In Ontario, these terms mean the same thing.

"Executor" is the term most people are familiar with — it's the person named in a will to carry out your wishes after you die.

"Estate trustee" is the official legal term used in Ontario law.

So if your will says "executor" or if a lawyer refers to your "estate trustee," they're talking about the same role and the same person.

This is one of the most common points of confusion, and it matters a lot.

A Power of Attorney (POA) only has authority while you are alive. If you become incapable of managing your own affairs — due to illness, injury, or cognitive decline — your Power of Attorney can step in and act on your behalf, including for your business.

The moment you pass away, your Power of Attorney's authority ends completely.

From that point forward, only your executor (estate trustee) has legal authority to manage your estate, including your business.

You need both roles covered, and they are often — but not always — the same person.

Not automatically — and this is one of the most important things business owners don't realize.

If your spouse works in your business but their name isn't on the corporation, the business bank account, or your registration documents, they have no legal authority over the business just because they're your spouse or because they've been doing the work.

If you become incapacitated, they would need a valid Power of Attorney naming them specifically.

If you pass away, they would need to be appointed as your estate trustee — which, if you have no will, requires a court application, even though they may have been running the books and supporting your operations for years.

Being involved in a business and having legal authority over it are two very different things in the eyes of Ontario law.

A personal will can cover your business if it's written properly and specifically addresses your business interests — but most personal wills don't.

Many people write a will before they start a business, or write a general will that talks about "all my assets" without addressing what should specifically happen to the business, who should run it temporarily, or how shares and ownership should transfer.

Some business owners — particularly those who are incorporated — choose to create a secondary or "dual" will that deals specifically with their business and corporate assets, in addition to their primary personal will.

Whether you need a separate document depends on your structure and your goals — this is exactly the kind of question to bring to an Ontario estate lawyer.

A "what if I die" plan is a practical, organized document — not a legal one — that brings together everything your family or estate trustee would need if something happened to you.

It includes your business operations, your account details and credentials, your key contacts, your legal documents' locations, and your personal wishes.

It complements your will and your Powers of Attorney rather than replacing them.

Some people find the traditional language of "estate planning" or "succession planning" abstract and easy to put off.

Calling it a "what if I die" plan tends to make the urgency — and the relief of finally doing it — much more real.

Start small.

You don't need to document everything at once.

Begin by writing down the three to five things that absolutely cannot be missed if you were suddenly unavailable for a week — recurring bills, client check-ins, critical deadlines.

Then, identify who would need to know your business bank account and CRA My Business Account details.

From there, build outward: your key documents, your client list, your legal paperwork.

A guided framework — like a preparedness consultation or a structured workbook — can help you avoid missing the most critical pieces, but the most important step is simply starting.
