Blainville is an off-island suburb of Montreal located in southwestern Quebec, Canada. Blainville forms part of the Thérèse-De Blainville Regional County Municipality within the Laurentides region of Quebec. The town sits at the foot of the Laurentian Mountains and is located 25 kilometres (16 mi) northwest of downtown Montreal.
Louis de Buade de Frontenac granted a vast territory that includes present-day Blainville to elite members of society, lords ("seigneurs") or seigneurs, to promote the development of New France in 1683. The Seigneurie des Mille Îles (Lordship of the Thousand Islands) encompassed over 200 square kilometres (77 sq mi) along the northern shores of the Mille Îles River.
In 1792, a disagreement between Seigneur Hertel and Seigneuresse Lamarque resulted in a division of the seigneurial territory along what was then-called the Great Line (present-day Boulevard du Curé-Labelle or Quebec Route 117).
Blainville is named for the third lord of the seigneurie, Jean-Baptiste Céloron de Blainville (1660-1756).
On 14 June 1968, the parish of Sainte-Thérèse-de-Blainville was divided, and Blainville formed its own town consisting of mostly heretofore undeveloped land. In 2017, the municipality governed 54.62 square kilometres (21.09 sq mi) subdivided into eleven districts, maintained an independent police force with a budget in excess of 14 million CAD and more than 110 staff, a fire department with over 70 firefighters, who since 2016 also serve the neighbouring municipality of Rosemère,, a library with three branches, an arena with two rinks, and an aquatic recreation centre.
As of the Canada 2016 Census, Blainville had a population of 56 863, a 6% increase from the Canada 2011 Census., and 21 006 private dwellings. Over 20% of residents are under 15, whereas 69% are between 15 and 64 and 11.6% are over 65.
The 2016 census found that 89% of residents spoke French as (one of) their mother tongue. Although almost 55% of the residents reported knowledge of both English and French, English was the mother-tongue of only 3.6% respondents. The next most frequent mother tongues were Arabic, Spanish, and Portuguese, representing less than 2% of respondents each.
