General Governance and Administration Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

In Mississauga, Ontario, lot line changes and boundary adjustments are handled through the municipal planning process and may require Committee of Adjustment consent or other approvals. This guide explains the typical steps, who enforces rules, how property impact notices work, and what owners should file to complete a legal boundary adjustment.

Start with a pre-consultation at the city planning office to avoid delays.

Understanding boundary adjustments

Boundary adjustments (lot line changes) can change parcel sizes without creating a new lot, but often still need formal approval because land registration and zoning implications must be addressed. Applications commonly require a plan of survey, owner authorization, and may trigger conditions such as variances, easement registrations, or municipal servicing updates.

Process for boundary adjustments

  • Pre-application consultation to identify requirements and constraints.
  • Submit a consent application to the Committee of Adjustment; supporting documents include survey, sketch, and owner authorization. See the Committee of Adjustment application link below for submission details. Committee of Adjustment - Consent application[1]
  • Notice and circulation to neighbours and municipal departments; the committee reviews planning and technical issues.
  • Decision by the Committee of Adjustment: approvals may include conditions such as registering deeds, easements, or obtaining permits.

Penalties & Enforcement

Enforcement and penalties depend on the nature of the contravention. Unauthorized lot alterations, failure to register required documents, or contravening conditions imposed by the Committee can trigger municipal enforcement, orders to remedy, registration holds, or court action. Specific monetary penalties and daily fines are not specified on the cited municipal pages; consult the listed official sources for details. Ontario Planning Act[2]
