Statistics of the Rideau Canal

For all you number hounds out there, here are the statistics on the Rideau Canal System. Please note that in most cases I've separated out the Tay Canal (Beveridges Locks) from the Rideau Canal. On this page you will find information about general Rideau Canal Statistics, information about Rideau Route Statistics, and information about 2015 and 2014 Vessel Passage Statistics.

Rideau Canal Statistics

Lock Dimensions (1)41 metres/134 feet long by 10 metres/33 feet wide
Available Water Depth (2)1.5 metres/5.0 feet (minimum)
Minimum Bridge Clearance (3)6.7 metres/22.0 feet (minimum)
Total Locks (Kingston - Ottawa)45 (47 including the 2 locks on the Tay Canal)
Total Lockstations23 (24 including Beveridges on the Tay Canal)
       See "How the Locks Are Counted" below
Total Distance (Kingston - Ottawa) (4)202 kilometres/125.6 miles
Total Distance of Artificial Channels19 kilometres/12 miles
Lift - ascending Ottawa to Upper Rideau Lake83.8 metres/275 feet (in 31 locks)
Lift - descending Upper Rideau to Kingston50.6 metres/166.2 feet (in 14 locks)
Maximum Size of Vessel (5)27.4 m/90 ft. length, 7.9m/26 ft. width, 6.7m/22ft height
Transit Time (one way)4 to 6 days
Maximum Depth of Water100.3 metres (329 feet)




(1) This is the full length of the lock from the point of the upper sill to the point of the lower sill. The lock is actually 124 feet (37.8 m) long in the chamber, measured from the point of the lower sill to the face of the breastwork. The lower gates require 13 feet (4.0 m) of room for their swing, so a vessel must be less than 111 feet (33.8 m) long. Since the walls of the lock slope inwards, the internal width at the lower navigation water level in the locks is 31.5 feet (9.6 m).

(2) Normally the locks are maintained with a draught of 1.7 metres (5.5 feet). However even the 5 foot minimum is subject to water availability and all vessels with a draught of over 1.2 metres (4 feet) should contact the Rideau Canal Office prior to traversing the canal.

(3) This is the minimum fixed bridge clearance on the Rideau Canal proper. On the Tay Canal, the Craig Street fixed bridge, at 2.1 metres/7 feet limits boats going right into downtown Perth (larger boats can tie up at Last Duel Park near downtown).

(4) Distances reflect the Rideau Canal proper. The Tay Canal, which is connected to the Rideau, extends from Lower Rideau Lake to Perth, a distance of 10.0 kilometres (6.2 miles). Two locks (Beveridges #33 & Beveridges #34) raise boats a total of 7.0 metres (22.9 feet) into the Tay Canal.

(5) The Canal used to allow boats with a length of 33.5 metres (110 feet) and a width of 9.1 metres (30 feet) width to traverse the system. If your vessel is less than these dimensions, but greater than the maximum shown in the chart, contact the Rideau Canal Office .


How the Locks Are Counted

When the canal was opened in May, 1832, there were 47 masonry locks that provided navigation from Kingston to Ottawa. In reality, only 46 locks actually provided the navigation since one of the two locks at Hogs Back was (and still is) a guard lock (a flood guard, it normally doesn't provide any lift). But that is picking nits, so we'll leave the count at 47. In the late 1880s, two locks (Beveridges) were constructed at the entrance to the Tay Canal. Although not part of the Rideau Canal proper, they are administered by the Rideau Canal Office - so although the number of locks required for Kingston to Ottawa navigation didn't change, administratively, 2 more locks were added (total 49). In the 1970s, a new single lock (29a) replaced the flight of 3 Smiths Falls Combined locks. This reduced the actual number of Kingston to Ottawa navigation locks to 45 and the total locks administered by the Rideau Canal Office to 47. This is the situation today.

In terms of Lockstations, the present day Kingston to Ottawa navigation lockstations number 23 - they are: Ottawa (8 locks in flight), Hartwells (2 locks in flight), Hogs Back (1 lift lock, 1 guard lock), Black Rapids (1 lock), Long Island (3 locks in flight), Burritts Rapids (1 lock), Nicholsons (2 detached locks), Clowes (1 lock), Merrickville (3 detached locks), Kilmarnock (1 lock), Edmunds (1 lock), Old Slys (2 locks in flight), Smiths Falls Combined (1 lock), Smiths Falls Detached (1 lock), Poonamalie (1 lock), Narrows (1 lock), Newboro (1 lock), Chaffeys (1 lock), Davis (1 lock), Jones Falls (3 locks in flight, 1 detached), Upper Brewers (2 locks in flight), Lower Brewers (1 lock), Kingston Mills (3 locks in flight, 1 detached). The lift statistics for those locks can be seen in the next section.

Parks Canada quotes 24 lockstations since they are counting in the Beveridges (2 detached locks) on the Tay Canal.

Rideau Canal - Locking Statistics

Canal traffic in 2019 was essential flat (up 0.2%) comparted to 2018 with a total of 61,145 vessel passages recorded through the locks, compared to 61,048 vessel passages in 2018. This despite the addition of new boats to the Le Boat fleet, indicating that private boat usage of the canal continue to decline. There are various reasons for this, the most significant is the lack of marketing of the Rideau Canal by Parks Canada to the boating public.

These numbers represent the cumulative total of vessel passages through the locks (divide by 8 to get the approximate number of individual boats).

The table below shows statistics for some selected locks along the canal:

In total during 2019, 65.8% of the boats were from Ontario, 23.9% from Québec, 8.8% from the United States and 1.5% "Other". In absolute terms, boats from Ontario continue to decrease (40,210 vs 41,404) as did boats from the U.S. (5,410 vs 5,650). This was offset by an increase in boats from Québec (14,600 vs 13,350). The big Ontario decrease is mainly due to local boaters who used the locks in 2017 with free lockage, but did not in 2018 with the return of lockage fees.

Moorings increased by 1.5% in 2019, with 11,232 moorings compared to 11,637 in 2018.

Vessel Passages

The chart above shows yearly vessel passages from 1980 to 2019. The big jump in 1982 was due to publicity surrounding the Rideau 150 celebrations. That same level of publicity wasn't achieved for Rideau 175 which saw a much more modest increase in boaters. The large declines appear to be mostly due to uncertainty about the operation of the canal including closures of all or part of the canal. In 1983, the Ottawa locks were closed for repairs. In 1991 and 2004 the union went on strike, closing the canal. Fee increases have a negative impact, but these tend to be much smaller than the effect of canal closures. The jump in 2017 was due to free lockage (tempered by bad weather). Although 2018 showed a decrease, those numbers were bolstered by the first year of operation of Le Boat's 16 rental boats.

The decline from 2009 to 2014 appears to be mostly due to lack of marketing to boaters by Parks Canada (Parks Canada changed their Rideau Canal marketing strategy in 2007/2008) and the lack of adaptability to new boating trends. The uncertainty over the season of the canal, radical fee proposals, and the reduction of hours in 2013, continued the precipitous decline to 2014. The restoration of 1 summer hour in 2014 (although still not to pre-2013 hours) plus good boating weather in both 2015 and 2016 helped provide a modest rebound. 2017 is an anomaly due to the free lockage (which resulted in a large increase in use by local boaters). 2017 did show that local boaters are very fee sensitive and represent a large lockage resource untapped by Parks Canada. 2018 and 2019 show the continued decline in private boaters - the numbers were sustained at slightly above 2016 levels by Le Boat's new Rideau Canal operation with 16 rental boats in 2018 and 20 in 2019.
