The Rideau Canal: History, Geography, and its significance to Ottawans

By: Siobhan Rollo

 

Overview


For travellers and locals alike, there’s one landmark that truly makes Ottawa what it is, and that is the iconic Rideau Canal.


The construction of the Rideau Canal began in 1826 and finished in 1832, which was the same year it became open for use. During its construction period, just over 1,000 workers lost their lives while working on the project, and were buried along the canal as tribute. 


The Rideau Canal is the oldest continually operated canal system in North America, and has had many “lives”. While initially used in times of war, Ottawans now recognize it as a source of leisure and fun. Each Winter, people from across Canada congregate on the Rideau Canal Skateway as a way of visiting Ottawa. 


Known previously for its crucial use in Canadian history, UNESCO recognized the Rideau Canal as a World Heritage Site in 2007.


While the entire canal is 202 kilometers and takes approximately 4 to 6 days to boat across, Ottawa’s Rideau Canal Skateway can be completed in an hour! 

Three Uses over Many Lifetimes


The Rideau Canal has had three eras; first serving as a military waterway which allowed for a secure transport of supplies from Montreal, QC all the way to Kingston, ON. It was used as an alternative to the St.Lawrence River during the instability that followed after the War of 1812. 


Its second life was its use as a commercial waterway. As times of war slowed to a decline, it was used to transport timber, potash, iron ore, phosphate, and other minerals essential to the construction of what would become parts of Montreal, England, and the United States. Its use was mostly local following the introduction of railroads for commercial transportation. 


Its third life, which is how we recognize the Canal today, is a prominent historical site, a recreational attraction accessible both by land and water, and a World Heritage Site!


The Artery of Ottawa


The Rideau Canal occupies the heart of Ottawa, connecting neighbourhoods all the way from the downtown core to the locals of smaller neighbourhoods, such as the urban Glebe or the cozier Old Ottawa East.


While it serves as a tourist attraction, seeing millions of people every year, it’s a common spot amongst locals as well.


During the summer, Ottawans can be seen walking or cycling along the canal. It’s also a popular spot for bird watching, as Canadian geese and ducks often frequent the water.


During the winter, skating begins! The canal often features little shops and cafes along the skateway for patrons.


Not interested in the water? There’s something for you too! Boat tours and history lessons are available at the locked gateways down by the Canadian Parliament. 


The Rideau Canal serves as the main artery of Ottawa, allowing for good times for locals and tourists alike, offering a rich and valuable history to the city it occupies.
