NIMBY (Not In My Back Yard) describes opposition to proposed developments or facilities in one's own neighbourhood, even when recognizing the broader community need for such uses. NIMBY opposition commonly targets affordable housing, shelters, group homes, transit projects, landfills, and other developments perceived as negatively affecting property values or neighbourhood character. While residents have legitimate interests in their neighbourhoods, NIMBY opposition can prevent necessary projects and concentrate unwanted uses in areas with less political power. Municipalities manage NIMBY dynamics through transparent planning processes, fair site selection criteria, community engagement, and adherence to zoning and planning policies rather than neighbourhood-by-neighbourhood resistance.
