⚠️ Important: City of Ottawa Tree Protection By-law (No. 2020-340)

Before cutting down any private tree in Ottawa, know the law: inside the urban boundary, any tree measuring 30 cm DBH (Diameter at Breast Height) or larger on lots under 1 hectare requires a City of Ottawa Distinctive Tree Permit and an official ISA Certified Arborist Report. Fines for unpermitted removal range from $500 to $100,000. Read our complete 2026 Ottawa Tree Permit Guide →
