High water levels at Thousand Islands National Park 

Updates: openings and closures

Some park services continue to be affected by the rain and flooding that have impacted Ontario and Québec in 2017.

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. Parks Canada is responding as required to changing conditions and re-opening areas as soon as it becomes safe to do so. We ask all visitors to plan ahead and be prepared.   

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. The use of closed docks is prohibited as it is unsafe and can cause further damage to the dock and to vessels. 

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