Delayed opening of the Carillon Canal

At the Carillon Canal, major work to rehabilitate the structural components of the vertical door is scheduled for this summer, allowing Parks Canada to open the canal to boaters by the end of August 2020.

Suggested route for navigating from Montréal to Ottawa

Boaters travelling from Montréal to Ottawa while the canal is closed will have to take the St. Lawrence Seaway to Kingston and proceed up the Rideau Canal. Take advantage of this considerable detour to admire the magnificent waterways aboard your boat during this seven to eight day journey.
  • Montréal to Kingston: 134 NM – 1 day
  • Kingston to Ottawa: 109 NM – 5–7 days

Montréal to Kingston – 134 NM on the St. Lawrence Seaway

To travel from Lake Saint Louis, west of the Island of Montréal, to Kingston, at the entrance of Lake Ontario, you must navigate the St. Lawrence River and pass through five of the locks of the St. Lawrence Seaway.

You will cross the rapids, dams and power plants of this majestic waterway connecting the Great Lakes to the Atlantic Ocean. This lock system is operated in partnership between the United States and Canada, so you will pass through three Canadian locks and two American locks.

To facilitate your passage and avoid waiting, consult the schedules on the St. Lawrence Seaway website.

List of locks:

  • Lower Beauharnois lock (Canada)
  • Upper Beauharnois lock (Canada)
  • Snell lock (United States)
  • Eisenhower lock (United States)
  • Iroquois lock (Canada)
After passing through the Iroquois lock, you will have approximately 64 NM to sail to Kingston.

Passage to Thousand Islands National Park

As you approach Kingston, you will see the magnificent archipelago of Thousand Islands National Park. Feast your eyes on this beautiful scenery as you travel the 40 nautical miles between Brockville and Kingston.

Enjoy the comforts of your boat by docking at fully serviced islands or tranquil, rustic islands. For the more adventurous, set up a tent with the kids and gather ‘round the fire for marshmallows. Docks are also available at Mallorytown Landing or at one of the municipal and private marinas between Brockville and Kingston.

Plan your visit on the Thousand Islands National Park website.

Kingston to Ottawa: the 109 NM of the Rideau Canal

Rideau canal lock

The last leg of your adventure will take you along the Rideau Canal from Kingston to Ottawa. This historic canal dating from 1832 is one of Parks Canada’s historic canals. It contains 47 locks along its 109 NM (202 km). It will take you five to seven days to pass through these 24 lockstations. You can moor overnight in the locks and spend the night in your boat or sleep at one of the many campsites. The Rideau Canal is a boater’s paradise. Imagine yourself cruising against a backdrop of country life, sandy beaches and Victorian towns linking a chain of scenic rivers and lakes. 


Your journey will end at the gates of the National Capital with a view of Parliament Hill. You will surely be moved by the sight of these eight step locks that will give you access back to the Ottawa River.
