A corporate minute book is the master record of your corporation: who owns it, who runs it, and every significant decision it has made since incorporation. Under section 140 of Ontario’s Business Corporations Act, every Ontario corporation is required to prepare and maintain these records, either at its registered office or at another Ontario location the directors designate.
It is also, by a wide margin, the most neglected document in Canadian small business. Nobody thinks about the minute book until a buyer, a bank, or the CRA asks for it. By then, the gaps are expensive.
What Is a Corporate Minute Book?
Despite the name, it is not a single book. It is a collection of records, traditionally kept in a binder and increasingly kept digitally, that together prove the corporation’s legal existence, ownership, and governance history.
Think of it as the corporation’s paper trail. The government knows your corporation exists. The minute book proves everything else: who was issued shares and when, who sits on the board, what by-laws govern, and what the directors and shareholders actually decided each year.
What an Ontario Minute Book Must Contain
Section 140(1) of the OBCA sets the required records:
- The articles of incorporation, the by-laws, and all amendments to both
- A copy of any unanimous shareholder agreement known to the directors
- Minutes of meetings and resolutions of shareholders
- A register of directors, with the dates each person became or ceased to be a director
- A securities register complying with section 141, showing who holds which shares
- A register of ownership interests in land under section 140.1
- A register of individuals with significant control under section 140.2, often called the transparency register
Section 140(2) adds adequate accounting records and the minutes and resolutions of the directors and any board committees. A well kept book also holds the share certificates themselves, a register of officers, and copies of the Initial Return and Notices of Change filed with the Ontario Business Registry.

Incorporation, contracts and advice on flat fees. Plain language, no billable-hour surprises.
What a Lawyer Checks First When Reviewing Your Book
When we review one, the order is deliberate.
First, the share register and the certificates. Does what was actually issued, paid for, or transferred match what the register says? Ownership is the thing every deal turns on, so it gets checked before anything else.
Second, the director and officer registers against what is actually on file with the government. Mismatches between the book and the public record are common and easy to spot.
Third, whether annual resolutions exist for every year: approving the financial statements and electing the directors and officers. Missing years here are usually the first sign of a stale book, because they mean nobody has touched it since the lawyer who incorporated the company handed it over.
Why It Matters: Buyers, Banks and the CRA All Ask For It First
The minute book is usually the first document requested in due diligence when you sell the company or raise investment. Lenders often ask for it before advancing funds. The CRA can request corporate records in an audit, and anyone examining the corporation is relying on the book to show who owns and controls it. The OBCA itself makes the records open to examination by directors under section 144 and by shareholders under section 145.
When the book cannot answer the ownership question cleanly, deals do not usually die. They stall, and the meter runs while lawyers reconstruct history under deadline pressure.
A Real Example: The Handshake Buyout That Stalled a Seed Round
Names withheld, but the sequence is real. A two person Ontario tech company incorporated in 2021 with a proper minute book: articles, by-laws, shares issued to both founders. A year later, one founder bought the other out in a quick, informal deal. They signed a simple bill of sale between themselves, the money moved, and everyone got on with their lives. Nobody updated the share register, passed a directors’ resolution approving the transfer, issued a new certificate, or cancelled the old one.
Three years later the remaining founder went to raise a seed round. The investor’s lawyers asked for the minute book, and the register still showed both original founders as 50/50 shareholders, with nothing documenting the transfer. To investor counsel, that is genuine ambiguity about who owns the company, and a verbal explanation does not fix it.
The round closed, but weeks late. A lawyer had to reconstruct the transaction after the fact, track down the departed business partner for confirmatory documents and a release, and prepare the resolutions and updated register that would have taken minutes at the time. The legal fees bought the company nothing it should not already have had.
Annual Maintenance: The Ten Minutes a Year That Prevent the Mess
Keeping it current is not onerous. Each year, the directors and shareholders pass annual resolutions approving the financial statements and electing directors and officers. When a director, officer, or address changes, a Notice of Change gets filed with the Ontario Business Registry and the registers get updated. When shares move, the transfer is approved by resolution, the register is updated, and certificates are issued and cancelled.
Done contemporaneously, each of these is a small task. Done retroactively under due diligence pressure, they become a reconstruction project.
Digital or Physical? What We Recommend in 2026
The OBCA does not require a paper binder. Under section 139(1), a record required by the Act may be kept in any form, and section 139(2) adds the conditions: the corporation must guard against falsification and be able to produce the information in an accurate and intelligible form within a reasonable time.
In practice, that makes a digital minute book fully valid in Ontario, and for most corporations it is now the sensible default: encrypted, access controlled, backed up, and available instantly when a lender or buyer asks. A hybrid setup earns its keep mainly where an outside party insists on paper, most often a lender or investor who wants physical share certificates they can hold.
Fixing Years of Neglect: Minute Book Remediation
If your book has not been touched since incorporation, the fix is called remediation: tracing every share movement since day one, preparing the confirmatory resolutions that should have existed, obtaining releases from departed shareholders where needed, rebuilding the registers, and bringing government filings current.
We offer this at Angrove Law. Cost depends on the type of business and how much has happened since the book went quiet. Our usual approach is an initial assessment at $300, followed by a flat rate for the reconstruction once we can see the scope, with hourly billing at $300 per hour where a flat rate does not fit. Compared with what an unresolved ownership question costs in the middle of a deal, it is cheap insurance.
If you are incorporating now, the easier path is starting clean: our business incorporation service sets up the minute book properly from day one.
Frequently Asked Questions
Is a minute book required by law in Ontario?
Yes. Section 140 of the Business Corporations Act requires every Ontario corporation to prepare and maintain corporate records, including articles, by-laws, minutes, resolutions, and share registers. There is no exemption for small or single shareholder corporations.
Can a minute book be digital in Ontario?
Yes. Section 139(1) of the OBCA allows required records to be kept in any form, provided the corporation guards against falsification and can produce the information in an accurate and intelligible form within a reasonable time. Secure, backed up digital books are now common practice.
What happens if my corporation has no minute book?
Nothing, until someone asks for it. Then a sale or financing can stall while records are reconstructed, lenders can hesitate, CRA reviews get harder, and ownership disputes become difficult to resolve because nothing was written down.
How much does it cost to fix a neglected minute book?
It depends on how many years and transactions need reconstructing. At Angrove Law, remediation typically starts with a $300 assessment, followed by a flat rate for the work once the scope is clear.
