In many neighbourhoods, such as Villeray, Parc Extension, and Ville - Émard, they became the dominant form of housing during the post-war period . </P> <P> In the 21st century, Montréal has continued to build row houses at a high rate, with 62% of housing starts in the metropolitan area being apartment or row units .
