7) Ile Ganon, Quebec
Owner: Celine Dion – Net worth: $400 million
“My Heart Goes On,” which is known to be one of the greatest hits worldwide, and an all-time favorite with music lovers around the world, had been crooned by the melody queen Celine Dion which has eventually made her one of the highest paid performers the world over. Befitting the diva, she acquired an island in the home province of Quebec, located on the sleepy Iles River, giving her opportunities to take the much needed breaks from her hectic schedule. The island houses her imposing mansion, the details of which are still unknown, due to the strict security arrangements. The closest one can get is by boat rides.
