Read before you sign: Ontario leases, contracts, and share agreements.

Ontario business owners sign documents they have not read. Commercial leases, shareholders agreements, supplier contracts, director resolutions: each one transfers legal control, and each one is enforceable in Ontario courts whether or not the owner read the page they signed. The standard form is usually long, written in plain font, and carries the levers that matter most on pages eighteen through twenty-five.

A signed document binds the company and, in many cases, the owner personally. Ontario law treats the signature as consent to every clause above it. The defence that “I did not read it” generally does not work.

This guide covers the four document types where reading before signing matters most for an Ontario business owner. Commercial leases. Shareholders agreements. Commercial contracts. Corporate resolutions. Each section names the levers that the standard form gives to the other side, and the negotiating room that owners frequently miss.

Why a signature equals consent in Ontario contract law.

Ontario contract law treats a signature as a confirmation that the signing party agrees to the terms of the document. The legal principle is straightforward: a signed contract is enforceable unless the signing party can show that the signature was obtained through fraud, duress, or a misrepresentation about what the document was.

The owner who signs without reading carries the legal risk of every clause above the signature line. The lease term is binding. The personal guarantee is binding. The non-compete is binding. The indemnity is binding. Each of those clauses produces consequences when the relationship hits friction, often years after the document was signed and put away.

Three narrow defences exist:

• Misrepresentation about the nature of the document (someone said it was a lease when it was a guarantee)
• Duress (the party was forced into signing under threat)
• Unconscionability (the bargain was so one-sided that a court will set it aside)

Each defence carries a high evidentiary burden. None of them protect against simply choosing not to read what the document says.

Commercial leases: the five clauses every Ontario owner should read.

Commercial leases run five to ten years on average, and carry committed rent of $300,000 to $1.5 million over the term for a typical Ontario small business location. Five clauses inside the standard lease form decide how that commitment behaves when the business hits stress.

• The personal guarantee binds the owner's personal assets to the landlord's claim
• The renewal clause sets the terms on which the tenant can extend
• The demolition clause lets the landlord terminate early to redevelop
• The relocation clause lets the landlord move the tenant within the building
• The default and cure period defines the timeline for fixing a missed payment

Each clause is negotiable before signing. The standard form gives most of the levers to the landlord, but the standard form is not a final form. Owners who read and negotiate before signing reshape the lease around their business plan rather than the landlord's redevelopment plan.

Shareholders agreements: the four provisions that shape who controls the company.

Shareholders agreements decide how the cap table behaves when partners disagree, when a founder leaves, when an investor wants out, or when the company sells. The agreement is written between the shareholders, not between the shareholders and the company. Without it, Ontario corporate law fills in the defaults: equal voting per share, no vesting, no buy-out at departure, no protection against dilution.

Four provisions shape the actual control of the company.

Voting and decision rights.

The agreement specifies which decisions require a simple majority, a supermajority, or unanimous consent. Founder-level decisions (issuing new shares, taking on debt, selling the company, paying dividends) belong in the supermajority or unanimous bucket. Operating decisions belong in the simple-majority bucket. Without this allocation, every decision defaults to simple majority, which gives whichever shareholder holds 51 percent the operational control of the company.

Vesting and founder departure.

Vesting decides what happens to a founder's shares if the founder leaves the company before a defined date. A typical vesting schedule unlocks shares over four years with a one-year cliff. Without vesting, a co-founder who departs in month two of the company still owns whatever portion of the cap table was issued at incorporation. With vesting, those shares return to the company on departure.

Drag-along and tag-along rights.

A drag-along right lets the majority shareholders force minority shareholders to sell on the same terms if the company is sold. A tag-along right lets minority shareholders sell on the same terms if the majority sells. Both are standard in shareholders agreements and both protect different parties. Without them, a sale of the company can deadlock or leave minority shareholders stranded.

Buy-sell triggers.

Buy-sell provisions set the terms on which a shareholder can leave (or be removed from) the cap table. The agreement names the triggering events (death, disability, departure, deadlock), the valuation method (book value, market value, formula), and the payment terms (lump sum, installments, holdback). Without buy-sell terms, exits become litigation.

The shareholders agreement is the document that decides what happens when the founders disagree about a hire, a raise, a sale, or a strategy. Ontario corporate law fills in defaults that favour whoever holds 51 percent. The agreement reshapes those defaults around what the founders actually want.

Commercial contracts: the three clauses that decide what happens when things go wrong.

Commercial contracts (supplier agreements, service contracts, vendor terms, NDAs, distribution agreements) carry the same enforceability as the lease. Three clauses matter most when the contract hits friction.

Indemnity.

The indemnity clause names which party pays for which losses if a third party brings a claim. Standard forms often give the other side a broad indemnity from the owner, covering not only the owner's own conduct but also conduct that the owner had nothing to do with. Reciprocal, capped, and conduct-limited indemnities are standard in negotiated commercial contracts.

Limitation of liability.

The limitation of liability clause caps how much one party can recover from the other if something goes wrong. Standard forms often cap recovery at the value of the contract (modest) and exclude consequential damages (significant). Owners who sign without reading the limitation clause accept whatever cap the other side wrote.

Termination.

The termination clause names how and when each party can end the contract. Termination for cause, termination for convenience, notice periods, and survival of obligations after termination all sit inside this clause. Standard forms often give the larger party a unilateral right to terminate for convenience while requiring the smaller party to show cause. Each piece is negotiable.

A commercial contract that runs three years and produces $200,000 of revenue is a small business decision. Three clauses inside that contract decide how exposed the owner is when the deal goes wrong.

Resolutions and corporate documents: the records that hold up under audit, financing, or sale.

Corporate resolutions document the decisions of the company. Director resolutions authorize the directors' acts. Shareholder resolutions authorize shareholder-level decisions. Resolutions to issue shares, declare dividends, approve loans, change officers, appoint auditors, sell assets all live in the minute book.

The owner who signs corporate resolutions without reading carries a different risk than the owner who signs an external contract. The resolution binds the company internally and creates the record that auditors, lenders, buyers, and the Canada Revenue Agency will look at when they examine the company.

Three patterns matter:

• Resolutions that authorize the issuance of shares change the cap table. Reading the resolution before signing confirms that the share class, the share count, and the recipient match what was agreed
• Resolutions that authorize loans bind the company to repayment terms. Reading the resolution before signing confirms the lender, the principal, the rate, and the term
• Resolutions that declare dividends affect tax treatment for the recipients and the cash position of the company. Reading the resolution before signing confirms the amount, the timing, and the share class

Corporate records that hold up under outside scrutiny require resolutions that match what actually happened. Resolutions signed without reading often diverge from the underlying transaction, and the divergence surfaces years later when a buyer, an auditor, or the CRA asks for the minute book.

The DRG written brief applied to any document.

DRG Law applies the same five-line brief to every document before the client signs. Risk, cost, timeline, decision, next step. The brief is short by design. It forces the owner to confront the actual stakes of the signature before the signature happens.

Risk.

What exposure does this document create for the owner personally and for the company? Name the dollar figure, the timeline, and the asset reach.

Price.

What does this document commit the owner to pay? Include the headline amount, the additional costs (taxes, fees, indemnities), and the worst-case payout.

Timeline.

When do the commitments start and end? Include the term, the renewal options, the termination notice, and the calendar dates that matter.

Decision.

What is the actual business decision this document supports? The lease supports a business location. The shareholders agreement supports a partnership structure. The contract supports a customer relationship. The resolution supports a corporate move.

Next step.

What does the owner need to do or decide next? Sign as drafted. Negotiate specific clauses. Walk away. Get a second opinion.

Five lines. Every matter. Every document. The frame is the same whether the document is a one-page resolution or a forty-page lease.

What this means before you sign anything.

Every signature is a transfer of legal control. The document writer designed the clauses to allocate risk in their favour. The standard form is a starting position, not a final position. Reading before signing is the cheapest and fastest way to understand what is being transferred.

The cost of a fifteen-minute legal review on a document the owner does not understand sits between $250 and $750. The cost of a five-year mistake on a clause the owner did not read can sit between $50,000 and several million dollars. The math is simple. The friction in actually doing the review is what gets in the way.
