The transition to autumn continues across Central Ontario and even into the Dundalk Highlands and Durham region. Mono Cliffs (near Orangeville) and Darlington (near Oshawa) report that around 10% of the leaves have begun to change colour. This is in addition to parks through the Algonquin, Lake Simcoe, Lake Huron and Ottawa Valley regions that have previously reported a colour change of around 10%.
The data for parks in the Muskoka and Simcoe County regions has not been updated since late August so it’s possible that colour change is also ongoing there. Once we have solid data that indicates that, we will update the map.
Fall Colour Report by park
| Park Name | Colour Change (%) | Tree Coverage |

| Algonquin | 10% | 100% |

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.
