The painting depicts a lively autumn scene with a flurry of brushstrokes that vivify the canvas with a rich tapestry of fall colors. The foreground is filled with an array of plants and foliage, painted in a vibrant palette of reds, oranges, yellows, and browns, which capture the essence of the autumnal theme. The leaves and branches are rendered with dynamic, expressive strokes that convey the organic and wild spirit of nature during the fall season.

In the background, the Rideau River appears as a calm presence amidst the burst of fall colors, with hints of blue reflecting the sky. Across the river, one can discern the silhouette of buildings, possibly indicating a small town or settlement, nestled among the trees showing signs of autumnal transformation.

The sky above is painted with soft, muted tones of blue and gray, with gentle strokes that suggest a cloudy, overcast day. The painting's overall effect is a vibrant depiction of the Canadian landscape during the change of seasons, with a focus on the natural beauty and color changes that autumn brings.
