Executor Document Checklist Before You Start Notifying Institutions

You don't have to figure this out all at once

Taking on the executor role after losing someone is a lot.

An Ontario executor should gather six categories of documents before contacting any institution. First, proof of death: a death certificate issued by the province or a funeral director's proof of death, required by virtually every organization contacted. Second, executor authority: the will, certificate of appointment as estate trustee, or Letters Probate if granted — financial institutions and government agencies require this before acting on any instruction. Third, personal identification: government-issued photo ID confirming the executor's identity. Fourth, the deceased person's identifying information: full legal name, date of birth, date of death, Social Insurance Number, last known address, and any previous addresses. Fifth, a working account inventory: bank accounts, credit cards, insurance policies, utilities, telecom services, and subscription accounts — ideally with account numbers. Sixth, a correspondence address for confirmations and returned mail. Missing any of these at first contact typically adds at least one to two weeks of delay per institution.

There's grief, there are family dynamics, and somehow, in the middle of all that, there are phone calls to make and forms to fill out.

One thing that genuinely helps: taking a short block of time — before the notifications begin — to pull together your core documents. Not everything. Just the essentials.

Many of the delays executors experience come from starting outreach before the paperwork is organized. You might know roughly which accounts exist, but not the account numbers or the specific details an institution will ask for once you're actually on the phone.

Getting your starting kit in order — proof of death, your authority as executor, your own identification, and a working list of accounts — makes the whole process calmer. You can move through agencies and service providers more steadily, prepare batches of notifications, and keep a clean record without constantly stopping to search for another number or document.

Core documents to gather first

Start with what's most commonly requested. You don't need everything on day one, and that's okay.

If something isn't available yet — like probate or a certificate of appointment — note it in your file. Many institutions will tell you what they'll eventually need. A missing document is a tracked item, not a dead end.

• Death certificate or funeral director's proof of death, depending on the institution's requirements.
• Your identification and contact details as executor.
• The will, estate trustee paperwork, or any authority documents already available.
• Letters probate, certificate of appointment, or court documents if they've been issued.
• Marriage certificate, birth certificate, or beneficiary details if an insurer or pension administrator requests relationship proof.
• The deceased person's full legal name, date of birth, date of death, last address, and any known previous addresses.
• A working inventory of bank accounts, credit cards, utilities, mobile services, insurance, and memberships.
• A mailing address for where confirmations and returned correspondence should go.

Government and benefit information checklist

Government agencies and public benefit programs need accurate identifying information. Having these details ready before you contact Service Canada, the CRA, or ServiceOntario will make those early conversations go more smoothly.

One note worth keeping in mind: don't send original documents unless an institution specifically requires it. Keep copies of everything, and track what you mailed, uploaded, faxed, or emailed.

• Social Insurance Number, if available and appropriate for the agency being contacted.
• CPP, OAS, GIS, or other Service Canada correspondence found in the deceased person's files.
• CRA notices of assessment, tax slips, My Account details, or accountant contact information.
• Health card, driver's licence, photo card, vehicle permit, or accessible parking permit details.
• Passport details if the deceased held a valid Canadian passport.
• Veterans, workplace pension, union, or professional pension correspondence if relevant.

Financial and household account checklist

Financial and household accounts are where most executors end up spending the most time. Some are obvious — like a primary bank account. Others are buried in automatic withdrawals, old statements, online subscriptions, or insurance correspondence that's easy to overlook.

If you can, review at least three months of banking and credit card activity. Six months is better when the estate is complex or when the person managed many accounts on their own.

• Bank accounts, credit cards, lines of credit, mortgages, loans, investment accounts, and credit union accounts.
• Life, home, auto, tenant, travel, health, and group insurance policies.
• Hydro, gas, water, property tax, condo fees, home security, phone, internet, and cable accounts.
• Streaming services, cloud storage, software subscriptions, delivery services, memberships, and loyalty programs.
• Credit bureau notification details and any known fraud protection or credit monitoring services.
• Safe deposit box records, storage unit contracts, vehicle leases, and financing agreements.

Build your notification log before the first call

Your notification log becomes the control centre for this whole process — and it's worth setting up before anything else begins.

It doesn't need to be complicated. A spreadsheet or shared document works well as long as you keep it current. Track institution name, account type, contact details, documents required, date sent, method, tracking number, response received, follow-up date, confirmation date, and any notes. If a lawyer, accountant, or family member needs to understand the file later, a clean log saves everyone real time.

• Record every call, letter, upload, fax, email, and mailed package.
• Save reference numbers, representative names, and case numbers when they're provided.
• Set a follow-up date right away rather than relying on memory.
• Mark items as pending, complete, blocked, or not applicable so the file is easy to scan.
• Keep copies of final confirmations in one folder with a consistent naming convention.

Build a record-keeping habit from the start

As soon as notifications begin, record the date, channel, institution name, and outcome for every action. That sounds simple — but it becomes essential once multiple organizations are in motion at the same time, responses arrive unevenly, and it's hard to remember what happened when.

A clean record also means a lawyer, accountant, or family member can step in if they need to. And it protects you if a beneficiary later asks what was done and when.

The best time to build that habit is before the first notification goes out. Once things are active, it's hard to reconstruct what happened — and easy to lose track of where you are.

When in doubt, save the proof. A postal receipt, fax confirmation, email reply, representative name, or reference number can feel small in the moment. Those details are what make a notification record credible — and they give you something solid to stand behind.
