DDO, as residents call it, is one of the most populous cities on the West Island. Its diverse housing stock — bungalows, cottages, townhouses — reflects three decades of intensive suburban development between 1970 and 2000.
Dollard-des-Ormeaux offers a complete range of housing types. Older areas to the south feature 1970s bungalows, while northern and eastern neighbourhoods contain more recent 1990s construction. This diversity demands an in-depth knowledge of each construction era and its characteristic materials.
DDO sits on glacial deposits of clay and till. Some areas developed in the 1970s-80s used backfill containing pyrite beneath basement slabs. This mineral swells on contact with moisture and oxygen, heaving floors and cracking foundations — a costly problem that still affects some DDO properties.
