Probate in Ontario: When Is It Required?

Published September 23, 2026 · Meysami Law Professional Corp. · Ottawa

“Probate” is the common name for the Ontario court process used to obtain a Certificate of Appointment of Estate Trustee. The certificate confirms or grants the estate trustee’s authority to administer the estate and identifies the will, if any, on which that authority is based.

Probate is not automatically required for every estate. Whether it is needed depends on the assets, how they are owned, the requirements of banks and other institutions, whether real estate is involved, and whether there is uncertainty about the will or the person authorized to act.

What Does an Estate Certificate Do?

An estate certificate provides formal proof that the court recognizes the applicant as the estate trustee. Financial institutions, the land-registration system, purchasers, and other third parties may request it before allowing the estate trustee to collect, transfer, sell, or distribute estate assets.

If there is a will, the certificate can confirm the authority of the named estate trustee and the will submitted to the court. If there is no will, the court can appoint an estate trustee without a will.

When Might Probate Be Required?

An estate certificate may be needed when:

• A bank or investment institution requires court confirmation before releasing assets
• Real estate must be sold or transferred and the land-registration requirements call for a certificate
• The deceased did not leave a valid will naming an estate trustee
• There are concerns about which document is the final will
• An institution requires protection before relying on the trustee’s authority
• The estate trustee needs formal evidence of authority for litigation or another transaction

Each asset holder may have its own requirements. The value of an account alone does not always determine whether probate is required.

When Might an Estate Be Administered Without Probate?

Some assets may pass outside the estate or may be released without a certificate. Examples can include jointly owned assets with a valid right of survivorship, insurance or registered plans with valid beneficiary designations, or accounts that an institution agrees to release under its internal policy.

These outcomes are fact-specific. Joint ownership and beneficiary designations can raise legal, tax, trust, and family-law questions, so they should not be treated as automatic probate-avoidance tools.

What If There Is No Will?

If a person dies without a will, Ontario’s intestacy rules govern the distribution of the estate. Someone must apply to be appointed as estate trustee if a certificate is required. The order of priority, consents, security requirements, beneficiaries, and application materials may differ from an application based on a will.

Being a relative does not by itself provide immediate authority to access every account or sell estate property.

Ontario’s Small Estate Process

Ontario provides a small-estate probate process for estates valued at up to $150,000. The simplified process uses specific court forms and still requires the applicant to identify the estate assets, beneficiaries, and the basis for the appointment.

The small-estate threshold and process do not mean that every estate under that amount requires probate—or that every asset is included in the value in the same way. The nature of the assets and the institution’s requirements remain important.

Estate Administration Tax

When an estate certificate is requested, Ontario Estate Administration Tax may apply based on the value of the estate reported in the application. Ontario states that no Estate Administration Tax is payable where the estate value is $50,000 or less, although an Estate Information Return may still be required after a certificate is issued.

For estates over that amount, current tax should be calculated using Ontario’s official rules or calculator. Valuation, ownership, real-property encumbrances, and which assets form part of the estate can affect the calculation.

What Should the Estate Trustee Gather?

• The original will and any codicils
• The death certificate or proof of death
• A detailed list of assets, ownership, account information, and date-of-death values
• Information about debts, mortgages, taxes, and other liabilities
• Names and addresses of beneficiaries and people entitled on an intestacy
• Real estate records, corporate records, insurance policies, and beneficiary designations
• Information about prior marriages, dependants, minors, or incapable beneficiaries

Do not distribute the estate before understanding debts, taxes, claims, and the authority required to deal with each asset.

What Happens After the Certificate Is Issued?

The estate trustee may use the certificate to collect and manage estate property. Administration can include protecting assets, maintaining records, paying proper debts and taxes, filing returns, communicating with beneficiaries, keeping accounts, and distributing the estate according to the will or intestacy law.

The certificate is an important step, but it is not the end of estate administration. The trustee continues to have legal responsibilities and should obtain advice where there are disputes, unclear instructions, tax issues, foreign assets, insolvent estates, or dependant-support concerns.
