Does CGL cover a data breach? The cyber and privacy gap for Canadian businesses

Usually not. Commercial general liability (CGL) policies in Canada typically exclude electronic data and, in many current wordings, the access or disclosure of confidential or personal information, and they never cover your own breach response costs. After a breach, a business may have to investigate, notify individuals and the privacy regulator under PIPEDA or, in Quebec, Law 25, restore systems and defend claims. Those costs belong to a cyber or privacy liability policy, and transfers tricked out of your bank account usually need crime or social engineering cover. Check your CGL wording for data exclusions, then decide whether the risk justifies a cyber policy.

This guide is part of the costly business insurance mistakes section. Figures are illustrative.

What the CGL does and does not do

EventCGL?Where cover usually sits
A hacker steals customer recordsUsually noCyber: breach response and privacy liability
Ransomware locks your systemsNoCyber: extortion, data restoration, business interruption
An employee emails a client list to the wrong personUsually no, under data disclosure exclusionsCyber: privacy liability

The personal and advertising injury part of a CGL may refer to the publication of material that violates a person's right of privacy. Many insurers have added exclusions so that this does not extend to data breaches. Read your policy's exclusions list rather than assuming either way.

What the law requires after a breach

RuleWho it applies toKey obligation
PIPEDA (federal)Private-sector organizations handling personal information in commercial activity, except where a substantially similar provincial law appliesReport breaches creating a real risk of significant harm to the Office of the Privacy Commissioner of Canada, notify affected individuals, keep records of all breaches for 24 months
Quebec's Law 25Businesses collecting personal information in QuebecReport confidentiality incidents presenting a risk of serious injury to the Commission d'accès à l'information and to affected persons; keep an incident register
Alberta PIPAPrivate-sector organizations in AlbertaNotify the Alberta privacy commissioner of breaches with a real risk of significant harm
British Columbia PIPAPrivate-sector organizations in BCPrivacy obligations; check the BC commissioner for current breach requirements
Health privacy lawsHealth custodians in several provincesSeparate breach rules, for example under Ontario's health information law

Quebec's Law 25 also introduced administrative monetary penalties and penal fines that can be substantial. Whether fines and penalties can be insured depends on the law and the wording; many policies cover them only "where insurable by law".

What a cyber policy usually covers

First-party costs (your own losses):

  • breach response: forensic investigation, legal advice, notification, call centre, credit monitoring
  • data restoration and system repair
  • business interruption from a network outage
  • cyber extortion, including negotiation, subject to legal limits
  • crisis communications

Third-party liability:

  • privacy and security liability claims by affected individuals or clients
  • regulatory investigations and defence, and penalties where insurable
  • payment card industry assessments, sometimes as a sub-limit
  • media liability for online content

Policies differ widely in sub-limits for ransomware, social engineering and business interruption, in waiting periods before business interruption is paid, and in security requirements such as multi-factor authentication and backups. Insurers commonly ask about these controls on the application, and misstating them can affect a claim; see disclosure and misrepresentation.

Worked example: a small breach

An illustrative Toronto physiotherapy clinic discovers that an attacker accessed its booking system, exposing records of about 4,000 patients.

CostIllustrative amount
Forensic investigation$28,000
Breach lawyer and regulatory reporting$18,000
Notification letters and call centre$9,000
Credit monitoring for those who accept it$14,000
Lost revenue while the system was offline$11,000
Defence of a claim by affected patients$40,000
Total$120,000

Under the clinic's CGL: probably nothing, given its data exclusion. Under an illustrative cyber policy with a $500,000 aggregate limit, a $5,000 retention and a 12-hour waiting period for business interruption: the clinic pays the $5,000 retention plus any revenue loss within the waiting period, and the policy pays most of the rest. Health information may also trigger obligations under the provincial health privacy law and the regulatory college's rules.

Deciding whether you need cyber insurance

Consider it seriously if you:

  • hold personal information about customers, patients, students or employees
  • take card payments or online orders
  • depend on systems you cannot run without for more than a day
  • pay suppliers by electronic transfer on email instructions
  • have contracts that require cyber cover

Before buying, ask the broker to explain each sub-limit, the retention, the waiting period and the security conditions, and compare at least two quotes. The quote preparation checklist covers the general process. Cyber policies are claims-made, so the retroactive date matters when you switch insurers; see claims-made gaps.

Frequently asked questions

My IT provider handles security. Am I still responsible for a breach?

Under privacy law, the organization that controls the personal information generally remains accountable, even if a service provider was involved. You may have a claim against the provider, but that does not remove your obligations.

Does cyber insurance pay ransoms?

Some policies cover extortion payments subject to legal restrictions, including sanctions laws, and insurer consent. Many insurers now expect strong backups and controls instead.

Is a small business really a target?

Automated attacks do not choose by size. The question is whether you could absorb the costs listed above without insurance.

Can I add cyber cover to my package policy?

Some insurers offer a cyber endorsement with modest limits. Compare its sub-limits with a standalone policy before deciding.
