Ontario and Quebec are the most impressive
From mid-September, the foliage in Canada's forests begins to glow in all shades of purple, vermilion, gold, and copper. Indian summer is just around the corner. The splendor of this riot of color in the vast forests is incomparable. The color spectacle is most impressive in the eastern states of Ontario and Quebec. As a rule, the leaves change color first in mountainous areas and in the north. Then the phenomenon spreads southward. A single freezing night is enough to ignite the fireworks of colors. The blaze of color lasts until late October. Then the
trees lose their leaves, and soon their branches are covered with snow.
