Only LPAs can sign — start here

If a bank, condominium board, non-profit stakeholder, franchisor, credit union, or acquisition target has asked you for audited or reviewed financial statements, your first sorting question is not “which CPA” — it is “which Licensed Public Accountant.” Under Ontario’s Public Accounting Act, 2004, only a CPA who additionally holds a valid Public Accounting Licence (PAL, colloquially the LPA) may issue an audit report, a review engagement report, or a compilation report that a third party is reasonably expected to rely upon.

Any CPA who does not hold the PAL and offers to sign an audit or review report in Ontario is operating outside the statute. Any firm that markets audit or review capability without a licensed lead engagement person is misrepresenting scope. Both scenarios expose the client — you — to the risk that the resulting report is legally invalid for the purpose it was requested for. That is not an abstract risk: your bank can refuse to accept the report, your condominium board can be required to reissue statements, your acquirer can walk from the deal.

This guide teaches the criteria to shortlist any LPA in Ontario in 2026 — verification, insurance, inspection history, sign-off scope, and industry fit. It is written for owners, board members, treasurers, and CFOs who have already determined that an LPA is required and now need a way to choose one. If you are still working out whether you need an LPA at all, start with the parent guide How to Choose a CPA in Canada — 2026 Buyer’s Guide and the decision framework in Compilation vs Review vs Audit — Decision Guide.

Compliance note. This guide follows CPA Ontario’s Code of Professional Conduct, including Rule 217 (advertising and solicitation) and Rule 401 (practice names). We do not identify or compare named competitor firms. We teach the selection criteria and let you evaluate any LPA — including us — against them.

The seven criteria to shortlist any LPA in Ontario

Use these as a checklist. Any LPA you engage in 2026 should meet every item without hesitation.

1. Verify the Public Accounting Licence on the CPA Ontario PAL directory

Ontario is unusual in that the public accounting licence is separately searchable from the general CPA member directory. Go to the CPA Ontario Public Accounting Licence Directory and search by the practitioner’s name or firm. A live, current entry confirms the licensee is authorized to sign assurance work today. If nothing comes up — or the entry is inactive — the person cannot legally sign your audit or review report, regardless of what their business card says. This is a one-minute check that eliminates the majority of upstream risk.

2. Confirm CPA Ontario firm registration

Firms themselves are not licensed under Ontario’s regime — only individual practitioners hold the PAL. However, firms that engage in public accounting must register with CPA Ontario and must have a lead engagement person who holds an active PAL. Confirm the firm you are shortlisting is on the CPA Ontario firm directory and that the practitioner you will be dealing with is the registered lead engagement person for your file. See CPA Ontario’s Public Accounting Licence overview.

3. Confirm professional liability insurance meets the minimums

As a condition of licensure, firms engaging in public accounting in Ontario must maintain professional liability insurance with minimum limits of $1,000,000 per claim and $2,000,000 in the aggregate. Ask for confirmation in the engagement letter. Larger firms often carry substantially higher coverage — $5M/$10M or more — which becomes relevant when your business’s assets or the potential loss on a misstated engagement exceed the statutory minimum.

4. Ask about practice inspection history

Every Ontario firm engaged in public accounting is subject to CPA Ontario’s Practice Inspection Program, which visits each firm on a minimum three-year cycle and more often where risk factors warrant. Ask when the firm was last inspected and what the outcome was. An LPA firm that has completed multiple inspection cycles with satisfactory ratings is demonstrating sustained quality. A firm that cannot describe its inspection history is either very new or evading a difficult question.

5. Match the LPA’s assurance-work volume to your engagement type

Not every LPA does audits. Not every LPA does reviews. Many LPAs qualified through an Approved Training Office earlier in their career and now practise primarily on compilations and tax, only occasionally signing a review. The practical experience requirements under CPA Ontario Regulation 17-1 include a minimum of 2,500 chargeable hours in public accounting, of which at least 1,250 must be in assurance, at least 625 in audit of historical financial information, and at least 100 in review procedures — but qualifying once does not oblige a practitioner to do that volume every year. Ask the LPA specifically: how many audits did you sign last year, and how many reviews? If your engagement is an audit and their last one was three years ago, keep shopping.

6. Match industry-specific experience to your file

An LPA who audits condominium corporations weekly is not the same person as an LPA who audits registered charities. Both hold the same licence. Both are equally authorized to sign. But the depth of familiarity with the specific standards — ONCA disclosures for NPOs, the Condominium Act, 1998 section 60 audit requirement for condo corps, MFDA rules for mortgage brokerages, Ministry of Colleges and Universities requirements for career colleges — comes from repetition, not from the licence itself. Ask for a count of prior engagements in your specific industry.

7. Confirm succession and business-continuity plan

The LPA cohort in Ontario is small and ageing on average. If you are entering a multi-year engagement (a condo corp, an NPO, a franchise reporting relationship), ask what happens to your file if the signing partner retires, becomes ill, or leaves the firm. Solo LPAs should have a written business-continuity arrangement with another licensed practitioner. Firms with two or more LPAs should be able to name the alternate partner assigned to your file.

What to ask any LPA — the 8-question shortlisting interview

Take these questions verbatim into a 30-minute call. Interview two or three LPAs. Compare answers side by side.

1. What is your CPA Ontario member number, and can I search you on the PAL directory right now?
2. How many audit engagements did you sign last year? How many review engagements? How many third-party-reliant compilations?
3. How many clients do you currently serve in my specific industry / sector (condo corporations, non-profits, credit unions, mortgage brokerages, career colleges, franchise financials, other)?
4. When was your firm’s most recent CPA Ontario Practice Inspection, and what was the outcome — no findings, minor findings, or a required remediation?
5. What are the limits and expiry date on your firm’s professional liability insurance?
6. Who is my lead engagement partner, who signs the report, and who is the backup partner if you are unavailable?
7. Will you provide a written engagement letter that specifies the standard (CAS for audit, CSRE 2400 for review, CSRS 4200 for compilation), the deliverables, the fee, and the independence declaration?
8. What is your quoted fee for my engagement, and what triggers a fee re-quote?

Bader A. Chowdry, CPA, CA, LPA answers these on the first discovery call for any Insight Accounting CPA prospect. Any well-run LPA firm should be able to do the same.

Regular CPA vs LPA — what actually differs

Both hold the CPA designation. Both are members of CPA Ontario. Both are bound by the CPA Code of Professional Conduct. The differences are narrow but consequential.

Category	Regular CPA (no PAL)	Licensed Public Accountant (LPA)
Authority to sign audit reports (CAS) in Ontario	No	Yes
Authority to sign review engagement reports (CSRE 2400) in Ontario	No	Yes
Authority to sign compilation reports with third-party reliance (CSRS 4200)	No	Yes
Authority to sign compilation reports with no third-party reliance	Yes	Yes
Authority to file T1 and T2 returns and provide tax advisory	Yes	Yes
Authority to provide bookkeeping and monthly-close services	Yes	Yes
Governing statute for licensure	CPA Ontario Act, 2017	CPA Ontario Act, 2017 + Public Accounting Act, 2004
Practice inspection frequency	Cycle depends on services offered	Minimum every three years
Professional liability insurance minimum	Firm-set	$1M per claim / $2M aggregate as licensing condition
Population in Ontario (2026)	~100,000 CPA Ontario members	~250 practising LPAs
Practical experience requirement	CPA PEP + 30 months practical	+ 2,500 hours public accounting (1,250 assurance / 625 audit / 100 review)
Approved Training Office pathway	Not required	Required for direct PAL path; PDPA alternative for non-ATO experience

The table makes the point compactly: for tax, planning, bookkeeping, and internal management reporting, a regular CPA is fully qualified. The LPA licence only becomes necessary when the deliverable is an assurance report — or a compilation that a stakeholder outside management will rely on.

When you do NOT need an LPA (and a regular CPA is fine)

The LPA cohort’s scarcity means the fees for LPA-led engagements run higher than for equivalent non-assurance work at a generalist CPA firm. If your engagement does not require assurance, hiring an LPA firm just for tax and bookkeeping is over-buying. A regular CPA — or an LPA firm delivering non-assurance work at the appropriate rate — is the right fit for:

• Personal T1 preparation.
• Corporate T2 preparation where the corporation does not need audited or reviewed financial statements for a stakeholder.
• Bookkeeping and monthly close where the deliverable stays internal.
• Compilations (CSRS 4200) that will not be relied on by any third party, with the report expressly stating no assurance is provided.
• Tax planning, remuneration planning, retirement planning, and succession planning.
• Advisory, business valuation for internal use, incorporation strategy, TOSI planning.
• HST, payroll, and slip filings (T4, T5, T5018).

Common LPA-required situations in Ontario

If you are here, you probably arrived through one of these triggers:

• Condo corporations. The Condominium Act, 1998 section 60 requires an audit for most condominium corporations, with limited exceptions for smaller corporations that pass a unanimous owner waiver. Only an LPA can sign that audit. For a full walk-through, see How to Choose a CPA for Your Condo Corporation (Ontario 2026).
• Non-profit organizations and charities. The Ontario Not-for-Profit Corporations Act, 2010 (ONCA) sets audit and review thresholds based on annual revenue and member type; larger NPOs generally require audit, mid-size may allow review by member vote, and only the smallest can rely on compilation. Boards should confirm the current threshold with counsel.
• Credit unions. The Credit Unions and Caisses Populaires Act, 2020 requires an annual audit by an appointed public accountant.
• Mortgage brokerages. The Financial Services Regulatory Authority of Ontario (FSRA) requires audited annual financial statements for licensed mortgage brokerages under the Mortgage Brokerages, Lenders and Administrators Act, 2006.
• Career colleges. Ontario’s private career colleges submit audited financial statements to the Ministry of Colleges and Universities annually as a condition of registration.
• Franchise disclosure documents. The Arthur Wishart Act (Franchise Disclosure), 2000 requires that financial statements attached to a franchise disclosure document be audited or reviewed unless a specific exemption applies.
• Bank covenant financial statements. Term loans, operating lines, and mortgage renewals often trigger review or audit requirements above certain principal thresholds.
• Acquisition-side due diligence. Buyers of privately held businesses commonly require review or audit-quality financials from the vendor as a closing condition.

Each of these is a legal or contractual requirement, not a preference. Hiring a non-LPA to save fees does not satisfy the requirement — it usually costs more once the report is rejected and the work is redone by a licensed practitioner.

Red flags — signs an LPA relationship will end badly

Red flag 1 — A CPA who is not an LPA offering to sign your audit or review report. This is the biggest single flag in the sector. If a CPA volunteers to sign your audit and cannot produce a live entry on the CPA Ontario PAL directory, walk away and report the offer to CPA Ontario. This is a violation of the Public Accounting Act, 2004.

Red flag 2 — Refusal to provide a written engagement letter. Every assurance engagement — CAS audit, CSRE 2400 review, CSRS 4200 compilation — requires a written engagement letter under the applicable CPA Canada Handbook standard. No exceptions.

Red flag 3 — Evasion on practice inspection. An LPA who cannot or will not describe the outcome of the firm’s most recent CPA Ontario Practice Inspection is signalling either that the firm has never been inspected (rare and worth investigating) or that the outcome was not favourable.

Red flag 4 — No independence declaration. Assurance engagements require the LPA to be independent of the client in fact and in appearance. If the same practitioner also provides bookkeeping, tax planning, or advisory to the client, the firm must apply threats-and-safeguards analysis to preserve independence. An LPA who waves off the question has not thought about it.

Red flag 5 — Sole practitioner with no continuity plan. A solo LPA offering a five-year condo-audit relationship without a written succession arrangement is a bet on one person’s health and career choices. Ask for the plan in writing.

Red flag 6 — Under-insured firm. Any firm that cannot produce evidence of at least the $1M / $2M professional liability minimums is either mid-renewal (fine, ask for the renewal date) or non-compliant with a condition of licensure (walk away).

FAQ — Choosing an LPA in Ontario, 2026

Q: What is the difference between an LPA and a CPA in Ontario?

All LPAs are CPAs, but only a small fraction of CPAs — approximately 250 out of 100,000+ CPA Ontario members in 2026 — hold the Public Accounting Licence that authorizes them to sign audit reports, review engagement reports, and third-party-reliant compilation reports under Ontario’s Public Accounting Act, 2004. A regular CPA can file your taxes, run your bookkeeping, and advise you on planning matters. An LPA can additionally sign assurance work.

Q: How do I verify that someone is a Licensed Public Accountant in Ontario?

Search the free public CPA Ontario Public Accounting Licence Directory by name or firm. A current, active entry confirms the individual is licensed to sign assurance work today. If nothing comes up, the person is not licensed regardless of their marketing materials.

Q: Who can sign an audit report in Ontario?

Only a Licensed Public Accountant (LPA) — a CPA who additionally holds a valid Public Accounting Licence issued by CPA Ontario under Regulation 17-1 and the Public Accounting Act, 2004. See CPA Ontario’s When is a PAL Required and the PAA 2004 on CanLII.

Q: How often is an LPA firm inspected in Ontario?

CPA Ontario’s Practice Inspection Program visits each firm engaged in public accounting on a minimum three-year cycle, with more frequent inspections where risk factors warrant. See the Practice Inspection General Information page.

Q: What professional liability insurance must an LPA firm carry?

As a condition of licensure, firms engaging in public accounting in Ontario maintain professional liability insurance with minimum limits of $1,000,000 per claim and $2,000,000 in the aggregate. Many firms carry higher limits voluntarily.

Q: What happened to the Public Accountants Council for the Province of Ontario (PAC)?

The Public Accountants Council for the Province of Ontario, which historically supervised the public accounting profession under a three-designation regime, was dissolved on April 30, 2021. Since that date, CPA Ontario holds all regulatory oversight for public accounting in the province, administered through the Public Accounting Standards Committee (PASC) and the Public Accounting Licensing Board (PALB). See CPA Ontario’s governance page on PAC.

Q: How does someone become an LPA in Ontario?

Three requirements under CPA Ontario Regulation 17-1: (1) hold the CPA designation via the Common Final Examination (CFE) and the CPA Professional Education Program; (2) complete 30 months of qualifying practical experience, including 2,500 chargeable hours in public accounting, of which at least 1,250 must be in assurance, 625 in audit of historical financial information, and 100 in review procedures; (3) complete the practical experience in a CPA Ontario Approved Training Office (ATO) under LPA supervision, or complete the Post-Designation Public Accounting Program (PDPA) if the experience was gained outside an ATO.

Q: Can a compilation engagement be signed by a non-LPA CPA?

Yes — but only if it is a “no third-party reliance” compilation. If the compilation report will be relied on by a bank, buyer, franchisor, regulator, or any external stakeholder, the Public Accounting Act, 2004 treats it as public accounting work and requires an LPA. In practice, most compilations produced for owner-managed corporations today involve at least one stakeholder that will read them, which pushes the engagement into LPA territory. Ask the CPA to document the “no reliance” assumption in writing if they are performing the work without an LPA.

A composite example — how a Mississauga condo board shortlisted an LPA

A 96-unit condominium corporation in Mississauga was preparing to change auditors after ten years with the same firm. The treasurer built a shortlist by:

1. Pulling the PAL directory and filtering for LPAs based within 25 km of the property. Result: 34 practitioners.
2. Emailing each with three questions: how many condo corporation audits did you sign in 2025, when was your last practice inspection, and what is your fee band for a corporation of our size? Result: 11 substantive replies.
3. Filtering to LPAs with at least 6 condo audits signed in 2025 (adequate specialization depth). Result: 5 shortlisted.
4. Meeting the top three for a 30-minute call using the 8-question interview from above.
5. Selecting the firm that produced a written engagement letter within 48 hours of the call, referenced CAS 700 in the report format sample, and offered the best-defined transition plan for taking working papers from the outgoing firm.

The whole process took the treasurer under six hours of active work. This is the standard against which to measure your own shortlisting effort. Insight Accounting CPA Professional Corporation — led by Bader A. Chowdry, CPA, CA, LPA — is one of the firms that fits this pattern for owner-managed businesses and community-scale organizations across the GTA. Any LPA firm that meets the same criteria serves you equally well.
