Annual Corporate Maintenance Checklist (Ontario)

The yearly housekeeping that keeps your corporation in good standing — and ready for anything.

Last reviewed 2026-06

A once-a-year checklist to keep your Ontario corporation compliant, current, and financing-ready.

Who this is for + what you'll get: Owners, directors, and officers of an Ontario corporation who want to stay on top of yearly obligations. You'll get a grouped checklist of everything a corporation should do each year — filings, meetings, records, registers, and reviews — with a short "why it matters" on the items people most often miss.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.


Why annual maintenance matters

A corporation isn't "set and forget." It's a living legal entity that must be maintained every year to stay in good standing. Skip the upkeep and you risk lapsed filings, an out-of-date public record, and — at the extreme — involuntary dissolution by the government, which is a real hassle to reverse.

There's a second reason that matters even more day to day: records. The moment you seek a loan, take on an investor, or sell the business, the other side runs due diligence — they comb through your minute book and filings. Clean, current records make that process smooth and protect your value. Messy ones cause delays, price reductions, and sometimes a dead deal.

💡 Set a recurring annual reminder (tie it to your fiscal year-end or incorporation anniversary) and run this checklist each year. An hour of housekeeping now saves days of cleanup later.


1. Government filings


2. Annual meetings (or resolutions in writing)


3. The minute book


4. Transparency register (individuals with significant control)


5. Canada Revenue Agency filings


6. Licences, permits, and insurance


7. A quick housekeeping review

📌 The "financing-ready" test: If a lender or buyer asked for your records tomorrow, could you hand over a complete, current minute book, up-to-date registers, your last annual return, and proof of tax filings — without scrambling? If yes, your maintenance is working. If not, this checklist tells you exactly what to fix.


What's next

Run this checklist once a year and keep a simple compliance calendar of your deadlines (annual return, tax filings, licence renewals, insurance review). If you've fallen behind — missed annual returns, a minute book that hasn't been touched since incorporation, a stale ISC register — don't panic. These are routine to clean up, and far easier to fix before a financing or sale than during one.
