A secondary plan is a detailed planning document for a specific area within a municipality, providing more detailed policies than the broader Official Plan. Secondary plans typically cover neighbourhoods, growth areas, downtown cores, or areas undergoing significant change. They establish detailed land use designations, densities, building heights, transportation networks, park locations, and design guidelines specific to that area. Secondary plans must conform to the Official Plan but add precision for local planning decisions. Development applications in areas with secondary plans are evaluated against both the Official Plan and the more specific secondary plan policies.
