As of May 2026, Ontario estate files are subject to the “open court principle,” meaning anyone can view a probate file. To secure a Sealing Order for a high-profile or ultra-wealthy estate, you must meet the strict Sherman Estate test, proving that public access poses a serious risk to an important public interest, such as physical safety.
When a person passes away and their estate goes through probate, their Last Will and Testament becomes a public document. For the vast majority of families in cities like Toronto, Oakville, or Kingston, this lack of privacy is merely a mild annoyance. However, for celebrities, ultra-high-net-worth business tycoons, or victims of high-profile tragedies, a public probate file can invite a media circus. Journalists, curious neighbours, and even opportunistic fraudsters can legally pay a small fee at the Superior Court of Justice to read exactly who inherited what, and view the total value of the estate.
Many grieving families ask their estate lawyers to simply “hide” the Will from the public. 🔒 Unfortunately, protecting privacy in Ontario is exceptionally difficult due to the constitutional “open court principle.” A judge will not seal a file just to save a family from embarrassment or to keep their immense wealth a secret. This guide explores the legal hurdles of requesting a Sealing Order, the Supreme Court of Canada’s landmark rules on the matter, and how to protect sensitive estate information.
Step-by-Step Process for Sealing a Probate File in Ontario
Applying for a Sealing Order requires a highly specialized litigation strategy. You must convince a Superior Court judge that the harm of public exposure drastically outweighs the public’s fundamental right to a transparent justice system.
Step 1: Understanding the Sherman Estate Test
Before filing any motions, your law firm must evaluate your case against the Supreme Court of Canada’s 2021 ruling in Sherman Estate v. Donovan. The court ruled that personal privacy and preventing “fishing expeditions” by the media are not good enough reasons to seal a file. You must prove three things: court openness poses a serious risk to an important public interest; the sealing order is necessary to prevent this risk; and the benefits of sealing outweigh the negative effects on free expression.
Step 2: Gathering Evidence of Serious Risk
You cannot simply claim you are afraid of negative media attention. ⚠ You must provide hard evidence of a serious risk. For example, if revealing the addresses of the beneficiaries in the Will would expose them to physical harm, kidnapping, or severe, targeted harassment, this could qualify as a risk to their physical safety (which is an important public interest). Your lawyer will need sworn Affidavits, and possibly police reports or security threat assessments, to back up these claims.
Step 3: Filing the Motion for a Sealing Order
Your estate litigation lawyer will file a Notice of Motion at the Superior Court of Justice, asking the judge to seal the file prior to submitting the actual probate application (the Certificate of Appointment of Estate Trustee). This prevents the documents from hitting the public registry while the judge makes their decision.
Step 4: Arguing for Redactions over Full Sealing
Judges are extremely reluctant to grant blanket Sealing Orders where the entire file is locked away. A more successful strategy is to ask for specific redactions. For instance, your lawyer might argue to leave the Will public but heavily redact the specific names of minor children, their home addresses, and the exact account numbers of offshore corporate trusts. This satisfies the open court principle while mitigating the specific safety risks.
Step 5: Media Intervention at the Hearing
Be prepared for a fight. When a high-profile Sealing Order is requested, major media outlets (like the Toronto Star or the CBC) often hire their own lawyers to intervene and oppose the motion. 📰 The judge will listen to your lawyer argue for safety and privacy, and the media’s lawyers argue for freedom of the press and transparency, before rendering a final decision.
How Much Does it Cost in Ontario?
Fighting for a Sealing Order is a high-level, complex form of litigation that requires significant financial resources. Below are the estimated costs you can expect to incur in Canadian dollars (CAD) as of May 2026.
| Expense | Estimated Cost (CAD) | Details |
|---|---|---|
| Motion Filing Fee | $339 | Standard fee at the Superior Court of Justice. |
| Senior Litigation Lawyer | $600 – $1,200+ per hour | Requires a specialist in constitutional and privacy law. |
| Private Security Risk Assessment | $5,000 – $15,000 | Expert report proving the physical risk to beneficiaries. |
| Total Legal Battle (if opposed) | $25,000 – $75,000+ | If media lawyers intervene and it requires a multi-day hearing. |
How Long Does the Process Take?
Attempting to seal a file significantly delays the actual probate process. Gathering the necessary threat assessments and drafting the motion takes 3 to 6 weeks. Securing a hearing date at the Superior Court, especially if media intervenors are involved, can take 3 to 6 months. During this entire period, the estate remains essentially frozen because you cannot obtain the Certificate of Appointment until the sealing issue is resolved.
Frequently Asked Questions (FAQ)
Can I seal the file just to keep my family’s wealth a secret?
No. The Supreme Court has made it explicitly clear that preserving the confidentiality of financial information or avoiding public embarrassment does not override the open court principle. Wealth alone is not a valid reason for a Sealing Order in Ontario.
Does a Sealing Order hide the Estate Administration Tax (EAT) paid?
If a blanket Sealing Order is granted, the entire file, including the sworn value of the estate and the EAT paid to the Ministry of Finance, is hidden. However, courts usually prefer to leave the total estate value public while redacting specific identifying details.
Are there alternative ways to keep assets private?
Yes. The most effective way to maintain privacy is through pre-death estate planning. Using Multiple Wills (Primary and Secondary Wills) for corporate assets, or transferring wealth into an Alter Ego Trust or Joint Tenancy before death, bypasses the probate process entirely, keeping those assets out of the public court system.
Who can legally view a public probate file?
Literally anyone. Any member of the public, including journalists, distant relatives, or business competitors, can walk into the local courthouse, pay a nominal search fee, and request to read the entire probate file, including the Will.
What happens if the judge denies the Sealing Order?
If the motion is denied, you must make a choice. You can either proceed with the probate application, knowing it will become public record, or you can withdraw the application entirely-though withdrawing means you cannot legally administer the estate’s probatable assets.
