How do I dissolve a corporation in Ontario?

Why the order of operations matters

Dissolving a corporation properly means winding it down before winding it up on paper. Debts get paid first, because directors can face personal liability for certain unpaid amounts, including payroll source deductions and GST/HST, if the corporation is dissolved while those are still outstanding. Only after creditors are dealt with does the remaining value belong to the shareholders, and only after that distribution is the corporation actually empty and ready to be legally ended. Doing this in the wrong order, or skipping steps because the corporation "isn't doing much anyway," is where most voluntary dissolutions go sideways.

Before any of this starts, it is worth confirming the corporation has actually stopped operating in every sense a lender, landlord, or supplier would recognize: no open leases, no ongoing contracts, and no equipment or inventory still tied up in the business. A corporation that dissolves while a lease or contract is still technically active can leave the shareholders, rather than the corporation, exposed to whatever obligation was left unresolved, which defeats much of the point of having incorporated in the first place.

How the final distribution to shareholders is taxed

When a corporation winds up, the amount paid out to shareholders in excess of the paid-up capital of their shares is generally treated as a deemed dividend, taxed the same way an ordinary dividend would be. Whatever is left after backing out the deemed dividend is treated as proceeds of disposition of the shares, which produces a capital gain or capital loss under the wind-up provisions in subsection 88(2) of the Income Tax Act. This two-part character, part dividend and part capital transaction, is exactly why the shareholder-level tax on a dissolution should be modelled before the assets actually move, not discovered afterward on the personal return.

The mix between the two pieces depends on what the corporation is actually distributing. A corporation with mostly cash and retained earnings built up over the years tends to produce a larger deemed dividend component, while a corporation whose value sits in an appreciated capital asset can produce a larger capital gain component instead. Since dividends and capital gains are taxed differently in the hands of the shareholder, working out this split in advance, rather than after the corporation is already gone, is what lets an owner plan around it rather than simply accept whatever number the final return produces.

Closing out the corporation's CRA accounts

A dissolving corporation files a final T2 return covering the short period ending on the actual dissolution date, checking the box that identifies it as the corporation's final return. Any GST/HST account needs a final return and formal closure, and a payroll account needs final remittances and a Record of Employment for any remaining employees before it is closed. Leaving these accounts open after the corporation is legally dissolved is a common source of CRA notices sent to a mailing address no one is checking anymore, so closing them in the same window as the wind-up avoids that entirely.

Filing the articles of dissolution

Once debts are settled and assets are distributed, the corporation files articles of dissolution through the Ontario Business Registry. Ontario's process has been streamlined since the registry launched, and Ministry of Finance consent that older dissolutions sometimes required is no longer part of the standard process in most cases, though we would confirm the current requirement for your corporation's specific situation before assuming no consent is ever needed. Once the articles are filed and accepted, the corporation ceases to exist as a legal entity, and its name becomes available for someone else to use.

Records retention after dissolution

Dissolution does not erase the recordkeeping obligation. Directors and former officers should keep the corporation's minute book and financial records for at least two years after dissolution, since the CRA can still reassess a return filed while the corporation existed, and having the records on hand is far easier than trying to reconstruct them later. Keep the final T2, the GST/HST closure confirmation, and the articles of dissolution together as the core file for that retention period.

This applies even to directors and officers who assume their responsibility ends the moment the corporation stops existing. If the CRA reassesses a return from a year the corporation was still active, it can still pursue that reassessment after dissolution, and having the supporting records on hand is the difference between a straightforward response and a scramble to reconstruct years-old documentation from memory or scattered files.

Why letting a corporation lapse is worse than dissolving it properly

Some owners simply stop filing an annual return and assume the corporation will quietly disappear on its own. It eventually can, through administrative dissolution by the registry, but that path skips the orderly wind-up entirely: debts are not necessarily settled first, the shareholder-level tax on any remaining assets is never properly worked out, and reviving an administratively dissolved corporation later, if it turns out to still be needed, is its own process with its own cost. A deliberate dissolution, done in the right order, is almost always cleaner and cheaper than an accidental one.

How we handle this

We model the shareholder-level tax on a wind-up before any assets move, prepare the final T2 and close the CRA accounts in the same window, and coordinate the articles of dissolution filing so nothing is left open after the corporation is gone. This is part of our incorporation and compliance services for owners who are closing a corporation rather than starting one.
