A commemorative wrought iron cross was erected at the site associated with Cartier's claim. The natural environment of Saint-Quentin has remained virtually unchanged. For nearly a century, it was not developed or cultivated. Since 1930, the island has become more important as a destination for recreation. The island belonged at the time to Quebec Savings and Trust Company Limited and the Canada Power and Paper Corporation. The city bid for the land in 1933, but did not take ownership until November 3, 1947. During World War II, it was the site of a training camp for the Royal Canadian Navy. Services were gradually introduced in 1950. The park and the beach on the island Saint-Quentin were officially inaugurated on June 24, 1962, in the presence of 5,000 people. There were more than 100 000 visitors that year. Since then, many facilities have been developed on the island, including a marina, a bike path, an interpretative trail, an ice rink, and camping ground. Several happenings and festivals are held annually on the island.
