Evidence of human occupation of the islands dates as far back as 500 BCE. Until around 1500 CE, the
St. Lawrence Iroquoians used Île Grosbois as a seasonal hunting ground. Following the arrival of Europeans on the continent, the islands became part of
New France and were offered to
Pierre Boucher in 1664 as part of his acquisition of the seigneury of Boucherville. They were then used as agricultural land. In 1910, an amusement park named after the recently deceased
King Edward opened up on Île Grosbois, only accessible by boat. In the summer, it offered rides, kiosks, dance halls, a racetrack for
horse racing,
roller coasters, and
carousels. In the winter, meanwhile, it offered horse-drawn carriage rides. The same year of its opening, the park hosted Canada's first
aviation competition, attracting noted aviators
Jacques de Lesseps, who used the park to build and repair airplanes, and
Louis Blériot, who ran test flights on the island. In 1928, the collapse of a pier killed several people, spelling the beginning of the end for the park. Competition from Montreal's other amusement parks, namely
Dominion Park and
Belmont Park, eventually caused the closure of King Edward Park in 1928. In 1967, the islands finally became accessible by road following the construction of the
Louis-Hippolyte Lafontaine Bridge–Tunnel. Amidst the ensuing conflict between real estate developers and environmental protection groups, the provincial government decided to purchase five of the Boucherville Islands in the mid-1970s for $7 million. Île Sainte-Marguerite underwent further development starting in 1981 in order to open it up to the public for recreational use. On September 12, 1984, the park officially opened and was inaugurated under the name of
Parc de récréation des Îles-de-Boucherville (Boucherville Islands Recreational Park). In January 2007, a real-estate developer purchased 20.6 hectares of land on Île Charron and began drawing up plans to build apartment towers on the site. Following fierce public opposition, the Quebec government expropriated the plot of land in November of that same year, turning it into a public reserve and forestalling construction for at least two years in doing so. Quebec would later go on to purchase those same 20.6 hectares in 2011 for $15 million and annex the newly acquired land to the Îles-de-Boucherville National Park. In 2010, Sépaq announced that it intended to desist entirely from agriculture, opting instead to reforest the fields or leave them fallow, as the case may be. == Administration ==
