Payroll is due Friday. Suppliers need to be paid. And the bank just told you the business account is frozen because the owner died. This is one of the more disruptive, least anticipated problems families and business partners face after an Ontario business owner's death — and how quickly it gets resolved depends heavily on how the business was structured and what documentation the estate trustee can produce.

Banks freeze signing authority on death as a matter of standard practice, regardless of how urgently the business needs to keep operating. Understanding why, and what actually reactivates access, can save weeks of avoidable disruption.

Why the Freeze Happens

A bank account is only as good as the legal authority behind whoever is signing on it. When an account holder dies, their personal authority to sign ends immediately — the same way a power of attorney ends automatically on death. The bank generally won't let anyone continue operating the account on the deceased's prior signing authority, because that authority no longer legally exists. Instead, the bank needs to see evidence of who now has legal authority over the business and its accounts, which depends entirely on how the business was structured.

How Structure Changes the Answer

Business structureWhat typically happens on the owner's deathWhat the bank generally needs to see
Sole proprietorshipThe business has no separate legal existence from the owner; the business account is effectively a personal account tied to the deceasedProof of the estate trustee's appointment (generally a Certificate of Appointment of Estate Trustee) before releasing funds or granting signing authority
PartnershipDepends heavily on the partnership agreement — some agreements provide for continuation, others dissolve the partnership on a partner's deathThe partnership agreement, plus estate documentation for the deceased partner's interest
CorporationThe corporation continues to exist as a separate legal entity; the accounts themselves don't disappear, but the deceased's personal signing authority doesCorporate resolutions appointing a new authorized signatory, often alongside evidence of who now controls the deceased's shares

The corporation surviving as a legal entity is a common point of confusion — people assume the business accounts are automatically fine because "the company still exists," but the bank still needs to see who is now authorized to sign, which is a separate question from whether the company continues to exist.

What an Estate Trustee Typically Needs to Do

  1. Notify the bank promptly once appointed (or once the process to become appointed is underway), rather than waiting for a scheduled payment to bounce.
  2. Determine whether probate is actually required for this specific situation — this depends on what the bank and other institutions require, not a one-size-fits-all rule, and is worth confirming early since it affects how quickly things can move.
  3. Gather the right documentation for the business structure involved — the death certificate, the will (if any), the Certificate of Appointment of Estate Trustee once obtained, and, for a corporation, the corporate records showing directorship and share ownership.
  4. For a corporation, arrange for a valid board resolution appointing a new authorized signatory, which requires knowing who currently sits on the board and whether that has changed as a result of the death.
  5. Keep the business's obligations moving where possible — payroll, supplier payments, and lease obligations don't pause just because the account is frozen, so early communication with the bank, employees, and key suppliers about the delay matters.

Common Complications

Why Advance Planning Prevents Most of This

Much of this disruption is avoidable with planning made while the owner is alive: a Continuing Power of Attorney for Property that specifically addresses the business, a shareholders' or partnership agreement with a clear succession mechanism, and keeping corporate records (share registers, director resolutions) current and accessible. A properly funded buy-sell agreement can also address what happens to a deceased owner's interest quickly, rather than leaving it to be sorted out after the fact.

Frequently asked questions

How long does it typically take to unfreeze a business account?

There's no fixed, universal timeline — it depends on the business structure, how quickly the estate trustee is appointed, and how complete the documentation is when presented to the bank. A sole proprietorship generally can't move faster than the estate's own probate timeline allows; a corporation with clear records and a functioning board can sometimes move faster.

Can employees still be paid while the account is frozen?

Not from the frozen account directly. Some businesses arrange bridge financing or use other available funds in the short term, but this needs to be planned for rather than assumed, and should be discussed with the bank and a lawyer as soon as the freeze is identified.

Does a will name a new signing authority for the business bank account?

Not directly — a will typically appoints an estate trustee and may address who inherits business interests, but the bank still needs its own documentation (the Certificate of Appointment, corporate resolutions, etc.) before recognizing anyone's signing authority.

What if the deceased was a co-owner, not the sole owner?

Surviving co-owners generally retain their own signing authority on jointly held accounts, but the deceased's share of the business and any related accounts still need to be dealt with through the estate, particularly if buy-sell or partnership provisions apply.
