High water levels at Thousand Islands National Park 

Updates: openings and closures

May 16, 2017, Mallorytown, Ontario

Thousand Islands National Park is opening for the 2017 season on Saturday May 20th. Parks Canada staff has been hard at work the past two weeks to ensure Thousand Islands National Park will be able to provide opportunities for Canadians to visit the park as the Canada 150 celebration season is launched. With water levels on the St. Lawrence River approximately 3 feet higher than normal, some park services continue to be affected by the rain and flooding that have impacted Ontario and Québec this month.

Public safety is a priority for Parks Canada. Although Thousand Islands National Park is opening as many areas as possible, access to some facilities must remained closed to visitors. These closures include the boat launch and two oTENTiks at Mallorytown Landing, some island areas, and some docks within the park. Parks Canada is responding as required to changing conditions and re-opening areas as soon as it becomes safe to do so. 

For non-boaters staying overnight, 8 out of 10 Parks Canada oTENTiks are currently open to visitors, and 47 out of 62 island campsites continue to be available. Parks Canada is actively working to notify all individuals who have reserved an oTENTik or campsite during the month of May to provide current conditions in the park. 

High water can be dangerous and we encourage all members of the public to be careful and vigilant around the edge of the river, where there may be hidden hazards and strong currents, and to take extra care looking out for possible debris in the water and changing river conditions. 

Travellers should review the list of services and facilities available here prior to travel. Parks Canada is reviewing and updating information on a daily basis. Visitors can also follow current park conditions on Facebook, or on Twitter @TInationalpark
