The Rideau Canal, also known unofficially as the Rideau Waterway, connects the city of Ottawa, Ontario, Canada, on the Ottawa River to the city of Kingston, Ontario, on Lake Ontario. It is 202 kilometres in length. The name Rideau, French for "curtain," is derived from the curtain-like appearance of the Rideau River's twin waterfalls where they join the Ottawa River. The canal system uses sections of two rivers, the Rideau and the Cataraqui, as well as several lakes. The Rideau Canal is operated by Parks Canada.
The canal was opened in 1832 as a precaution in case of war with the United States. It remains in use today primarily for pleasure boating, with most of its original structures intact, operated by Parks Canada. The locks on the system open for navigation in mid-May and close in mid-October. It is the oldest continuously operated canal system in North America, and in 2007 it was registered as a UNESCO World Heritage Site.

The construction of the Rideau Canal was a preventive military measure undertaken after a report that during the War of 1812 the United States had intended to invade the British colony of Upper Canada via the St. Lawrence River, which would have severed the lifeline between Montreal and Kingston. The British built a number of other canals (Grenville, Chute-à-Blondeau and Carillon Canals, all along the Ottawa River) as well as a number of forts (Citadel Hill, La Citadelle, and Fort Henry) to impede and deter any future American invasions of Canadian territory.
The initial purpose of the Rideau Canal was military, as it was intended to provide a secure supply and communications route between Montreal and the British naval base in Kingston. Westward from Montreal, travel would proceed along the Ottawa River to Bytown (now Ottawa), then southwest via the canal to Kingston and out into Lake Ontario. The objective was to bypass the stretch of the St. Lawrence bordering New York; a route which would have left British supply ships vulnerable to an attack or a blockade of the St. Lawrence.
The canal also served a commercial purpose. The Rideau Canal was easier to navigate than the St. Lawrence River because of the series of rapids between Montreal and Kingston. As a result, the Rideau Canal became a busy commercial artery from Montreal to the Great Lakes. However, by 1849, the rapids of the St. Lawrence had been tamed by a series of locks, and commercial shippers were quick to switch to this more direct route.
The construction of the canal was supervised by Lieutenant-Colonel John By of the Royal Engineers. Private contractors such as future sugar refining entrepreneur John Redpath, Thomas McKay, Robert Drummond, Thomas Phillips, Andrew White and others were responsible for much of the construction, and the majority of the actual work was done by thousands of Irish and French-Canadian labourers. Colonel John By decided to create a slackwater canal system instead of constructing new channels. This was a better approach as it required fewer workers, was more cost effective, and would have been easier to build.
The canal work started in the fall of 1826, and it was completed by the spring of 1832. The first full steamboat transit of the canal was done by Robert Drummond's steamboat, "Rideau" (aka "Pumper"), leaving Kingston on May 22, 1832 with Colonel By and family on-board, and arriving in Bytown on May 29, 1832. The final cost of the canal's construction was £822,804 by the time all the costs, including land acquisitions costs, were accounted for (January 1834). Given the unexpected cost overruns, John By was recalled to London and was retired with no accolades or recognition for the tremendous accomplishment he'd achieved.
Once the canal was constructed, no further military engagements took place between Canada and the United States. Although the Rideau Canal never had to be used as a military supply route, it played a pivotal role in the early development of Canada. Prior to the locks being completed on the St. Lawrence in the late 1840s, the Rideau served as the main travel route for immigrants heading westward into Upper Canada and for heavy goods (timber, minerals, grain) from Canada's hinterland heading east to Montreal. Tens of thousands of immigrants from the British Isles travelled the Rideau in this period. Hundreds of barge loads of goods were shipped each year along the Rideau, allowing Montreal to compete commercially in the 1830s and 40s with New York (which had the Erie Canal) as a major North American port. In 1841, for instance, there were 19 steamboats, 3 self-propelled barges and 157 unpowered or tow barges using the Rideau Canal.
As many as one thousand of the workers died from malaria, other diseases and accidents. Most deaths were from disease, principally complications from malaria (P. vivax), which was endemic in Ontario within the range of the Anopheles mosquito, and other diseases of the day. Accidents were fairly rare for a project of this magnitude; in 1827 there were 7 accidental deaths recorded. Inquests were held for each accidental death. The men, women and children who died were buried in local cemeteries, either burial grounds set up near work sites or existing local cemeteries. Funerals were held for the workers and the graves marked with wooden markers (which have since rotted away—leading to a misconception that workers were buried in unmarked graves).
Some of the dead remain unidentified as they had no known relatives in Upper Canada. Memorials have been erected along the canal route, most recently the Celtic Cross memorials in Ottawa, Kingston and Chaffeys Lock. The first memorial on the Rideau Canal acknowledging deaths among the labour force was erected in 1993 by the Kingston and District Labour Council and the Ontario Heritage Foundation at Kingston Mills.
Three canal era cemeteries are open to the public today: Chaffey's Cemetery and Memory Wall at Chaffey's Lock—this cemetery was used from 1825 to the late 19th century; the Old Presbyterian Cemetery near Newboro—used from 1828 to the 1940s; and McGuigan Cemetery near Merrickville—used from the early 19th century (c. 1805) to the late 1890s.
The canal has been featured on postage stamps issued by Canada Post. Two 45-cent stamps—'Rideau Canal, Summer Boating at Jones Falls' and 'Rideau Canal, Winter Skating by Parliament'—were issued on June 17, 1998, as part of the Canals and Recreational Destinations series. The stamps were designed by Carey George and Dean Martin, based on paintings by Vincent McIndoe. In 2014, the canal appeared on a $2.50 international rate stamp as part of a Canada Post set honoring World Heritage Sites. The same design was reprised on a 2016 domestic-rate stamp.
In 2007 it was inscribed as a UNESCO World Heritage Site recognizing it as a work of human creative genius. The Rideau Canal was recognized as the best preserved example of a slack water canal in North America demonstrating the use of European slackwater technology in North America on a large scale. It is the only canal dating from the great North American canal-building era of the early 19th century that remains operational along its original line with most of its original structures intact. It was also recognized as an extensive, well preserved and significant example of a canal which was used for military purposes linked to a significant stage in human history - that of the fight to control the north of the American continent.
A plaque was erected by the Ontario Archaeological and Historic Sites Board at Jones Falls Lockstation commemorating Lieutenant Colonel John By, Royal Engineer, the superintending engineer in charge of the construction of the Rideau Canal. The plaque notes that the 123-mile long Rideau Canal, built as a military route and incorporating 47 locks, 16 lakes, two rivers, and a 360-foot-long (110 m), 60-foot-high (18 m) dam at Jones Falls (Jones Falls Dam), was completed in 1832.

The 202 kilometres (126 mi) of the Rideau Canal incorporate sections of the Rideau and Cataraqui rivers, as well as several lakes, including the Lower, Upper and Big Rideau lakes. About 19 km (12 mi) of the route is man-made. Communities along the waterway include Ottawa, Manotick, Kars, Burritts Rapids, Merrickville, Smiths Falls, Rideau Ferry, Portland, Westport, Newboro, Seeleys Bay and Kingston. Communities connected by navigable waterways to the Rideau Canal include Kemptville and Perth.
Today, only pleasure craft make use of the Rideau Canal. It takes approximately 3–5 days to travel one way through the Rideau Canal system by motor boat. Boat tours of the canal are offered in Ottawa, Kingston, Merrickville, and Chaffeys Lock. A cruise line operates the ship Kawartha Voyageur. Recreational boaters can make use of it to travel between Ottawa and Kingston. Most of the locks are still hand-operated. A total of 45 locks at 23 stations are located along the canal, plus two locks (locks 33 and 34) at the entrance to the Tay Canal (leading to Perth). Furthermore, there are four blockhouses and some of the original 16 defensible lockmasters residences along the waterway. The waterway is home to many species of birds, reptiles, amphibians, mammals and fish.
In 1973–74 a new Smiths Falls Combined Lock, 29a, was built a few dozen metres to the north of the original flight of 3 locks (locks 28–30). The original locks were bypassed but left in place.
In normal operations the canal can handle boats up to 27.4 m (90 ft) in length, 7.9 m (26 ft) in width, and 6.7 m (22 ft) in height with a draft of up to 1.5 m (4 ft 11 in) (boats drafting over 1.2 m (3 ft 11 in) are asked to contact the Rideau Canal Office of Parks Canada prior to their trip). In special circumstances a boat up to 33.5 m (110 ft) in length by 9.1 m (30 ft) in width can be handled.
The Rideau Canal uses a lock system that is still fully functioning. The gates that let boats travel in and out of the locks last approximately 12–15 years. When the canal was originally constructed, the gates would be made at the lock sites by carpenters and blacksmiths. Today they are made in Smiths Falls, Ontario, and sometimes take up to 2 months to build 1 set of gates. The gates used on the Rideau Canal are made of Douglas Fir and are mitre-shaped to ensure a tight seal due to water pressure. The average Rideau Canal lock lift uses 1.3 million litres of water.

In winter, a section of the Rideau Canal passing through central Ottawa becomes officially the world's largest and second longest skating rink. The cleared length is 7.8 kilometres (4.8 mi) and has the equivalent surface area of 90 Olympic ice hockey rinks. It runs from the Hartwell locks at Carleton University to the locks between the Parliament Buildings and the Château Laurier, including Dow's Lake in between. It serves as a popular tourist attraction and recreational area and is also the focus of the Winterlude festival in Ottawa. Beaver Tails, a fried dough pastry, are sold along with other snacks and beverages, in kiosks on the skateway. In January 2008, Winnipeg, Manitoba, achieved the record of the world's longest skating rink at a length of 8.54 kilometres but with a width of only 2 to 3 metres wide on its Assiniboine River and Red River at The Forks. In response, the Rideau Canal was rebranded as "the world's largest skating rink". The Rideau Canal Skateway was added to the Guinness Book of World Records in 2005 for being the largest naturally frozen ice rink in the world.
The Skateway is open 24 hours a day. The length of the season depends on the weather, but typically the Rideau Canal Skateway opens in January and closes in March. In 1971–1972, the skating season was 90 days long, which is the longest season so far. 2015–2016 was the shortest Rideau Canal Skateway season, being a mere 18 days long.

Although some residents of Ottawa had been using the canal as an impromptu skating surface for years, the official use of the canal as a skateway and tourist attraction is a more recent innovation. As recently as the 1970s, the city government of Ottawa considered paving over the canal to make an expressway. The federal government's ownership of the canal, however, prevented the city from pursuing this proposal. When Doug Fullerton was appointed chair of the National Capital Commission, he proposed a recreational corridor around the canal, including the winter skateway between Carleton University and Confederation Park. The plan was implemented on January 18, 1971, despite opposition by city council. A small section of ice near the National Arts Centre was cleared by NCC employees with brooms and shovels, and 50,000 people skated on the canal the first weekend. Today the skating area of the canal is larger because of the equipment available for ice resurfacing and 24/7 maintenance crews. The skateway now has an average of one million visits per year. City councillor and author Clive Doucet credits this transformation of the canal with reinvigorating the communities of the Glebe, Old Ottawa East and Old Ottawa South.
Preparation and maintenance
The preparation for the Skateway starts as early as mid-October. At the end of the boating season, the water is drained at the Ottawa locks near Parliament by Parks Canada. Facilities on the ice such as shelters, chalets, and access ramps for vehicles are then installed. Next, “beams are placed at the locks, and the water is raised to skating level.” After this step, the essentials are added such as stairs to access the ice, and hookups for both plumbing and electricity. When the water cools naturally in the winter, the water level begins to lower. When the water begins to turn to ice, the ice crystals rise to the surface as their density is lower than that of water. This forms an ice cap that then becomes the Rideau Canal Skateway. When the canal has built up a sufficient ice thickness, snow is removed from the ice surface and it is flooded in order to make the ice even more thick and smooth. Samples of ice are tested for quality and thickness. When it is safe to skate on, the Rideau Canal Skateway is opened for the season.
The Rideau Canal Skateway is maintained by the NCC (National Capital Commission). The ice is maintained by crews 24 hours a day, seven days a week. The snow and ice shavings are cleared off the surface every day and the ice surface is flooded each night with a “water dispersion machine” (weather permitting) to fill in any cracks that were caused from the ice contracting and expanding. There are approximately 20 holes along the side of the Skateway that serve the purpose of flooding the ice surface to make it smoother for skaters.
Two types of ice can form on the Rideau Canal Skateway, which are “white ice” and “clear ice”. White ice has a milky appearance with air bubbles, and is formed when snow and water mix and then freeze. White ice can also be formed by mechanically flooding the ice surface with water to increase the thickness of the ice cap. The other type of ice is called “clear ice”, which has a colourless appearance and is formed when ice crystals build up below the frozen surface in cold temperatures. If snow accumulates on the ice it can negatively impact the conditions for skating. Snow depresses the ice surface and slows down the formation of ice crystals beneath the surface.
Ice conditions can be classified as very good, good, fair or poor. They are updated twice daily by the NCC. The ideal (“very good”) conditions mean that there are “a limited number of pressure cracks”, the ice is very hard and durable overall, the ice surface is clean and smooth, there are a “limited number of rough areas”, and there is a “very good gliding surface.”
