Sugar Island is located in the Thousand Islands region of the St. Lawrence River in the United Counties of Leeds and Grenville, Ontario. It is roughly 43 acres (170,000 m²) of undeveloped island wilderness. In the 1950s the local nautical charts changed the name from St. Lawrence Island to the name the island has now, Sugar Island. In the late 19th century the island was inhabited the year round by a farming family, and the maple trees were tapped for syrup, which gave Sugar Island its current name. The American Canoe Association holds its annual meet here every summer and has for over 75 years.
