The Iron Horse Trail is a multi-use urban rail trail which connects the cities of Waterloo and Kitchener, Ontario, Canada. It runs from Erb Street West in the north near Uptown Waterloo, to Ottawa Street South in Kitchener to the south. It covers a distance of 5.5 kilometres (3.4 mi). The trail was opened on 5 October 1997 on abandoned Canadian Pacific Railway right of way sections, including portions of the right-of-way of the now-defunct Grand River Railway. The two cities combined resources to purchase the property. It is a part of the Trans Canada Trail.
