What a Shareholder Agreement Does

A shareholder agreement is a private contract between the owners of an Ontario corporation that governs how the company is run, how decisions get made, and what happens when an owner wants to leave, sell, or is no longer able to continue. Unlike articles of incorporation or corporate by-laws, a shareholders' agreement is flexible, confidential, and tailored to the specific people and interests involved.

A well-drafted agreement governs the matters that most often cause disputes between shareholders:

  • Ownership and share structurewho owns what, how shares are issued, and pre-emptive rights on new issuances
  • Decision-making authorityvoting thresholds, board composition, and which decisions require unanimous consent
  • Transfer restrictionsrights of first refusal, permitted transfers, and approval requirements
  • Shotgun, drag-along, and tag-along clausesexit mechanisms when one shareholder wants out or a buyer wants in
  • Valuation and buy-sell provisionshow shares are valued on death, disability, departure, or dispute
  • Deadlock resolutionwhat happens when shareholders can't agree on a major decision
  • Confidentiality, non-compete, and non-solicitationprotecting the business from departing shareholders
  • Dividend and distribution policywhen and how profits are paid out

A shareholder agreement is not a template. The right agreement for a two-founder SaaS startup looks nothing like the right agreement for a family-owned professional corporation or a holdco bringing in outside investors. The clauses that protect you depend entirely on your ownership structure, your industry, and what you want to happen if things change.

When to Put a Shareholder Agreement in Place

Most founders only think about a shareholders' agreement when something has already gone wrong. By then, negotiating a fair agreement is far harder. The best time is at the beginning of a business relationship — when everyone is aligned, optimistic, and willing to agree on what fairness looks like.

Incorporating with co-founders

Starting a business with one or more partners is the single most common moment to put an agreement in place. Equity splits, vesting, decision-making, and exit terms should be documented before the company has revenue, IP, or value worth fighting over.

Bringing in investors

When a new shareholder buys in — whether a friends-and-family round, an angel investor, or a strategic partner — the agreement defines their rights, your protections, and how the relationship works going forward.

Family business succession

Multi-generational businesses face unique challenges when shares pass to children, in-laws, or non-active family members. A shareholder agreement keeps the business operational while honouring the family's wishes.

A shareholder is exiting or being bought out

When a co-founder, partner, or shareholder is leaving the business — voluntarily, due to a falling-out, retirement, or a triggering event — the exit terms determine the valuation, payment structure, non-compete obligations, and what happens to clients and IP. A separate exit or buy-out agreement is often required to document the specific terms of the departure.

Preparing for a financing round

Investors and lenders almost always require a current, well-drafted shareholder agreement before committing capital. Having one ready accelerates due diligence and signals professional governance.

Updating an outdated agreement

If your agreement was drafted years ago — or worse, downloaded from a template site — the clauses likely no longer reflect your current ownership, the value of the business, or Ontario's current legal framework.

Shareholder Agreement Drafting

We draft shareholder agreements from scratch for Ontario corporations. Every agreement is built around your specific ownership structure, your industry, and the relationship between the people involved. No templates, no generic clauses copied from American agreements, no boilerplate that leaves you exposed when it matters.

What's Included

  • Initial scoping consultation to understand your ownership, governance, and exit goals
  • Custom drafted agreement reflecting Ontario's Business Corporations Act (or the federal Canada Business Corporations Act for federal corporations)
  • All standard protective clauses: transfer restrictions, ROFR, drag-along, tag-along, shotgun, deadlock resolution
  • Valuation mechanism and buy-sell provisions tailored to your business
  • Plain-English explanation of every clause so you understand what you're signing
  • Up to two rounds of revisions based on your feedback and your co-shareholders' input
  • Final execution-ready document with signature blocks and witnessing instructions

Our Drafting Process

  1. 1
    Scoping call (20–30 minutes)

    We learn your structure, shareholders, industry, and what you want the agreement to protect. By the end of this call, we send you a flat-fee quote.

  2. 2
    First draft

    Custom-drafted agreement delivered, typically within 5–10 business days depending on complexity.

  3. 3
    Review and revisions

    We walk you through the draft clause by clause, answer questions, and incorporate feedback from you and your co-shareholders.

  4. 4
    Execution

    Final agreement is executed and stored. We remain available for questions as your business operates under the agreement.

Shareholder Exit & Buy-Out Agreements

When a shareholder is leaving the business — whether they want out, you want them out, or a triggering event has forced the issue — the terms of their exit can determine whether the business survives intact or is paralyzed for months. We draft and negotiate exit agreements, share buy-back agreements, and shareholder buy-out agreements that document the departure cleanly and protect the remaining shareholders.

When You Need an Exit or Buy-Out Agreement

  • A co-founder or partner has decided to leave the business
  • You want to buy out a shareholder who has become disengaged, disruptive, or non-performing
  • A shareholder is retiring and selling their interest back to the company or other shareholders
  • A shareholder has died, become disabled, or experienced another triggering event under your existing agreement
  • The original shareholder agreement's buy-out mechanism is being invoked and needs proper documentation
  • Two shareholders have reached a deadlock and one is exiting as the resolution
  • A shareholder is divorcing and matrimonial property issues are affecting their shares

What an Exit Agreement Documents

  • Valuationthe agreed-upon price for the departing shareholder's shares, including how it was determined (independent appraisal, formula, negotiation, or pre-existing buy-sell mechanism)
  • Payment structurelump sum, instalments, vendor take-back, earn-out, or some combination
  • Share transfer mechanicshow and when shares are transferred, escrow arrangements, and corporate filings
  • Releasesmutual releases protecting both the departing shareholder and the company from future claims
  • Non-compete and non-solicitwhether the departing shareholder can compete or solicit clients, employees, or suppliers, and for how long
  • Confidentialityongoing obligations regarding trade secrets, client information, and proprietary processes
  • Director and officer resignationsformal resignation from the board, officer positions, and any signing authorities
  • Personal guarantees and credit obligationsreleasing the departing shareholder from corporate guarantees, lease obligations, and lender covenants where possible
  • Outstanding loans, dividends, and accountssettlement of shareholder loans, declared but unpaid dividends, and intercompany accounts
  • Tax considerationscoordinating with your accountant on capital gains, section 84(2) deemed dividends, and any rollover provisions

If you have an existing shareholder agreement, the exit terms may already be partially defined — but the actual departure still requires its own documented agreement to record the specific transaction, releases, and post-departure obligations.

If there's no existing agreement, the exit is effectively negotiated from scratch under Ontario's Business Corporations Act default rules, which rarely produce a clean outcome. Either way, the exit agreement protects the remaining shareholders from future claims, locks in the valuation, and closes the chapter so the business can move forward.

Shareholder Agreement Review

If you've been handed an agreement to sign — by a co-founder, an investor, a family member, or a corporate counterparty — don't sign it without understanding what each clause means for you. Most disputes between shareholders trace back to a clause one party didn't fully understand when they signed.

What's Included in a Review

  • Full read-through of the agreement and all schedules
  • Written summary of risks, missing protections, and unusual clauses
  • Plain-English explanation of every section, including the parts that look like boilerplate but aren't
  • Specific recommendations for changes you should request before signing
  • Comparison against current Ontario corporate law and standard market practice
  • Follow-up call to walk you through findings and discuss negotiation strategy

Reviews are typically completed within 3–5 business days. If you're under time pressure, urgent turnaround is available — let us know during the scoping call.

Flat Fees, Quoted After a Scoping Call

Every shareholder agreement is different. A two-founder agreement with standard terms and a multi-shareholder agreement with investor protections, vesting, and complex transfer restrictions are entirely different engagements. Pricing every matter the same way wouldn't be fair to anyone.

We run a 20-minute scoping call to understand your structure, your shareholders, and your goals. After that call, we send you a flat-fee quote so you know the cost before any work begins. No hourly billing, no surprise invoices, no scope creep.

Common Engagement Types

Standard Two-Founder Agreement

Two co-founders, standard equity split, conventional transfer restrictions, drag/tag-along, and shotgun. Most startups and bootstrapped businesses fall into this category.

Flat fee quoted after scoping call
Most common

Multi-Shareholder with Investor Provisions

Three or more shareholders, including outside investors. Includes preferred share rights, anti-dilution, board representation, information rights, and customized exit mechanisms.

Flat fee quoted after scoping call

Family Business or Succession-Focused

Multi-generational ownership, voting and non-voting shares, succession provisions, estate-freeze coordination, and family-specific governance. Typically requires coordination with your accountant or estate lawyer.

Flat fee quoted after scoping call

Reviews of existing agreements are also flat-fee, quoted after a brief scoping call to confirm the length and complexity of the document.

Common Clauses Explained

A few clauses come up in nearly every shareholder agreement. Understanding what they actually do — and how they affect you — is the difference between an agreement that protects you and one that surprises you later.

Shotgun Clause

One shareholder offers to buy the other out at a stated price. The other shareholder must either accept the offer or buy the offering shareholder out at that same price. Forces fast resolution but heavily favours the shareholder with more cash on hand.

Drag-Along Rights

If a majority shareholder agrees to sell to a third-party buyer, they can compel minority shareholders to sell on the same terms. Protects the deal from being blocked by a small holdout, but can force a minority owner to exit on someone else's timeline.

Tag-Along Rights

The reverse of drag-along. If a majority shareholder sells, minority shareholders can "tag along" and sell on the same terms. Protects minority owners from being left behind in a deal negotiated without them.

Right of First Refusal (ROFR)

Before a shareholder can sell to an outside buyer, they must first offer the shares to existing shareholders on the same terms. Keeps ownership within the original group unless everyone declines.

Vesting and Reverse Vesting

Founders earn (or keep) their shares over time, typically 3–4 years. Critical for startups — without vesting, a co-founder who leaves after six months keeps their full equity stake forever.

Valuation Mechanisms

How shares are valued when a shareholder exits. Options include independent appraisal, formula-based (e.g., revenue or EBITDA multiple), book value, or pre-agreed annual valuation. The wrong mechanism can create years of disputes.

Common Questions About Shareholder Agreements

Questions Ontario business owners ask most often before booking a scoping call.

No. A shareholder agreement governs the relationship between two or more shareholders. If you're the sole shareholder, your articles of incorporation and corporate by-laws are sufficient. As soon as you bring in a second shareholder — whether a co-founder, a family member, or an investor — an agreement becomes essential.
Articles of incorporation are public documents filed with the government to legally create the corporation. They cover the basics: corporate name, share classes, directors. A shareholder agreement is a private contract between the shareholders that governs how they actually work together, make decisions, transfer shares, and exit. Both are needed — they do different things.
Most agreements are delivered in first draft within 5–10 business days of the scoping call. Total turnaround from scoping call to executed agreement is typically 2–4 weeks, depending on how quickly you and your co-shareholders provide feedback. Urgent turnaround is available when needed.
You can, but most templates marketed as "Canadian" are either generic forms that don't account for Ontario's Business Corporations Act, or they're imported American agreements with the country name swapped. Even legitimately Canadian templates can't reflect your specific ownership structure, share classes, voting thresholds, vesting terms, or the particular relationship between your shareholders. Ontario courts apply contract law strictly to shareholder agreements; vague, mismatched, or boilerplate language is exactly what gets challenged when a dispute starts. The cost of a properly drafted agreement is a fraction of the cost of litigation when a template fails.
Yes, when properly drafted. Shareholder agreements are contracts and are enforced under Ontario contract law and the Business Corporations Act. Enforceability depends on clear drafting, reasonable terms, and proper execution. Courts have consistently upheld well-drafted agreements and struck down those that are vague, overly broad, or unconscionable.
The corporation is governed by Ontario's Business Corporations Act default rules and the company's articles and by-laws. Those defaults rarely match what shareholders actually intended — especially for transfer restrictions, deadlock, and exit mechanics. Without an agreement, every dispute becomes harder, more expensive, and more unpredictable.
Pricing depends on the complexity of the ownership structure, the number of shareholders, and the specific provisions required. We quote a flat fee after a 20-minute scoping call so you know the full cost before any work begins. Most shareholder agreements fall within a predictable range — book a call to discuss yours.
Yes. Most agreements include an amendment provision specifying how changes can be made — typically requiring written consent of all shareholders, or in some cases a specified majority. Amending an agreement is straightforward when relationships are good; it's much harder once a dispute has begun, which is why getting the original drafting right matters.
A shareholder exit agreement (also called a buy-out agreement or share buy-back agreement) is a contract that documents the specific terms of a shareholder's departure from the corporation. It records the agreed valuation of the departing shareholder's shares, the payment structure, the transfer mechanics, mutual releases, ongoing non-compete and confidentiality obligations, and the resignation of any director or officer positions. An exit agreement is often required even when the original shareholder agreement already includes buy-out provisions, because the actual transaction needs its own documented terms, releases, and post-departure obligations.
The starting point is your existing shareholder agreement, if you have one — it typically defines the valuation method (independent appraisal, formula, or pre-agreed value), payment terms, and any restrictions on the buy-out. If there's no existing agreement, the buy-out is negotiated from scratch under Ontario's Business Corporations Act default rules, which rarely produce a clean outcome. Either way, the buy-out itself needs to be documented in a separate exit agreement that locks in the valuation, structures the payment, includes mutual releases, addresses non-compete and confidentiality obligations, releases the departing shareholder from corporate guarantees where possible, and coordinates with your accountant on the tax implications.
