Prior to European contact, this territory was occupied by the
Weskarini Algonquin First Nation, and recent archaeological searches have uncovered 500-year old Huron and 700-year old Iriquoan pottery vases, suggesting the lake was possibly a meeting place. The first pioneers arrived in this place in 1897, coming mainly from
Saint-Joachim-de-Shefford and
Roxton Falls. The post office opened a year later in 1898, identified under the English name of Sixteen Island Lake. In 1901, the mission of Notre-Dame-de-la-Sagesse was established and became a parish in 1937. In 1914, the Municipality of Lac-des-Seize-Îles was formed by separating from the Township Municipalities of
Montcalm and
Wentworth. Pine Lake, located 1.5 km from Lac-des-Seize-Îles, received its first share of summer vacationers in 1907. A post office, identified as Lac-des-Pins, was serving vacationers between 1922 and 1954. ==Demographics==
