Canada's oldest railway tunnel was built in the 1850s for the Brockville and Ottawa Railway. Stretching just over half a kilometre, it even pre-dates the Canadian Pacific Railway. Trains stopped running in 1970 and the city bought it later, converting it into a tourist attraction in 2017 with colourful lighting. Pedestrians can walk from one end to the other.
Notice as you walk further in that the tunnel structure changes. The section closest to the waterfront was made using open-cut trenching while the middle section was blasted through bedrock.
Brockville is an hour's drive south of Ottawa.
