Boyd Conservation Area is more than a stretch of green space in Woodbridge, Vaughan. Spread across the Humber Valley, it protects part of a long standing natural corridor in the Greater Toronto Area, shaped for generations by the Humber River. Opened in 1957 by what is now the Toronto and Region Conservation Authority, the site spans roughly 4 square kilometres. It was created partly to preserve valley lands and reduce flood risks following Hurricane Hazel.
