Description: SINGLE TIER - A single-tier municipality means a municipality that does not form part of an upper-tier municipality for municipal purposes and assumes all municipal responsibilities set out under the Municipal Act and other Provincial legislation. LOWER TIER - A lower-tier municipality means a municipality that forms part of an upper-tier municipality for municipal purposes. Municipal responsibilities set out under the Municipal Act and other Provincial legislation are split between the upper tier and lower tier municipalities. Additional Time Period Information: Updates are done as required. Changes may occur as a result of correction of errors or improvement in positional accuracy, at any time. Additional Documentation Municipal Boundary - Lower and Single Tier - Data Description (PDF) Municipal Boundary - Lower and Single Tier - Documentation (Word) Status On going: data is being continually updated Maintenance and Update Frequency Annually: data is updated every year Contact Paul McKenzie, Paul.McKenzie@ontario.ca
