The autumn foliage is becoming more dominant across the Ottawa Valley into Algonquin Park as another milestone in this year’s colour transformation has been reached. This region is the first of the season to hit 20% colour change including parks such as Voyageur, Bonnechere, Lake St. Peter, Algonquin and Mikisew.
There are also some signs that parks around Lake Simcoe are approaching the 20% mark so we will likely see more of Central and Eastern Ontario added to the 20% zone in the next update. Deep Southwestern Ontario including Leamington and Pinery continues to be one of the remaining holdouts with no colour change being reported based on the latest data.
However, Rondeau is now reporting that the colour change has hit the 10% mark so we have added Chatham to the map.
Please note: This forecast relies on extrapolating data collected from various parks throughout Southern Ontario. Since some parks do not provide daily updates, we may draw data from adjacent regions to formulate our estimated leaf change predictions. This also means that the data displayed on the map may not exactly match what is occurring in your backyard.

The ideal time to witness the full glory of fall colours in Southern Ontario is when the colour change percentage reaches its peak, often around 70-90%, and the tree coverage is above 50%.
The peak of fall colours in Southern Ontario typically lasts for about one to two weeks, although the exact duration can vary from year to year depending on weather conditions.
