  • Filing Articles of Dissolution with the Ontario Business Registry (a $25 filing fee, as of mid-2026 — verify the current fee before relying on it) legally ends the corporation's existence.

Filing Articles of Dissolution feels like the finish line, and legally, it mostly is — but a surprising amount of practical cleanup still needs to happen afterward. A dissolved corporation can still leave behind an open bank account, an active CRA payroll account, or unremitted obligations that create headaches for the very people who thought they were done.

This article walks through the practical wind-down steps after dissolving an Ontario corporation, in the order they generally need to happen.

Dissolution Is a Legal Event, Not a Full Wind-Down

Filing Articles of Dissolution with the Ontario Business Registry (a $25 filing fee, as of mid-2026 — verify the current fee before relying on it) legally ends the corporation's existence. But the paperwork to actually unwind the business's affairs — accounts, tax registrations, remaining assets — is a separate, practical process that a director or officer still needs to complete.

Importantly, debts should be settled and remaining assets distributed before you file for dissolution, not after. Dissolving a corporation that still owes money or holds unclaimed assets creates unnecessary complications, and does not make those obligations disappear.

Step-by-Step Wind-Down Checklist

  1. Settle outstanding debts and distribute remaining assets before filing Articles of Dissolution, following the corporation's normal decision-making process for a voluntary wind-up.
  2. Ensure all payroll source deductions and HST have been remitted. This step matters even more than it might seem: certain unremitted amounts can create personal liability for a director, and dissolving the corporation does not erase that exposure.
  3. File Articles of Dissolution through the Ontario Business Registry.
  4. Close relevant CRA program accounts — payroll, GST/HST, and corporate income tax — associated with the corporation's business number, following CRA's current process for a dissolved corporation.
  5. Close the corporate bank account(s). Most banks will ask for proof of dissolution before closing a corporate account, so keep the confirmation of dissolution from the Ontario Business Registry on hand.
  6. Notify other stakeholders — the corporation's insurer, landlord (if any lease is still active), key suppliers, and any licensing or regulatory bodies the corporation dealt with.
  7. Retain the corporation's records for a period afterward. How long you should keep financial and tax records after dissolution depends on current CRA guidance and any other applicable retention obligations — confirm the current recommendation with your accountant rather than assuming a fixed number of years.

Common Pitfalls After Dissolution

Who to Notify: A Quick Reference

StakeholderWhy It Matters
CRA (payroll, GST/HST, corporate tax accounts)Program accounts tied to the business number need to be formally closed
Bank(s)Accounts need to be actively closed; most require proof of dissolution
InsurerCancel or confirm the status of any business insurance policies
LandlordAny active lease needs to be resolved separately from the corporate dissolution itself
Licensing or regulatory bodiesIndustry-specific licences or permits usually need their own closure process

Frequently asked questions

Can we close the bank account before filing Articles of Dissolution?

Generally, yes — and it can make sense to close accounts once all funds have been properly distributed and no further transactions are expected, rather than leaving an account open with no activity. Just make sure every outstanding obligation has actually been settled first.

What if we discover an unremitted HST amount after the corporation is already dissolved?

This does not simply disappear because the corporation no longer exists. Depending on the amount and circumstances, a director may still have personal exposure for unremitted source deductions or HST — speak with an accountant or lawyer promptly rather than assuming dissolution resolved it.

Do we need to keep paper records, or is a digital copy enough?

Properly maintained digital copies are generally acceptable in principle, but confirm the current record-keeping expectations for your specific tax and corporate obligations before discarding originals.

What happens if we find an asset (like an old bank balance) after dissolution?

An asset discovered after a corporation has been dissolved can raise its own legal questions about who is entitled to claim it. This is a situation to get specific legal advice on rather than assuming any particular default outcome.
