The painting captures the essence of the Canadian winter landscape, with its subdued palette of whites, blues, grays, and muted earth tones. Hennessey's work is known for its emotive quality and his ability to convey the starkness and solitude of winter.

The composition focuses on the contrast between the snow-covered ground and the dark, dense forest that looms in the background. The trees are rendered with vertical brushstrokes that convey their height and the verticality of the cliffs, suggesting the rugged terrain of the Laurentians. The foreground features snowdrifts and rocks, partially covered with snow, adding to the scene's depth and realism. The sky is overcast, with the clouds hanging low, which adds to the painting's overall feeling of coldness and the weight of winter.

Hennessey's technique, with its thick application of paint and textural contrasts, gives the piece a tactile sense. It allows the viewer to almost feel the coldness of the air and the silence of the snowy landscape. Winter in the Laurentians is more than just a landscape; it is a sensory experience. It invites contemplation and immerses the viewer in the quiet and introspective atmosphere of the Canadian winter. It is a testament to Hennessey's skill in capturing the spirit of a place and a season through his art.
