Open House Notice: City Initiated Zoning By-law Housekeeping Amendment


The City of St. Catharines is reviewing its Zoning By-law and conducting a Housekeeping Amendment. The purpose is to address recent changes to the Planning Act by the Government of Ontario, amend policies to improve interpretation and application, and to correct grammar, punctuation and formatting.

The key elements of the Amendment include:

  • Permissions for two additional residential units (accessory dwelling units) within detached, semi-detached, or townhouse dwellings, including size, height, setbacks, and parking. This includes updated standards for detached accessory dwelling units.
  • Updating definitions for lot lines, yards, and encroachments, such as decks, patios, and porches (platform structures).
  • Revising parking space dimensions, bicycle and accessible parking requirements and introducing parking area requirements, such as minimum drive aisle widths.
  • Definitions relating to landscaped open space and landscape buffers and inclusion of maximum hard landscaping coverage.
  • Inclusion of a transition clause, updated page numbers, revised section numbers, and other various formatting elements.

Amendment materials are available for review and comment online at or in person at the Planning and Building Services Department at City Hall, 50 Church Street, St. Catharines.

The information currently available is preliminary.  Additional revised, or further refined information will be loaded to the project page at the link above as it becomes available.

The City will host a drop-in style Open House, where materials will be available for review and staff will be present to receive comments and answer questions.
