April 2014

Explanatory Notes: 

  • The Planning Act Approval Authority chart provides an overview of where planning approval authority rests with respect to the approval of official plans and amendments, subdivisions, condominiums, consents, power of sales and validations, either by being directly assigned in the Planning Act or prescribed or delegated by the Minister of Municipal Affairs pursuant to the Planning Act for municipalities, planning boards and municipal planning authorities in Ontario.
  • The chart includes, in alphabetical order, all 444 municipalities in the province as well as a list of planning boards and municipal planning authorities.  The listing indicates municipalities by type, being upper-tier, single-tier or lower-tier, in accordance with the Municipal Act, 2001.  The chart also identifies the upper-tier or territorial district in which a single-tier or lower-tier is located, where applicable.
  • The chart does NOT show where an upper-tier municipality has in turn further delegated planning approval authority to a lower-tier municipality (eg. the delegation by an upper-tier of subdivision or consent approval to a lower-tier municipality).  The chart indicates when upper-tier municipalities should be consulted for this information.
  • The chart identifies the municipalities whose official plan amendments (OPAs) are exempt from MMAH approval.
  • The chart also indicates when an upper-tier municipality should be consulted for exemption information regarding lower-tier official plan amendments.

    Approval Authority - Upper Tier 

An upper-tier municipality with an approved official plan is the approval authority for lower tier official plans and official plan amendments pursuant to subsections 17(2) and (4) of the Planning Act and for subdivision applications pursuant to subsections 51(5) and (5.1) of the Planning Act. 

Exemption of Official Plan Amendments from the Requirement for Minister Approval  

Subsection 17(9) of the Planning Act provides the Minister the authority to exempt by order an official plan or proposed official plan amendment(s) from his or her approval. (Note - subsection 17(9) does not apply to an official plan amendment made under subsection 26(1) of the Planning Act.)

Ontario Regulation 525/97 (as amended by Ontario Regulation 344/98 and other amending regulations), identifies those municipalities where amendments to official plans are exempt from the approval of the Minister of Municipal Affairs and Housing. 

 Authorization of the Exemption of Lower Tier Official Plan Amendments from the Requirement for Upper Tier Approval 

The Minister, by order pursuant to subsection 17(10) of the Planning Act, authorized upper-tier municipalities to pass by-laws to exempt lower-tier official plan amendments from requiring the approval of the upper-tier municipality.  In these cases, the chart will indicate that the upper-tier municipality should be consulted for additional information on exemption and approval authority.
