Running a business takes courage, and so does knowing when it’s time to close one. Whether your company has run its course, you’re retiring, or the numbers just aren’t adding up anymore, dissolving a corporation in Ontario is a process that must be done properly or it can come back to haunt you.
This guide breaks down exactly what dissolving an Ontario corporation means, the types of dissolution you should know about, what needs to happen before you file anything, and the step-by-step process to close your incorporated business cleanly and legally.
What Does It Mean to Dissolve a Corporation in Ontario?
Think of your corporation as a separate “legal person.” When you incorporated, you created an entity that could own property, sign contracts, hire employees, and carry on business- all in its own name. Dissolving that corporation is the legal process of ending its existence as that separate “person.”
Once dissolved, your corporation can no longer own property, carry on business, or enter into any contracts. It simply ceases to exist in the eyes of the law.
This is governed primarily by the Ontario Business Corporations Act, R.S.O. 1990, c. B.16 (the “OBCA”), which sets out the rules, requirements, and consequences of dissolution for Ontario-incorporated businesses.
The first thing to be aware of is that dissolution does not mean shutting down operations. You can unsubscribe from everything and turn away clients, but your business will remain legally in existence until it is formally dissolved. As long as your company continues to exist, there are various responsibilities that come with it.
Illustration: Imagine you’ve been renting an apartment under a lease. Just because you’ve moved out doesn’t mean you’ve ended the lease. You still owe rent until you formally terminate it. Dissolution is like formally terminating your corporation’s “lease” on legal existence.
Types of Corporate Dissolution in Ontario
Not all dissolutions are the same. There are two main ways a corporation in Ontario can be dissolved: voluntarily or involuntarily.
Voluntary Dissolution
This is when the corporation itself- through its directors and shareholders decides to dissolve. You are in control of the process, the timing, and the steps involved.
Voluntary dissolution is almost always the preferred route. It lets you wrap things up on your own terms, settle all debts in an orderly fashion, and distribute any remaining assets to shareholders before the corporation ceases to exist.
Under Section 237 of the OBCA, a corporation may be dissolved with the authorization of:
- A special resolution passed at a properly called shareholders’ meeting (usually requiring at least a two-thirds majority of votes), or
- The written consent of all shareholders entitled to vote, or
- All incorporators (or their personal representatives), if the corporation never commenced business and never issued shares.
Involuntary Dissolution (Cancellation by the Government)
This happens when the government dissolves your corporation without your consent usually because you’ve failed to comply with legal requirements.
Under the OBCA, the Director appointed to administer the Act may order dissolution if “sufficient cause” is shown. Common grounds include failure to file annual returns, failure to maintain the minimum number of resident Canadian directors, failure to file financial statements (for public companies), or failure to file tax returns.
The Ontario government typically sends a notice to the corporation or publishes its intent in The Ontario Gazette giving the corporation 90 days to fix the problem. If nothing is done, the Director may cancel the corporation’s certificate of incorporation, effectively dissolving it involuntarily.
Involuntary dissolution will not release you from any liabilities or tax responsibilities. In fact, under Section 242 to 244 of the OBCA and the Forfeited Corporate Property Act, 2015, a corporation can be sued as if it was not dissolved. All property that is left after the dissolution can become property of the Crown.
Court-Ordered Dissolution
A court can also order the dissolution of a corporation in certain circumstances – for example, where shareholders are deadlocked and cannot manage the company, or where it is just and equitable to wind up the business. This is a less common route and typically involves litigation.
Before You Dissolve Your Ontario Corporation
Before you file a single document with the Ontario Business Registry, there is significant groundwork to complete. Skipping these steps can expose directors and shareholders to serious personal liability.
1. Stop Operations and Wrap Up Business
The first practical step is to actually stop doing business. Complete any outstanding client work, send your final invoices, and collect any accounts receivable. Cancel leases, software subscriptions, supplier agreements, and any other ongoing commitments.
As the Avalon Accounting guide notes, once you cease operations, your corporation essentially becomes a holding company, it holds some assets and liabilities but is no longer actively trading. This is the moment to consult your accountant and lawyer.
2. Take Care of Your Employees
If your corporation has employees, you have legal obligations to meet before dissolving. This includes proper notice of termination or pay in lieu of notice under the Employment Standards Act, 2000, ensuring all wages and vacation pay are fully paid out, filing Records of Employment (ROEs) with Service Canada so employees can claim Employment Insurance benefits, and remitting all payroll source deductions (income tax, CPP, EI) to the Canada Revenue Agency (CRA).
Directors’ personal liability for employees is real. Under the OBCA and the Income Tax Act, directors can be held jointly and severally liable for up to six months of unpaid wages and up to twelve months of unpaid vacation pay. Directors can also be personally liable for unremitted payroll source deductions (income tax, CPP, EI) and for unremitted HST collected from customers.
Case Law: Director Liability: In Priftis v. The Queen, 2012 TCC 414 (CanLII), the Tax Court of Canada considered whether dissolution of a corporation started the two-year limitation clock for CRA to pursue a director personally for the corporation’s unremitted tax debts. The case illustrates how closely CRA monitors directors’ obligations even after a corporation is dissolved and why properly resigning as director and filing a Notice of Change with the Ministry is critical before dissolution.
3. Settle All Debts and Liabilities
A corporation cannot be voluntarily dissolved if it still has outstanding debts or unresolved liabilities. The law is clear: debts must be paid, or provisions must be made for them, before dissolution.
This means paying all outstanding supplier invoices, settling any loans (including shareholder loans), resolving any legal claims or disputes, and dealing with any known or unknown creditors. If there are creditors whose claims are uncertain, you may need your lawyer to draft a formal mechanism (sometimes called a “general conveyance”) to address those contingent claims.
4. File Outstanding Tax Returns and Close CRA Accounts
This is where your accountant earns their fee. You will likely need to file at least two final corporate tax returns: one for the last full year of operations, and one up to the date of dissolution. Ideally, the dissolution-date return should show a nil balance, an empty shell.
- HST/GST Account (RT)
All outstanding HST/GST returns must be filed up to the date you stopped collecting HST from customers. Pay any balance owing, collect any refunds, and then apply to close your RT account with CRA. You can close your HST account before you formally dissolve the corporation- in fact, this is recommended.
- Payroll Account (RP)
After completing your final payroll, file final T4s for all employees, ensure all remittances are paid or refunded, and apply to close your RP (payroll) account. Don’t forget the ROEs for Service Canada.
- Corporate Tax Account (RC)
CRA will automatically close your corporate tax (RC) account once it receives your notice of dissolution and your final tax return.
- T5 Statements (RZ)
If you distribute assets or dividends to shareholders as part of winding up, T5 Statements of Investment Income must be filed. CRA will automatically close your RZ account once your final corporate return and notice of dissolution are received.
5. Get the Corporate Minute Book Up to Date
Whether your corporation is provincially (OBCA) or federally (CBCA) incorporated, the corporate minute book must be current before dissolution can proceed. This means all annual returns must have been filed, director and officer information must be accurate, and any shareholder or director resolutions must be signed and in order.
A disorganized minute book is one of the most common reasons dissolutions gets delayed or causes problems down the line.
6. Distribute Remaining Assets to Shareholders
Once all debts are paid and all CRA accounts are closed or in the process of closing, whatever assets remain- cash, equipment, investments must be distributed to shareholders in accordance with their entitlements before or at the time of dissolution.
The calculation of how much each shareholder receives, and the tax consequences of that distribution (including whether it triggers capital gains or dividend income), depends on your specific situation. This is why tax planning with your accountant is essential especially if the corporation has significant retained earnings.
If the corporation has accumulated significant retained earnings, distributing them all at once as a dividend can result in a large personal tax bill for shareholders. Depending on circumstances, it may be more tax-efficient to take distributions over time. Talk to your accountant before triggering dissolution.
Step-by-Step Process to Dissolve a Corporation in Ontario
Once all the pre-dissolution groundwork is done, here is the formal process under the OBCA.
Step 1: Pass the Required Authorization
For a corporation that has issued shares (i.e., most active businesses), you need formal shareholder authorization for dissolution. This is typically done in one of two ways:
Option A- Shareholder Meeting:
Hold a properly called shareholders’ meeting at which dissolution is specifically identified as a purpose. A special resolution is passed meaning at least two-thirds of the votes cast by shareholders entitled to vote, unless the articles of the corporation set a different threshold (which cannot be less than 50% of all votes of shareholders entitled to vote).
Option B- Written Consent:
All shareholders entitled to vote sign a written resolution consenting to the dissolution. For small private corporations with one or a handful of shareholders, this is the simpler and more common route.
For a corporation that has never commenced business and never issued shares, the incorporators (or their personal representatives) may authorize dissolution directly.
Director Resolution:
In addition to shareholder authorization, the board of directors should pass a resolution confirming the decision to dissolve, authorizing the necessary filings, and dealing with matters such as asset distribution and debt settlement.
All resolutions must be kept in the corporate minute book.
Step 2: Confirm No Outstanding Debts, Liabilities, or Assets
Before filing, confirm in writing (through your resolutions) that:
- All debts and obligations have been paid or adequately provided for,
- There are no legal proceedings pending against the corporation,
- Any remaining assets have been distributed to shareholders or dealt with appropriately, and
- No property of the corporation has been distributed that was needed to satisfy obligations.
If your corporation has property that cannot be easily distributed, speak to a lawyer about how to handle it.
Step 3: Obtain Ontario Ministry of Finance Consent
For Ontario corporations, when Articles of Dissolution are submitted to the Ministry of Government and Consumer Services, a request is automatically sent to the Ontario Ministry of Finance to obtain its consent to the dissolution. This consent is typically only granted once the Ministry of Finance is satisfied that all provincial tax obligations have been met and any outstanding returns have been filed.
This step can add time to the process sometimes several weeks- so make sure all provincial tax filings are current before you submit the Articles.
Step 4: Prepare and File the Articles of Dissolution
The core dissolution document is the Articles of Dissolution, filed through the Ontario Business Registry (OBR) online portal at ontario.ca/businessregistry.
The Articles of Dissolution must confirm:
- The name of the corporation,
- That dissolution was duly authorized under Section 237(a) or (b) of the OBCA,
- That the corporation has no debts, obligations, or liabilities, or that they have been duly provided for,
- That after satisfying all liabilities, remaining property has been distributed to shareholders or dealt with in accordance with the OBCA, and
- That there are no legal proceedings pending against the corporation.
The current filing fee is payable online through the OBR portal (fees are subject to change; confirm the current fee at ontario.ca/businessregistry before filing).
Step 5: Receive the Certificate of Dissolution
Once the Ministry reviews and approves the Articles of Dissolution and once Ontario Ministry of Finance consent has been obtained- the government issues a Certificate of Dissolution. This is the official document confirming that your corporation no longer legally exists.
Keep the Certificate of Dissolution in your corporate minute book. It is the definitive proof that the corporation was properly wound up.
Step 6: Update the Corporate Minute Book and Close Corporate Accounts
After receiving the Certificate of Dissolution:
- Update the corporate minute book to reflect the dissolution and file the Certificate.
- Close your corporate bank account (make sure you’ve received all final deposits and cleared any outstanding cheques first).
- Notify your insurance provider, cancel business licences, and update any relevant registrations.
- Keep all corporate records for at least six years after dissolution- CRA can still audit, and legal claims can still arise.
Even after dissolution, a civil, criminal, or administrative action or proceeding may be brought against a dissolved corporation as if it had never been dissolved. Under sections 242–244 of the OBCA and the Forfeited Corporate Property Act, 2015, parties commencing actions must serve the Public Guardian and Trustee and the relevant Minister. This is why proper pre-dissolution cleanup is so critical- you want no loose ends.
Federal vs. Provincial Corporation: Does It Matter?
Yes, it matters significantly.
If your corporation was incorporated federally under the Canada Business Corporations Act (CBCA), the process is similar in concept but goes through Corporations Canada, not the Ontario Ministry. You would file Articles of Dissolution with the federal government and deal with CRA for federal obligations.
CBCA vs OBCA – Corporate Dissolution Comparison
| Category | CBCA – Federal Corporation | OBCA – Ontario Corporation |
| Who can dissolve | Shareholders (by special resolution), or all incorporators if no shares issued and business not commenced. Directors cannot dissolve unilaterally (s. 211 CBCA). | Shareholders by special resolution or written consent of all shareholders entitled to vote, or all incorporators if no shares issued and business not commenced (s. 237 OBCA). |
| Shareholder vote threshold | Special resolution = at least 2/3 (66.67%) of votes cast, or written consent of all shareholders entitled to vote (s. 211 CBCA). | Special resolution = at least 2/3 of votes cast, OR a lower threshold in the articles – but never less than 50% of all votes of shareholders entitled to vote (s. 237(a) OBCA). |
| Governing regulator & filing portal | Regulator: Corporations Canada
Portal: corporationscanada.ic.gc.ca |
Regulator: Ontario Ministry of Government and Consumer Services (MGCS)
Portal: Ontario Business Registry (OBR) – ontario.ca/businessregistry |
| Articles of Dissolution form | Form 17 – Articles of Dissolution (CBCA). Filed electronically through Corporations Canada’s online portal. | Ontario Articles of Dissolution form filed through the OBR portal. Submitted digitally; no separate form number. |
| Tax clearance requirement | CRA consent required. Corporations Canada will not issue a Certificate of Dissolution until CRA confirms all federal tax obligations are met (s. 211(5) CBCA). | Ontario Ministry of Finance (MOF) consent required. When Articles are filed, a request is automatically sent to the MOF. Consent granted only when provincial tax obligations are satisfied. CRA also involved for federal obligations. |
| Pre-dissolution conditions | (1) Pay or adequately provide for all debts/liabilities; (2) distribute remaining property to shareholders per their entitlements; (3) no pending legal proceedings; (4) all annual returns filed with Corporations Canada (s. 211 CBCA). | Same substantive conditions: pay all debts, distribute assets, no pending legal proceedings, all annual returns current with the OBR, minute book up to date. |
| Register of individuals with significant control (ISC) | REQUIRED – CBCA corporations must maintain and file ISC information. Must be current before dissolution. This is a CBCA-specific compliance step. | NOT REQUIRED – OBCA corporations do not have a federal ISC filing obligation (though Ontario has its own provincial beneficial ownership rules). |
| Involuntary dissolution grounds | Corporations Canada may dissolve for: failure to file annual returns, failure to comply with CBCA requirements, or court order. Notice given before action. | OBCA Director may dissolve for: failure to file annual returns, insufficient resident Canadian directors (<25%), failure to comply with OBCA requirements, or court order. Notice published in The Ontario Gazette with 90-day cure period (ss. 240–241 OBCA). |
| Resident Canadian director requirement | At least 25% of directors must be resident Canadians (s. 105 CBCA). For boards fewer than 4 directors, at least 1 must be a resident Canadian. Failure is a ground for involuntary dissolution. | Same 25% resident Canadian director requirement under the OBCA. Failure to maintain this threshold is an explicit ground for involuntary dissolution by the OBCA Director. |
| Post-dissolution legal actions | Actions may be brought against or by a dissolved corporation as if it had not been dissolved (s. 226 CBCA). Undistributed property vests in the Crown; Crown may be served in place of the corporation. | Civil, criminal, or administrative proceedings may be commenced against a dissolved OBCA corporation as if it had not been dissolved (s. 242 OBCA). Property vests in the Crown under the Forfeited Corporate Property Act, 2015. Public Guardian and Trustee must be served. |
| Revival after dissolution | Dissolved CBCA corporation may be revived by application to Corporations Canada. On revival, deemed never to have been dissolved – all rights and liabilities restored (s. 209 CBCA). | Dissolved OBCA corporation may be revived by application to the OBCA Director. Same effect: restored to prior legal position as if never dissolved, including all liabilities. |
| Director personal liability for tax | Directors personally liable for unremitted payroll deductions (CPP, EI, income tax) and HST under the Income Tax Act (s. 227.1) and Excise Tax Act. CRA has 2 years from date of dissolution to assess. | Same personal liability for unremitted payroll deductions and HST. ITA s. 227.1 applies equally. See: Priftis v. The Queen, 2012 TCC 414 (CanLII) – dissolution date starts the 2-year CRA assessment clock for directors. |
| Director liability for employee wages | Directors jointly and severally liable for up to 6 months’ unpaid wages and 12 months’ vacation pay. Claim must be proved within 6 months of commencement of dissolution or date of dissolution (s. 119 CBCA). | Same 6 months’ wages / 12 months’ vacation pay liability. The OBCA does not contain the same 6-month claim limitation as the CBCA – claims against directors may be brought within a longer window under other applicable statutes. |
| CRA accounts to close | HST/GST (RT), Payroll (RP) – close proactively. Corporate Tax (RC) and T5 (RZ) – closed automatically by CRA on receipt of notice of dissolution and final returns. | Identical CRA account closure process: RT, RP, RC, RZ. Note: Ontario MOF tax clearance is an additional provincial step unique to OBCA corporations. |
| Certificate issued on dissolution | Certificate of Dissolution issued by Corporations Canada. This is the definitive proof of federal dissolution. | Certificate of Dissolution issued by the Ontario Ministry of Government and Consumer Services through the OBR. |
| Key practical difference | ISC Register: Must maintain and file register of individuals with significant control – an extra compliance layer before dissolution that OBCA corporations do not face at the federal level. | Provincial tax clearance: The automatic Ontario MOF consent request is unique to OBCA. This adds processing time that purely federal CBCA corporations do not encounter. |
What Happens If You Don’t Dissolve Properly?
Ignoring dissolution or doing it incorrectly can have serious consequences:
- Ongoing filing obligations. A corporation that is not dissolved must continue filing annual returns and corporate tax returns, even if it is dormant. Failure to do so triggers involuntary dissolution and can lead to the corporation’s property vesting in the Crown.
- Director personal liability. As discussed above, directors can be personally assessed by CRA for unremitted HST, payroll source deductions, and other corporate tax obligations even after the corporation is dissolved- if proper steps were not taken.
- Assets forfeited to the Crown. Any property belonging to a dissolved corporation that was not properly distributed before dissolution may vest in the Crown under the Forfeited Corporate Property Act, 2015. Reclaiming those assets can be complicated and expensive.
- Difficulty reviving. If a corporation is involuntarily dissolved and you later want to revive it, the process (known as “revival”) requires bringing the corporation back to full legal standing- filing all outstanding returns, paying all fees and penalties, and meeting current compliance requirements. A voluntary, orderly dissolution avoids this headache entirely.
Illustration: Suppose a small Ontario corporation stopped operating in 2022 but never formally dissolved. By 2026, CRA has assessed the director personally for unremitted HST from those final months of operation, and the Ministry has involuntarily dissolved the corporation for failing to file annual returns. The director now faces a personal tax debt and needs to pay a lawyer to sort out the mess- all of which could have been avoided with a proper voluntary dissolution at the time.
Can a Dissolved Corporation Be Revived?
Yes. Under the OBCA, a dissolved corporation can be revived. If a corporation is revived, it is generally restored to its previous legal position as if it had never been dissolved- meaning it regains all its rights, liabilities, and obligations from before dissolution.
Revival requires an application to the Director under the OBCA, payment of outstanding fees, and bringing all filings current. Courts and regulators treat revived corporations as if they had never ceased to exist, which can mean inheriting all the problems that led to dissolution in the first place.
This underscores why doing dissolution properly the first time is far less costly than dealing with revival later.

Dissolving a corporation in Ontario is not complicated, but it is detailed. Every step build on the previous one, and skipping steps especially around taxes, employee obligations, and CRA accounts can result in personal liability for directors long after the business has stopped operating.
If you are considering dissolving your Ontario corporation, the best first step is a conversation with a corporate lawyer and an accountant who understand the OBCA, CRA obligations, and the Ontario Business Registry process. Getting the right advice early makes everything that follows much smoother.
