Registered in the Guinness World Records! Canada’s World Heritage Site – The Rideau Canal

The Rideau Canal, which stretches approximately 202 kilometers from Canada’s capital Ottawa to Kingston, is the oldest canal in North America, having opened in 1832. Originally constructed as a military transport route during the War of 1812 between the United States and Britain, it is now a cherished symbol of Ottawa and a favorite recreational area for residents.
The Rideau Canal offers breathtaking views throughout the year: tulips in spring, fresh greenery in summer, vibrant autumn foliage, and a snow-covered landscape in winter. Because of its year-round beauty, it attracts around one million tourists from all over the world annually—making it an unmissable destination!
Now, let’s take a closer look at the highlights and appeal of Canada’s World Heritage Site, the Rideau Canal.

What is the Rideau Canal?

The Rideau Canal, a UNESCO World Heritage Site in Canada, is a waterway that connects the nation’s capital, Ottawa, with the historic city of Kingston on the shores of Lake Ontario. Spanning a total length of 202 km, the canal was constructed over six years starting in 1826, with more than 2,000 workers involved. The project was overseen by Colonel John By of the British Royal Engineers.
At the time, Canada was a British colony, and in preparation for a possible recurrence of the War of 1812 with the United States, Britain began building fortifications to protect its territory. The Rideau Canal was one such fortification, intended to serve as a military supply route to avoid the vulnerable St. Lawrence River. Although it was never used in war, it played a crucial defensive role and has become a historic symbol of Ottawa.
The Rideau Canal is also the oldest continuously operated canal system in North America. Its lock system, based on early 19th-century European engineering, still operates manually today, which contributed to its UNESCO designation in 2007.
While it never fulfilled its intended military role, the canal has protected Ottawa for more than 180 years and stands as a vital part of the city's history. Today, it is both a popular tourist attraction and an essential thoroughfare for residents. As you float leisurely along its waters, you can enjoy Ottawa's timeless charm.

Access to the Rideau Canal

From Ottawa International Airport, it takes about 30 minutes to reach downtown by bus or taxi. The Rideau Canal flows southward from the Ottawa River, dividing the city into east and west sections. The ByWard Market commercial area is on the east side, while the west side is downtown. The canal itself is a great landmark for orientation while exploring the city.

Highlights of the Rideau Canal

World’s Longest Skating Rink

Depending on the season, there are different ways to enjoy the Rideau Canal. In the warmer months of spring and summer, boating and canoeing are popular. In autumn, you can stroll along the canal while admiring Canada’s vibrant foliage. But winter unveils a unique charm—when the canal transforms into the world’s longest skating rink, as recognized by the Guinness World Records.
This natural ice rink spans about 7.8 km and forms between early January and early March. Locals even use it for commuting to work or school with their own skates. Access is free, and skate rentals are available for tourists. Facilities such as restrooms, changing rooms, cafes, and rest areas are located along the rink. Also, don’t miss the “Winterlude” festival, North America's largest snow festival, held every late January.

The Lock System

Another must-see feature of the Rideau Canal is its lock system. The waterway rises about 50 meters from Kingston and then descends approximately 80 meters to Ottawa. To navigate this elevation change, 47 locks (referred to as "locks") have been built.
The canal is managed by Parks Canada, and the locks are operated manually by staff known as “lockmasters.” During the boating season, they are stationed at “lock stations” and operate the mechanisms by hand to allow boats to pass—just as they did back in the 19th century. Watching this traditional process in action while strolling along the canal is a unique experience.

◎ Summary

Ottawa, with its seasonal beauty and rich history, is not only the capital of Canada but also a top travel destination. Its winter attractions, especially the Winterlude festival and canal skating, are globally renowned. For those visiting during warmer months, the Rideau Heritage Route that runs alongside the canal offers a scenic drive connecting Ottawa and Kingston, featuring visitor centers and fishing spots along the way. Whether you visit in snow or sunshine, the Rideau Canal offers a memorable Canadian experience.
