The Lachine Canal was built in 1825 as a means of bypassing the Lachine Rapids on the St. Lawrence River. Closed to shipping since 1970, the Lachine Canal National Historic Site now offers a 14-kilometre (8.7-mile) bicycle and pedestrian pathway. Since 2002, the Canal has been open for navigation. The Lachine Lock Visitor Service Centre (500 des Iroquois Road) presents a permanent exhibition on the Lachine Canal.
