    Aurora Tree Removal connects homeowners across Aurora, Newmarket, Richmond Hill, and King City with ISA-certified arborist crews.

What we do: - Tree removal: CAD $800–$3,500 per tree (typical) - Stump grinding: from $150 - Tree pruning to ANSI A300 standard: $300–$1,200 - Emergency and storm-damage work, priced by scope How a job runs: 1. You describe the tree by phone, email, or form. 2. We send a free written quote within 24 hours — itemized, fixed-price, with Aurora Bylaw 6362-21 permit fees included. 3. The crew arrives in marked trucks with full PPE. 4. We file the permit, do the work, haul the wood, and clean up. No on-site sales pressure. No drive upcharge for Newmarket, Richmond Hill, or King City. Insurance-claim documentation provided on every storm-damage job. We're honest about the model: we vet partner crews rather than running our own. That's how we keep quality consistent and pricing transparent.
