Brockville Railway Tunnel

Discover Canada’s first and oldest train tunnel, the unique Brockville Railway Tunnel, which stretches underneath historic Brockville’s downtown district. Built between 1854 and 1860, steam and wood-burning trains operated by the Brockville and Ottawa Railway used the tunnel as a regional link for over 110 years. It connected Brockville’s bustling industrial waterfront with the rural areas between the St. Lawrence and Ottawa Rivers. Eventually, the train route stretched to Montreal. 

The tunnel’s construction was impressive for its time, predating both the Canadian Pacific Railway and the famous rail tunnels in the Western Rockies. Engineers constructed the tunnel with stone and water lime, which created colourful mineral deposits along the walls. The entrances feature limestone rock and unique solid wood doors. 

The tunnel extends 525 metres long, from Water Street near Armagh Sifton Price Park by the bank of the St. Lawrence River to its northern exit just past Pearl Street. Today, visitors can walk through the tunnel and enjoy its consistently chilly year-round temperature of 13 degrees celsius. Admission is free and the attraction is open throughout the year, seven days a week. Donations are welcome at the red donation boxes that are located at the entrance and exit of the tunnel. The donations help cover the maintenance cost of the tunnel. From the beginning of April through the end of November, you can enjoy public tours of Brockville Railway Tunnel. 

Walking through the tunnel is a unique experience. A series of colourful LED lights fade and glow while highlighting the architectural and engineering heritage. It features 735 light fixtures and a modern sound system. Several benches along the walls provide places to rest, and different panels offer stories of area history, geology and construction. You’ll find proper ventilation, security, safety features, accessibility and public WiFi access throughout the tunnel. 

Located underneath the historic core in the centre of Brockville, the Brockville Railway Tunnel is about halfway between Kingston tothe south (83 km) and Cornwall to the north (102 km) via Highway 401.
