Experts say warmer than normal temperatures are leading to duller fall colours in Ontario this year.
McMaster University Biology Professor Susan Dudley says a combination of sunny and cold weather really promotes bright fall colours.
She note that while temperatures have dropped recently it might be too late for the physiologic process that triggers trees to change their colours.
Daylight tree species and weather conditions are three key factors that determine the colour of Autumn leaves.
