Constating documents are the records that create a corporation and set the rules for how it runs. In Canadian corporate law the term covers three instruments: the articles of incorporation, the bylaws, and any unanimous shareholder agreement.1Corporations Canada. Glossary for the Canada Business Corporations Act American law uses the same underlying documents but normally calls them formation or organizational documents. Whatever the label, these are the papers a bank, a court, a tax authority, or a buyer of your shares will ask to see.
The Three Documents and What Each One Does
The articles of incorporation are the public filing that brings the corporation into legal existence. Under the Canada Business Corporations Act, a corporation exists on the date shown in the certificate of incorporation issued by the Director after the articles are filed.2Justice Laws. Canada Business Corporations Act RSC 1985 c C-44 – Section 9 Before that certificate issues, the business has no legal personality and cannot sign contracts or hold property in its own name.
The bylaws are the private operating manual. They are not filed with the government. They sit in the corporation’s own records and tell directors, officers, and shareholders how to actually run the company day to day.
A unanimous shareholder agreement is optional, but when one exists it is the most powerful of the three. It is a written contract signed by every shareholder that can strip management powers away from the board and move them to the owners. The articles say what the corporation is. The bylaws say how it is run. The shareholder agreement says who is really in charge.
What the Articles Must Contain
Section 6 of the CBCA fixes the mandatory contents of the articles.3Justice Laws. Canada Business Corporations Act RSC 1985 c C-44 – Section 6 You need to decide and record:
- The exact corporate name.
- The province where the registered office will be located.
- The classes of shares the corporation can issue, any maximum number, and the rights and restrictions attached to each class if there is more than one.
- Any restrictions on who can hold or transfer shares.
- The number of directors, or a minimum and maximum range.
- Any limits on the business the corporation may carry on.
The articles may also include anything the Act permits in the bylaws. Putting a rule in the articles entrenches it, because articles are harder to amend than bylaws. Founders who want certain governance rules to be difficult to change later move them up into the articles for exactly that reason.
Share structure is the decision that most often gets botched. A single class of common shares is simple. Multiple classes with different voting rights, dividend entitlements, and redemption terms give flexibility for tax planning, estate freezes, and bringing in investors, but they also have real tax consequences. This is the point in the process where paying for professional advice is cheaper than fixing a mistake later.
What Bylaws Actually Control
Bylaws govern the internal machinery: how board meetings are called and conducted, what notice shareholders get before a meeting, the quorum needed for a valid vote, how officers are appointed and removed, who can sign contracts for the corporation, and how director conflicts of interest are handled.
Voting thresholds are where bylaws have real teeth. The statutory default is a simple majority for most decisions. Bylaws (or the articles, or a unanimous shareholder agreement) can require more. Two-thirds or three-quarters supermajorities are common for removing a director, amending the articles, or approving a major asset sale. The CBCA expressly permits the articles or a unanimous shareholder agreement to require a greater number of votes than the Act itself requires, and that heightened requirement overrides the statutory default.3Justice Laws. Canada Business Corporations Act RSC 1985 c C-44 – Section 6
Vague bylaws create expensive fights. A loose notice provision gives a disgruntled shareholder grounds to challenge a decision they lost on. The goal when drafting is specificity: tight enough to settle disputes before they escalate, loose enough that normal business does not require constant amendments.
Why a Unanimous Shareholder Agreement Changes the Picture
Section 146 of the CBCA says that a written agreement among all shareholders that restricts the directors’ management powers is valid and binding, including on anyone who later buys shares.4Justice Laws. Canada Business Corporations Act RSC 1985 c C-44 – Section 146 When the shareholders take those powers, they also take on the legal duties and liabilities that would otherwise sit with the directors. Control and responsibility travel together.
These agreements typically cover:
- Buy-sell provisions governing what happens when an owner wants out, retires, becomes disabled, or dies.
- Transfer restrictions and rights of first refusal, forcing a seller to offer shares internally before going to outsiders.
- Dispute resolution through mediation or arbitration instead of litigation.
- Consent requirements for major decisions such as mergers, new share issuances, or changes in business direction.
One trap deserves a direct warning. Anyone who buys shares subject to a unanimous shareholder agreement is automatically deemed a party to it. If the seller does not disclose the agreement, the buyer has 30 days from learning of it to rescind the purchase.4Justice Laws. Canada Business Corporations Act RSC 1985 c C-44 – Section 146 If you are buying into a private corporation, ask for the constating documents in writing before you sign anything.
Keeping the Documents Alive After Filing
Filing the articles is the start, not the finish. Every federal Canadian corporation must file an annual return with Corporations Canada. The online fee is $12, and skipping it can get the corporation administratively dissolved.5Corporations Canada. Annual Return Losing a corporation over a missed $12 filing is embarrassing, and it happens.
American corporations face the same pattern. Most states require an annual or biennial report updating the registered agent, principal office, and names of directors and officers. Miss it and you get late fees, loss of good standing, and eventually administrative dissolution. A dissolved corporation cannot sue, cannot contract, and cannot protect its own name.
After the certificate of incorporation issues, the corporation should immediately adopt bylaws at the first directors’ meeting, issue share certificates, appoint officers, and open a minute book. The minute book is the binder, physical or digital, that holds the constating documents, meeting minutes, share registers, and director resolutions. Lawyers, auditors, and banks will ask for it throughout the life of the company.
Keep it current. Every board or shareholder meeting generates minutes that belong in the book. Significant corporate actions get documented by resolution. Amending the articles themselves requires a separate filing with the government, usually a board resolution followed by a shareholder vote.
When a bank, lender, or buyer wants proof that the corporation is in good standing, you request a certificate of good standing (also called a certificate of status or certificate of existence) from the filing authority. In Canada, Corporations Canada issues them for federal corporations. In the United States, the relevant secretary of state does, for a small fee.
Where Your Documents Will Be Tested
Three places will put your constating documents under real scrutiny: your bank, your tax authority, and, if things go wrong, a court.
Banks have a legal duty to verify who they are dealing with. In Canada, the Proceeds of Crime (Money Laundering) and Terrorist Financing Act requires institutions to verify a corporation’s existence using a certificate of incorporation, a record filed under provincial securities legislation, or another current record confirming the name, address, and directors.6FINTRAC. Methods to Verify the Identity of Persons and Entities In the United States, the Beneficial Ownership Rule requires banks to identify and verify the beneficial owners of any legal entity opening a new account, collecting each one’s name, date of birth, address, and identification number.7FFIEC. FFIEC BSA/AML Assessing Compliance with BSA Regulatory Requirements – Beneficial Ownership Requirements for Legal Entity Customers If the names on your articles and share register do not match the people in front of the banker, the account does not open.
Tax authorities use your formation documents to classify the entity and connect income to the right people. A U.S. LLC with two or more members is taxed as a partnership by default, and a single-member LLC is a disregarded entity, but either can elect a different classification on IRS Form 8832.8Internal Revenue Service. About Form 8832, Entity Classification Election The share structure and ownership percentages in your constating documents directly affect which elections are available and how income flows out to the owners. The same is true in Canada, where share structure drives whether tools like estate freezes and family income splitting are available to a private corporation.
Courts are the last place these documents get tested, and the stakes are highest. The whole reason people incorporate is to keep personal assets separate from business liabilities. Courts can pierce the corporate veil and hold shareholders personally liable when the corporation looks indistinguishable from its owners. Mixing personal and business funds, undercapitalizing the corporation at startup, and ignoring corporate formalities are the classic warning signs. Failing to hold meetings or keep minutes may not be enough on its own to pierce the veil in every jurisdiction, but it is routinely used as evidence that the corporation and its owner are the same thing. A corporation with no bylaws, no minutes, and no resolutions looks less like a legal person and more like a personal account with a fancier name.
Beyond liability, incomplete records create everyday friction. A corporation that cannot produce current constating documents will stall on real estate closings, government contract bids, extra-provincial or multi-state registrations, and acquisition due diligence. The cost of avoiding all of this is small: an annual meeting, minutes in the book, a current share register, and the annual return filed on time. Reconstructing records after years of neglect, or defending a veil-piercing claim, costs thousands.
A Note on US Terminology
If you are incorporating in the United States, you will not hear the phrase “constating documents” in day-to-day practice. The same three functions still exist. The articles of incorporation (or articles of organization for an LLC) are filed with the secretary of state in the state of formation. Bylaws (or an operating agreement for an LLC) handle internal governance. Shareholder agreements and LLC operating agreements do the work of a unanimous shareholder agreement. The mechanics shift by state, but the structure a reader needs to understand is the same.
