To the delight of merchants, the Carillon Canal - built on the Ottawa River for military purposes - opened in 1833. Located 100 kilometres from Montreal and 130 kilometres from Ottawa, the canal is today a pleasure boating waterway.
You'll be intrigued by the manoeuvres made by boats using the lock, which enables them to navigate a 20-metre drop in only 40 minutes!
Then, head off to explore the former barracks that now house a museum.
