Picture this: you agreed to serve as a director of your friend's growing company. It felt like a formality — a title, a favour, a show of support. Then a minority shareholder launched an oppression claim, named you personally, and your lawyer quoted you $40,000 just to respond to the initial proceedings. You had no idea that accepting a directorship meant accepting personal financial exposure.

Directors and officers insurance for small Ontario corporations exists precisely for this scenario. It is one of the least discussed but most practically important protections available to the people who run and govern private companies — and the misconception that it is only for large public corporations leaves many small business owners dangerously unprotected.

This article explains what D&O insurance is, what it covers and excludes, how Side A and Side B coverage work, and what to look for when evaluating a policy.

What Is D&O Insurance?

D&O insurance — short for directors' and officers' insurance — protects the individuals who govern and manage a corporation from personal financial loss when they are sued for decisions made in their capacity as directors or officers. It pays defence costs (legal fees, expert witnesses), settlements approved by the insurer, and judgments that arise from a "wrongful act" in the director or officer role.

This is important to understand: D&O insurance covers the person, not the company's products or operations. It fills a gap that a corporation's commercial general liability (CGL) policy typically does not touch. CGL policies cover bodily injury, property damage, and related third-party claims. Errors and omissions (E&O) or professional liability insurance covers claims arising from professional services rendered — a lawyer making a drafting mistake, a consultant giving bad advice. D&O insurance covers governance decisions: how the company was run, how it communicated with investors, whether directors exercised proper oversight.

What D&O Insurance Typically Covers

What D&O Insurance Typically Does NOT Cover

Exclusions vary between policies and must be read carefully, but the following are almost universally excluded:

  1. Fraud and wilful misconduct. Intentional wrongdoing is excluded in virtually every D&O policy. Insurance is designed for mistakes and misjudgments, not deliberate harm.
  2. Unremitted source deductions and unremitted HST. Under federal law, directors can be held personally liable for a corporation's failure to remit CPP contributions, EI premiums, income tax withholdings, and HST. Most D&O policies exclude statutory obligations or tax liabilities — meaning the assessment itself may not be insured, though defence costs during the process may be covered depending on how the specific policy is worded.
  3. Criminal fines and penalties. Insurers cannot indemnify against punishment. Criminal sanctions and regulatory penalties are excluded.
  4. Bodily injury and property damage. Those claims belong under your commercial general liability policy, not D&O.
  5. Claims by the corporation against its own directors. Some policies exclude or limit coverage when the company itself is the claimant — check whether your policy has an "insured versus insured" exclusion and how broadly it is drafted.

Side A vs. Side B Coverage

Most D&O policies are structured around two coverage sides, and understanding the difference matters for individuals personally.

Side A covers directors and officers directly when the corporation cannot or will not indemnify them. This happens when the company is insolvent and has no money to pay, or when the law prohibits indemnification in the particular circumstances. Side A is the coverage that stands between a director's personal assets and a judgment. For directors of small, potentially cash-strapped companies, this is arguably the most critical piece.

Side B reimburses the corporation after it has advanced funds to indemnify its directors and officers. The corporation pays first — legal fees, settlements, judgments — and then the insurer reimburses it under Side B. This protects the company's balance sheet, but the director has already been made whole by the company before the insurance steps in.

Many small private company policies blend both sides under a single limit. When evaluating your options, ask whether Side A has a dedicated, separate limit that cannot be eroded by Side B claims. A Side A-only policy with a dedicated limit is a meaningful upgrade in protection for individuals.

Why Small Private Corporations Should Care

The most common misconception about D&O exposure is: we are too small for anyone to bother suing us. That reasoning breaks down quickly when you consider how these claims actually arise:

Employment-related claims against individual directors have grown as employees become more aware of the personal liability rules that apply in the employment context. Director liability is not theoretical — it is a live risk for anyone who holds the title.

How D&O Complements (But Does Not Replace) Indemnification

The OBCA permits corporations to indemnify directors against costs incurred in litigation and settlements, subject to conditions — most importantly, that the director acted honestly and in good faith with a view to the best interests of the corporation. Many corporations make this commitment formal through indemnification provisions in their bylaws or through standalone indemnification agreements with individual directors.

But indemnification is only as good as the corporation's solvency. If the company runs out of money, loses a lawsuit, or enters insolvency proceedings, the director's right to be indemnified is effectively worthless. D&O insurance fills that gap — it is the financial backstop that ensures the indemnification commitment can actually be fulfilled, and it operates even in situations where indemnification by statute is not available.

You want both: a properly drafted indemnification provision in your corporate records and a D&O policy that funds it.

How to Evaluate a D&O Policy: A Practical Checklist

When reviewing a policy, work through these questions with your broker:

Frequently asked questions

Does my small corporation really need D&O insurance if we only have one or two directors?

Yes — in fact, a one- or two-director corporation can be more exposed than a larger company with a diversified board and deeper pockets. There is no minimum size threshold for personal director liability under the OBCA or federal law. Shareholder oppression claims, CRA director assessments, and employment-related claims do not spare small companies, and a one-director company has no one else to share the exposure with.

Will D&O insurance protect me from a CRA assessment for unremitted source deductions?

Probably not in full. Most D&O policies exclude claims arising from statutory obligations, including personal liability for unremitted payroll remittances and HST under the Income Tax Act and the Excise Tax Act. Depending on how your specific policy is worded, defence costs incurred during the assessment or objection process may be partially covered — but you should not count on the policy to cover the tax debt itself. Ask your broker directly and read the statutory obligation exclusion carefully before relying on this coverage.

How much does D&O insurance cost for a small private Ontario company?

Premiums vary widely based on the company's revenue, industry, number of directors, policy limits, coverage structure, and the insurer. As a general range (as of writing — verify with a broker), small private company D&O policies can start in the low hundreds to a few thousand dollars per year. It is typically far less expensive than most directors expect, and far less expensive than defending even a meritless lawsuit through to resolution.

Does D&O insurance replace the need for a proper indemnification agreement in our corporate records?

No — they work together. A properly drafted indemnification agreement or bylaw provision establishes the corporation's contractual obligation to stand behind its directors. D&O insurance is the financial mechanism that funds that obligation (or substitutes for it when the corporation cannot). If you have insurance but no indemnification provision, the corporation has made no formal commitment to its directors. If you have an indemnification provision but no insurance, the commitment is only as good as the company's bank account. You want both, and a corporate lawyer can make sure your minute book reflects the indemnification commitment properly.
