.

The architects, Harold Ship and Stanley King, originally envisaged Alexis Nihon as a multi-purpose complex combining a shopping center, office towers, residential housing and a medical center. The Alexis Nihon was built in 1967, and three years later, the first office tower and the Plaza Tower residences were added. The Nihon family bought the Complex in 1983, and completed the project by adding a second office tower in 1986. However, they decided against building the medical centre as originally planned.

Since then, Alexis Nihon has consolidated its assets, and today is home to over 100 stores, some 40 tenants in its office towers, and the residents of the Plaza Tower’s 426 apartments.
