In 1845, the Métis Amable LeBlanc and his wife Marie-Louise Cimon, the niece of Basile Outik, chief of the Oka Indian tribe, went to settle on an island in the middle of a lake located 121 kilometres (75 mi) north-west of Oka.

[4] The largest island in the lake is now called White Duck Island (Île du Canard Blanc) in honour of Amable LeBlanc who was nicknamed "White Duck" in reference to his slightly lighter skin colour as compared to his native relatives.

[5] Starting in 1852, Franco-Catholic colonists began to settle at the lake, working as log drivers, loggers, or farmers.

[1] Lac-Simon's development as a resort area began in the 1950s, and accelerated when the provincial government acquired sites bordering the lake and opened a campground.
