Key takeaways
  • Ontario's probate guidance does not require a formal appraisal; the application asks for the estate value as at the date of death.
  • If you cannot fix the exact value yet, a sworn estimate may be used, followed by a sworn statement of the real value within six months.
  • Tax on a mortgaged Ontario home is based on equity, meaning value less the registered mortgage or lien.
  • Whatever figure you use, you swear to it, so keep a record of how you arrived at it.

You have been named executor, there is a house in the estate, and the probate application asks for its value. Many people assume that means paying for a formal appraisal. Others wonder whether a realtor's opinion or a property tax assessment will do.

This article explains what the application actually asks for, what Ontario's guidance says about appraisals, which assets count toward the total, and how a sensible valuation protects you. It is general information, not advice on your particular estate.

What the probate application asks you to report

The application for a certificate (Form 74A) asks for the total value of real property, the total value of personal property and the total estate value. The value is measured as at the date of death, not the date you apply or the date you eventually sell.

The estate's value is stated in Canadian dollars at the date of death. Estate administration tax is paid as a deposit when you apply and becomes the tax once the certificate is issued.

Is a formal appraisal required?

Ontario's guidance on applying for probate does not require a formal appraisal. It describes the estate value as at the date of death and allows a sworn estimate to be used, with a later sworn statement of the actual value.

That does not mean any number will do. You are swearing or affirming the value, so it should be an honest, reasonable figure you can explain. Whether a realtor's opinion, a written appraisal or another source of information is the sensible choice depends on the property, the size of the estate and how contested the value might be. A lawyer can help you decide what fits your situation.

What counts toward the estate value

The house is only part of the picture. The total includes many other assets, and some things are left out. The table below summarizes the main items.

ItemTreatment
Ontario real estateCounted, less registered encumbrances such as a mortgage or lien
Bank accounts, including foreign banksCounted
InvestmentsCounted
RRSPs, RRIFs and TFSAs with no beneficiary designationCounted
Vehicles and vessels wherever locatedCounted
Real estate outside OntarioExcluded on a full estate certificate
Jointly held assets that pass to the surviving ownerExcluded
Registered plans and insurance with a named beneficiaryExcluded
Funeral expenses, lawyer's fees, credit card debt, vehicle debt, real estate commissions, unregistered loansCannot be deducted

How the number affects the tax

For applications made on or after January 1, 2020, the tax is $15 for every $1,000 of estate value, or part of $1,000, with the first $50,000 exempt. The value is rounded up to the next thousand dollars before the rate is applied. For example, a $500,000 estate owes (500 − 50) × $15, which is $6,750.

If the estate is valued at $50,000 or less, no tax is payable, but you must still apply for the certificate and file the Estate Information Return. The older two-band system with a $5-per-$1,000 band applied only to applications made before 2020 and no longer applies.

Because the mortgage reduces the value of the home for this purpose, tax on a mortgaged Ontario home is based on the equity, not the full market value. Real estate commissions you expect to pay on a sale cannot be subtracted.

If you cannot pin down the value yet

In some cases the tax can be paid on an estimated value that is sworn or affirmed on the application. You then undertake to file a sworn statement of the total value within six months and pay any balance owing. If you cannot pay the tax when applying, you can ask a judge for an order allowing payment later once estate assets are accessible.

If you used an estimate, you will later need to give an amended Estate Information Return within 60 days of the actual value being shared with the court.

What to do next

Frequently asked questions

Is a realtor's opinion enough for probate?

Ontario's guidance does not require a formal appraisal and describes the value as at the date of death, sworn by you. Whether a realtor's opinion is enough support depends on the property and the circumstances, so it is worth confirming with a lawyer.

Do I deduct the mortgage from the house value?

Yes, registered encumbrances such as a mortgage or lien can be deducted from the value of Ontario real estate, so the tax is based on equity. Unregistered loans and lines of credit cannot be deducted.

What if I get the value wrong?

If you used an estimate, you must file a sworn statement of the actual value within six months and pay any balance. Incorrect or incomplete information requires an amended Estate Information Return within 60 days of becoming aware of the problem.

Does a house outside Ontario count?

Real estate outside Ontario is excluded from the estate value for tax purposes on a full estate certificate, although foreign bank accounts and vehicles are still counted.
