Appraiser Costs vs Real Estate Agent Opinions of Value for Ontario Probate

13 Jun 2026 5 min read No comments Probate & Trust Administration Ontario
🔍

When filing for probate in Ontario, you must declare the home’s value on the exact date of death to calculate the Estate Administration Tax (EAT). While a free realtor’s “Letter of Opinion” is acceptable for simple estates, hiring a certified appraiser (costing roughly $400 to $800 CAD) provides superior legal protection if the Ministry of Finance audits the estate.

When a homeowner passes away in Ontario, their real estate is usually the most valuable asset in their estate. To legally transfer or sell the property, the executor must generally apply for a Certificate of Appointment of Estate Trustee (probate). A mandatory part of this process involves declaring the exact “fair market value” of the home on the specific day the person died. This number directly dictates how much Estate Administration Tax (EAT) the estate must pay to the provincial government.

Executors in cities like Toronto, Hamilton, and Vaughan face a crucial decision: should they use a free Letter of Opinion from a local real estate agent, or should they pay out of pocket for a formal, certified appraisal? Getting this number wrong can lead to massive tax penalties and aggressive audits by the Ontario Ministry of Finance. In this legal guide, we will compare both options to help you protect the estate and your personal liability as an executor. 📍

Step-by-Step Process in Ontario

Determining the property’s date-of-death value is a strict legal requirement. The value is not what the house sells for six months later; it is strictly what it was worth on the exact day of passing. Generally, an experienced probate lawyer will strongly advise you on which valuation method is safest for your specific situation.

Step 1: Understand the EAT Calculation

Before choosing a valuation method, understand why accuracy matters. In Ontario, the Estate Administration Tax is calculated at $15 for every $1,000 of estate value above $50,000. 💵

If you undervalue a $1.5 million Toronto home by $200,000 to “save on taxes,” you are committing tax fraud. If the Ministry of Finance audits the estate, they will reassess the value, charge you the missing tax, and potentially levy severe financial penalties against you personally as the executor.

Step 2: Option A – The Realtor’s Letter of Opinion

Many executors ask a local real estate agent for a Letter of Opinion of Value. The agent will look at recent comparable sales (comps) in the neighbourhood and provide a short letter estimating the home’s worth.

Pros: It is usually completely free, and it is fast.
Cons: A realtor is a salesperson, not a certified valuer. Their letters lack deep methodology and are frequently rejected by government auditors during complex estate audits, leaving the executor vulnerable.

Step 3: Option B – The Certified Appraisal

The safer legal route is hiring an appraiser certified by the Appraisal Institute of Canada (AIC). They will physically inspect the property, document its condition on the date of death, and produce a massive, 20+ page legally defensible report. 📄

Pros: It provides bulletproof protection during an audit. The Ministry of Finance rarely challenges a formal AIC appraisal. It is highly recommended if the home is unique, in poor condition, or if beneficiaries are aggressively fighting over the estate’s value.
Cons: It costs the estate money upfront.

Step 4: File the Estate Information Return (EIR)

Once you receive your probate certificate from the Superior Court, you have exactly 90 days to file the Estate Information Return (EIR) with the Ministry of Finance.

This mandatory document breaks down exactly how you arrived at the estate’s total value. Having a certified appraisal securely attached to your files ensures that when you sign this government document, you are acting with utmost diligence.

How Much Does it Cost in Ontario?

Executors are often hesitant to spend estate money, but investing in an appraisal is essentially buying an insurance policy against future government tax audits. 💰

  • Realtor’s Letter of Opinion: Usually $0 CAD. Agents provide these for free, hoping you will hire them to eventually list the property.
  • Certified AIC Appraisal: Typically ranges between $400 and $800 CAD for a standard residential home, depending on the municipality and the complexity of the property.
  • Capital Gains Tax (CRA): Accurate valuation also establishes the “cost base” for the beneficiaries. If the house increases in value between the date of death and the date it is finally sold, the estate owes federal capital gains tax on that specific difference.
Valuation MethodCost to Estate (CAD)Protection During a Tax Audit
Property Tax Bill (MPAC)$0Very Low (Almost always rejected)
Realtor Letter of Opinion$0Medium (Acceptable for simple estates)
Certified AIC Appraisal$400 – $800Highest (Legally defensible)

How Long Does the Process Take?

Obtaining a Letter of Opinion from a realtor can usually be accomplished in just 2 to 4 days.

Hiring a certified appraiser takes slightly longer. You must schedule the physical walk-through, and then wait for the appraiser to draft their comprehensive report. This entire process generally takes 1 to 3 weeks. Ensure you request the appraisal early so it does not delay your probate court application.

Frequently Asked Questions (FAQ)

Can I just use the value on the MPAC property tax bill?

No, you absolutely should not. The Municipal Property Assessment Corporation (MPAC) assesses homes for property tax purposes, and their values are notoriously outdated, often trailing true market value by several years. The Ministry of Finance expects current fair market value, and relying on MPAC is a massive red flag for an audit.

What if the house sells for much more than the appraisal a few months later?

If the real estate market is hot and the house sells for $100,000 more than the date-of-death appraisal just three months later, you do not have to amend your probate tax (EAT). However, the estate will owe the CRA capital gains tax on that $100,000 increase in value during the estate’s final tax return.

Who pays for the certified appraiser?

The cost of the appraisal is considered a legitimate “expense of administration.” This means the executor pays the appraiser using the deceased’s funds from the estate account. You do not have to pay for this out of your own personal pocket.

Do I need an appraisal if the house is going directly to a surviving spouse?

If the house was owned as “Joint Tenants with Right of Survivorship,” the property legally bypasses the estate entirely and transfers directly to the surviving spouse. Because it bypasses the estate, it is not subject to probate tax, and an appraisal for probate purposes is completely unnecessary.
