London Property Valuation - Assessments & Bylaws

Taxation and Finance Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario, property values used for municipal taxation and planning come from a mix of appraisal approaches and the province's assessment process. This guide explains commonly used valuation methods — market (comparables), income, and cost approaches — how the Municipal Property Assessment Corporation (MPAC) produces Current Value Assessments, and how assessments interact with City bylaws and tax billing. The article covers review and appeal routes, typical evidence used by assessors and owners, and practical steps to request reconsideration or appeal an assessment.

Valuation methods explained

Municipal and professional valuations rely on three standard approaches. Understanding their focus helps owners interpret assessment notices and prepare challenges.

  • Market (sales comparison) approach — values a property by comparing recent, similar local sales and adjusting for differences; often central to MPAC assessments. MPAC[1]
  • Income approach — used for rental or commercial properties; capitalizes expected net income to estimate value.
  • Cost approach — estimates replacement cost minus depreciation; common for unique or newer properties.
Different methods carry different weight depending on property type and available data.

How municipal assessments connect to taxes and bylaws

MPAC determines assessed values (Current Value Assessment) which municipalities use to set tax rates; the City of London applies local bylaws and tax policies to billing and enforcement. Assessment affects taxation, development charge calculations, and sometimes eligibility for local relief or exemptions.

Penalties & Enforcement

Enforcement of bylaws and tax collection involves separate authorities and procedures. Specific monetary fines or tax-penalty rates applicable to assessments, property standards, or late tax payments are documented by the enforcing office; where amounts or schedules are not listed on the cited official page they are noted below as not specified on the cited page.

  • Fine amounts: not specified on the cited page.[2]
  • Escalation: first, repeat, or continuing offence ranges — not specified on the cited page.[2]
  • Non-monetary sanctions: orders to comply, property standards orders, court charges, or remediation orders issued by the City or provincial tribunals.
  • Enforcer and contact: By-law Enforcement and Municipal Taxation offices handle complaints and enforcement; see the City of London enforcement contact page for reporting procedures and contacts. City of London By-law Enforcement[2]
  • Appeal routes: assessment appeals are filed with the Assessment Review Board (part of Tribunals Ontario); exact filing timelines and forms are given by the tribunal. Assessment Review Board[3]
If you receive an order or notice, act quickly and record all correspondence.

Applications & Forms

Common forms and filings:

  • MPAC Request for Reconsideration (RFR) — for asking MPAC to review an assessment; form details and submission methods are on MPAC's site.[1]
  • Assessment Review Board appeal forms — for formal appeals after review; see the tribunal site for filing procedures and deadlines.[3]
  • City tax payment or penalty forms — where published by the City; fees and exact submission steps are provided by the relevant City office or webpage.[2]
Some reviews require local evidence like comparable sales, leases, or income statements.

How to prepare evidence for valuation reviews

  • Collect recent comparable sales, listing and closing dates, and adjustment notes.
  • For income properties, prepare rent rolls, expense statements, and vacancy assumptions.
  • Document renovations, depreciation, or unique site constraints with permits, invoices, and photos.
