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 notes that while temperatures have dropped recently, it might be too late for the physiological process that triggers trees to change their colours.
Daylength, tree species and weather conditions are three key factors that determine the colour of autumn leaves.
