Rideau Canal: 12 Unknown & Epic Facts!

Nestled in Canada’s capital city Ottawa, Rideau Canal connects it to Lake Ontario and the Saint Lawrence River at Kingston. The name Rideau is French, which means “curtain.”

This name was designated to the canal due to the twin waterfalls’ curtain-like appearance that empties the Rideau River into the Ottawa River.

Currently, the Rideau Canal is governed by Parks Canada. This canal is much more than just a canal. It has a centuries-old history attached to it, along with a few implications on the way.

However, the Rideau Canal is intact today, holding its history strong and giving the current generations a perfect recreational spot.

Yes, you’re reading it right. The Rideau Canal was originally built as a precautionary measure during the war of 1812 when there were rumors about the US’s plan to invade Upper Canada by following the St. Lawrence River.

The St. Lawrence River bordering the United States was a vulnerable spot, and there was a need to send supplies and reinforcements.

After the war times were over, Rideau Canal was planned to be built and have a military significance, and it received funding through the British Ordinance Department.

The canal received the expertise of Royal Engineers led by Lieutenant Colonel John By. The Rideau Canal was set to connect Montreal with Kingston. The construction work started in 1826.

2) The Historical Construction

The construction of the Rideau Canal was a tough challenge. At that time, the route was mostly wild bush, swamps, and rocky terrains. However, Colonel John was an expert, and he divided the Rideau into 23 different work sections.

There were thousands of local workers hired by independent contractors who were under the supervision of Royal Engineers.

The contractors and local men mainly did the canal’s construction, but Royal Engineers and Colonel himself administered the engineering. Colonel By started by giving small contracts for forest clearing, stonemasonry, and excavation.

All the work in constructing the Rideau Canal was carried out by hand and just human labor. Even the rocks were hand-drilled and blasted with the merchant or black powder.

The 202 km of Rideau Canal with 47 locks is the oldest, continuously operated canal system in North America.

3) The Tragic Deaths

It is believed that lots of workers died during the construction of the Rideau Canal. But the truth is, the deaths were not due to their indulgence in work. Malaria caused most of the deaths that happened at the time.

There is also a myth that the anopheles mosquito that causes malaria was brought to the Rideau workers’ area. However, the truth is, that malaria has existed in the areas since the 1700s.

Due to this problem, there were cemeteries built near each of the worksites. They used to hold a funeral and mark the grave with wooden markers and fieldstones.

Today, the fieldstones remain in the area spreading the myth of mass burial in unmarked graves. Three cemeteries are still intact today, McGuigan Cemetery, Old Presbyterian Cemetery, and the Cemetery at Chaffeys Lock.

4) The Story Behind Parliament Hill

During the Rideau Canal construction period, there was remarkable growth in the settlement on the south side of the Ottawa River.

Colonel By surveyed the streets and lots, and eventually, the community was known as the Community of Bytown. Today Bytown has been known as Ottawa since 1855.

At the time of construction, the Royal Sappers and Miners needed a proper place to rest in. For them, barracks were built on Barrack Hill. It was a site for military bases during the 18th and 19th centuries.

They’d planned a large fortress on the site but was never built, and after the completion of the Rideau Canal, Barrack Hill lost its significance.

However, in 1858 when Ottawa was selected as the Capital of Canada, Barrack Hill was selected to be the new parliament building site.

It was eventually renamed Parliament Hill and has been a National Historic Site of Canada since 1976 and attracts around 3 million visitors each year.

Who knew that the Barracks constructed for military and residence purposes by Rideau Canal Constructors would become a National Significance spot?

5) The Locks of the Canal

Most of the historical construction of the canal is intact even today. Such was the power of architecture and construction in the 19th Century.

At the Ottawa Lock Station, the original Commissariat Building and the Royal Engineers Barracks’ foundation stand tall among the modern buildings.

The canal has fashioned 45 locks operated at 23 lock stations along the length of the canal. Among these locks, most of them are still hand-operated.

There are two other locks at the entrance of the Tay Canal. There are four blockhouses on the sides of the locks and 16 lockmaster residences along the waterway.

The canal’s lock system is fully functioning, and the gates of the locks allow boats in and out. The Commissariat Building on the Ottawa Locks is the oldest stone building still erect in Ottawa. It was built in 1827 as a storehouse for the British Military.

6) The Gates of the Locks and a New Lock

The lock gates are said to last 12-15 years, but the original gates of Rideau Waterway lasted quite more than that. Carpenters and blacksmiths made the Original Gates at the site of the lock itself.

Today, they’re made in Smith Falls. It takes around two months to build the gates of the canal.

The Gates of Rideau Canal Locks are made of Douglas Fir only and are miter-shaped to ensure a tight seal due to water pressure. Approximately 1.3 million liters of water are used by the lock lift of the Rideau Canal.

In 1973-74, Smith Falls Combined Lock was built that bypassed locks 28-30. One lock to the north of the original three locks was termed much more useful.

7) The Early Commercial Purpose of the Rideau Canal

As originally designed for military purposes with six blockhouses, the canal’s primary use was entirely Commercial. It became the most preferred water route to Montreal.

The canal, there were majorly two benefits. The difficulty and shipping costs from Ontario were reduced significantly. It became a part of the regional transportation system.

There are several dams on the canal that are used for generating Hydroelectric Power.

8) The Recreational Usage of the Canal

As there were developments in the shipbuilding industry, more powerful steamships were built to navigate the unimproved section of the St. Lawrence River.

As a result, the traffic on the Rideau Canal started dropping. By the early 20th Century, the purpose started to shift from commercial to recreational.

Many cottages and lodges were built along the canal, and the lakes became a hotspot for bass fishing. There were talks of shutting the canal, but the growing recreational use stopped this decision.

Many summer and winter activities started developing, and locals and tourists would even like to observe the working of hand-driven lock lifts.

10) The Largest Skating Rink

Each winter, the Rideau Canal becomes the Rideau Canal Skateway and, thus, obtains the title of the largest skating rink in the world.

Isn’t it interesting? The thought of turning the canal into a skate way was put forward by the then-newly appointed chair of NCC, Doug Fullerton.

Around 1971, the NCC team armed with their weapons of brooms and shovels converted his thought into reality.

It was a six-meter-wide skating track, and the area between the bridges was set to mood by the addition of lighting and music.

That year thousands of people enjoyed the winter fun, and since then, it has been a key site for Winterlude celebrations.

Today’s skate way is winding about 7.8 kilometers, and the skating season lasts for an average of 50 days. To add to your amazement, the record for skating season lasting is of 95 days!
