Professional Liability Insurance Requirements for Firms
Any firm engaged in the practice of public accounting or providing accounting services to the public must maintain professional liability insurance. The firm representative will need to provide proof of insurance to CPA Ontario in the following circumstances:
- when registering a firm
- annually as a part of the Annual Practitioner Dues (APD) filing
- when you stop engaging in the practice of public accounting or providing accounting services to the public (you will require a discovery policy/extended reporting period)
Please contact your insurance provider for detailed premium and coverage information. Make sure to check limits per claim as well as the aggregate limit and keep in mind that each provider may offer different features.
Important: Your insurance company, broker or agent does not communicate your insurance information to CPA Ontario. It is the responsibility of the firm representative to provide the firm's insurance information to CPA Ontario by reporting the information annually through My Portal.

How to report insurance
As a firm representative, you must report your insurance information to CPA Ontario during the Annual Practitioner Dues (APD) filing period through My Portal, by providing the following:
- insurance information as noted in your policy (i.e. policy number, limit of liability per claim, etc.)
- the source of coverage
- number of members in the firm
- effective and expiry date
- confirmation of coverage for all professional services
- confirmation of discovery insurance (extended reporting period)
Insurance information must be provided during the APD filing period (from mid-July to September 30 of each year) to CPA Ontario to maintain firm registration and membership in good standing as outlined in Regulation 14-1, section 11.
Failure to report insurance information during the APD filing period will result in the suspension of the firm and its firm representative. The firm has 30 days after the suspension to provide proof of insurance to reinstate the firm and Firm Representative. If the firm does not provide this, it will be deregistered and the firm representative’s membership will be revoked.
Prescribed levels of insurance
The minimum amounts of professional liability insurance apply to all firms engaged in the practice of public accounting or providing accounting services to the public. The required minimum limits are as follows, per claim:
- $1 million for a firm of one member
- $1.5 million for a firm of two or three members
- $2 million for a firm of four or more members
The maximum allowable deductible must be reasonable in relation to the total revenue of the firm and shall not be more than 50 per cent of the required minimum limit. Each firm must set aside assets (cash or cash equivalents) that are at least equal in value to the deductible amount specified in the professional liability insurance policy.
The minimum amount of professional liability insurance required to be maintained and maximum allowable deductible are set out in Regulation 14-1.
Firm representatives are reminded that their PLI must continue to cover all professional services conducted by the firm, including the Practice of Public Accounting or Providing Accounting Services to the Public.
Notification Requirements
Firms must notify CPA Ontario directly if PLI coverage is or becomes subject to any exclusion for an area of practice, expires, is cancelled, terminated or reduced below required limits.
Firms also must ensure their PLI policy requires the insurer to notify CPA Ontario of any exclusions from the required coverage for any areas of the firms practice.
Discovery policy requirements
Professional liability insurance in an unreduced amount must be maintained for at least six years after a member ceases to be involved in the practice of public accounting, providing accounting services to the public or the firm is dissolved.
Should a member pass away, the estate should maintain coverage for the six-year discovery period. To provide these details, contact the Firms and Licensing team.
Discovery policy can also be referred to as “an extended report period”.
More specific details on the circumstances are provided in Regulation 14-1.
Providing charitable assurance services without reward
Members who engage in the practice of public accounting without reward, under certain conditions, do not need to be licensed. However, you must still have professional liability insurance coverage.
If you are a member providing assurance services without reward for small charitable or not-for-profit organizations, CPA Ontario has approved a policy to provide insurance coverage at no cost. You must register with CPA Ontario and meet certain terms and conditions.
One of the conditions is that each organization has annual gross revenue from all sources of $100,000 or less. Members who provide assurance services without reward for organizations that have annual gross revenue of more than $100,000, or who otherwise do not meet the prescribed terms and conditions, must obtain their own insurance coverage.
See Public Accounting Licence for more information on the exemption and how to apply for the policy arranged by CPA Ontario. For any further questions, please contact the Firms and Licensing team.
Professional Liability Insurance FAQs
The amendments to Regulation 14-1: Professional Liability Insurance take effect on July 1, 2026. Firm representatives will be required to report their PLI policy information on an annual basis as part of the Annual Practitioner Dues (APD) submission process, with a deadline of September 30 each year. Firms will no longer be required to report PLI within five business days of the policy expiry.
In addition to the change in reporting framework, there are new notification requirements also effective July 1, 2026, including:
- Firms must notify CPA Ontario directly if PLI coverage is or becomes subject to any exclusion for an area of practice, expires, is cancelled, terminated, or reduced below required limits, and
- Firms must ensure their PLI policy requires the insurer to notify CPA Ontario of any exclusions from the required coverage for any areas of the firms practice.
Firm representatives are reminded that their PLI must continue to cover all professional services conducted by the firm, including the Practice of Public Accounting or Providing Accounting Services to the Public.
Effective July 1, 2026, PLI reporting on My Portal will no longer be available, and will be reported annually via the APD submission.
Any PLI information previously reported for your current policy year will remain on file with CPA Ontario. You will be required to report your PLI again as part of your APD filing, available on July 16, 2026. We appreciate your patience and cooperation during this transition.
If your PLI expires, is cancelled, terminated, reduced, or subject to any exclusion during this period, firms must notify CPA Ontario directly in accordance with Regulation 14 1. Please contact the Firms & Licensing Team at [email protected].
If your PLI is renewed with no break in coverage and no reduction in terms, you do not need to notify CPA Ontario at the time of renewal. You will be required to report your current PLI information as part of the yearly APD filing.
Members who engage in the practice of public accounting without reward, under certain conditions, are exempted by Ontario Regulation 238/05 from the requirement to be licensed. However, members who provide these services are required to have professional liability insurance coverage.
The minimum professional liability insurance (PLI) limits exist to protect the public interest and to reflect the current coverage levels already carried by many firms.
