The Charles Sauriol Conservation Reserve lies between the Forks of the Don and Lawrence Avenue East. It includes the Elevated Wetlands, an experimental water purification project at the Forks of the Don sponsored by the plastics industry. Charles Sauriol was born in Toronto, Ontario. He was the youngest of seven children. His father had moved to Toronto in 1882 to work on a project that involved straightening the lower portion of the Don River.
Charles was an 8th generation Canadian. An ancestor of his had emigrated to New France from Brittany in 1705. During his boyhood he camped out in the Don Valley with the 45th East Toronto Troop of the Boy Scouts. At this time the Don was mostly woods and farmland that remained mostly in its natural state. It was during these trips that he fell in love with the outdoors and especially the Don. This inspired his commitment to help protect the Don Valley for future generations.
