Sainte-Dorothée is a district in Laval, Quebec. It was a separate city until the municipal mergers on August 6, 1965.
The Sainte-Dorothée that was known for forest and farmlands is no longer what it used to be. It took a giant transformation during the last decade with the arrival of SmartCentre (formerly Mega Center) Sainte-Dorothée and Mega Centre Notre-Dame. It began with the construction of Canadian Tire, IGA & followed with the first Wal-Mart Canada in the western Laval area. The expansion has never stopped since. It now has almost every major department store, restaurant, hundreds of boutiques and two locations open 24 hours. The area also saw a rise in demand for residential development, possibly due to the "Mega Mall" alongside the Highway 13 or the other way around as the mall was built to accommodate the growing number of families looking for affordable homes near the Montreal area. Given the proximity of Ste-Dorothée to Pierrefonds, Saint-Laurent, the rest of Montreal and major highways, it was only a matter of time that it would be developed.
