“

I have been dealing with Bruce Tree for years and was pleased to experience the same high quality work from C&M after the merger. Arborist Ray was so helpful in suggesting approaches to pruning large trees on my small city lot and accommodating requests from adjoining neighbours. The team was on time, quick, friendly, attentive to tree health and aesthetics. Watching them work was like a morning at Cirque du Soleil. Definitely recommend. 2026 update: C&M and arborist Ray are my go-to for mainte
