Committee of Adjustment

This address's applications to the City's Committee of Adjustment since 2017, and any still open. A minor variance asks for a small exception to the zoning by-law, such as a little more height or a smaller setback; a consent divides a lot or grants an easement.

• Minor variance · New R building

  To legalize and to maintain a second and third storey addition above the existing dwelling and the conversion into a duplex dwelling. This application is being considered as a new duplex dwelling.
