Brockville Railway Tunnel Doors Open Brockville and Area

Brockville Railway Tunnel
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. Volunteers will be on hand throughout the day.
