La Plaine
In the mid-1600s the first of 3 seigneuries (Repentigny, 1647; Des Plaines, 1731; and Lachenaie, 1752) was granted in the area, but the first settlers did not arrive until 1760-65. In 1877 the Laurentian Railway between SAINTE-THÉRÈSE and Saint-Lin was completed but development remained slow.
