City of Ottawa
On January 1, 2021, the City of Ottawa consolidated by-laws 2009-200 (Urban Tree Conservation By-law) and 2006-279 (Municipal Trees and Natural Areas Protection By-law) into their new Tree Protection By-law (2020-340). The by-law applies to municipal trees and municipal areas in the City of Ottawa and trees on private property in the urban area of the City of Ottawa.
Changes to the by-law include the size criterion for “distinctive” trees, which has been reduced from 50 cm to 30 cm in diameter breast height (DBH) for trees located within the City’s inner urban area. See here for more details.
