Under Brockville’s downtown core, running 0.5 kilometres (0.3 miles) north and south, is the first railway tunnel built in Canada. Constructed between 1854 and 1860, it allowed the fledgling Brockville and Ottawa Railway to connect the industrial waterfront area to the outlying areas between the St. Lawrence and Ottawa rivers. As part of Digital Doors Open, explore the various stations of the tunnel through interpretive panels, download their handy information guide, and learn more about Brockville’s railway history through the video below.
