Best CPAs for Compilation Report (Notice to Reader) in Ontario
A compilation engagement report—still widely known by its former name, Notice to Reader (NTR)—is the most common financial statement deliverable for Ontario private corporations. Since December 14, 2021, compilations are governed by CSRS 4200, which replaced the old Section 9200 standard and introduced new requirements around the basis of accounting, management acknowledgement, and a mandatory compilation engagement report. Most banks, lenders, leasing companies, and the CRA accept compiled financial statements for owner-managed businesses that do not require a review or audit, making the compilation report the practical, affordable choice for the vast majority of Ontario corporations. Whether you need year-end statements for your corporate tax return, financials to support a business loan or line of credit, statements for a shareholder buy-in, or simply clean numbers to understand your business, choosing the right CPA for your compilation engagement matters. The best compilation CPAs combine CSRS 4200 technical compliance, accurate underlying bookkeeping, a clear basis of accounting note, fast turnaround, transparent flat-fee pricing, and financial statements that lenders and the CRA accept without question. This guide highlights the top CPA firms in Ontario for compilation reports based on CSRS 4200 expertise, statement quality, turnaround speed, pricing transparency, and proven acceptance by banks and lenders. Each firm has been reviewed to help Ontario business owners find the right professional partner for accurate, compliant, cost-effective compilation engagements.

How much does a compilation report (Notice to Reader) cost in Ontario?
| Service Type | Typical Cost Range |
|---|---|
| Compilation Report Only (Books Already Clean) | CAD 500 - CAD 1,200 |
| Compilation Report + Year-End Adjustments | CAD 1,000 - CAD 2,000 |
| Compilation + T2 Corporate Tax Return (Bundled) | CAD 1,500 - CAD 3,000 |
| Compilation + Bookkeeping Catch-Up (Per Year) | CAD 2,000 - CAD 4,500 |
| Compilation for Holding Company (Inactive) | CAD 500 - CAD 900 |
| Compilation for Lender / Bank Financing | CAD 1,000 - CAD 2,500 |
| Rush / Expedited Compilation (48-72 Hours) | CAD 1,500 - CAD 3,500 |
| Comparative Two-Year Compilation Statements | CAD 900 - CAD 1,800 |
Compilation report costs vary based on the cleanliness of underlying books, transaction volume, number of years required, and whether the engagement is bundled with corporate tax filing. Most owner-managed Ontario corporations with reasonably maintained books pay between CAD 500 and CAD 1,200 for the compilation itself, with bundled compilation-plus-T2 packages offering the best value. Costs rise when bookkeeping cleanup is required before statements can be compiled. Flat-fee firms quote the full amount upfront, while hourly firms can produce billing surprises. A compilation is far more affordable than a review engagement (CAD 5,000-15,000) or audit (CAD 15,000+), which is why most private corporations choose it.

Compilation Reports in Ontario: Essential Information
A compilation engagement is the most common and affordable financial statement service for Ontario private corporations. Understanding the key elements helps you choose the right CPA and the right level of service:
What a Compilation Report Is (CSRS 4200)
- A compilation engagement assembles financial information provided by management into financial statements, without providing any assurance.
- Since December 14, 2021, compilations follow CSRS 4200, which replaced the old Section 9200 "Notice to Reader" standard.
- The deliverable is a "compilation engagement report" attached to the statements, replacing the former Notice to Reader wording.
- The statements must disclose the basis of accounting used (for example, historical cost), and management must acknowledge responsibility for the information.
Compilation vs Review vs Audit
- Compilation: no assurance, lowest cost (CAD 500-1,200 typical), accepted by most lenders and the CRA for owner-managed corporations.
- Review engagement: limited assurance, moderate cost (CAD 5,000-15,000), required by some lenders or shareholders.
- Audit: reasonable assurance, highest cost (CAD 15,000+), required for public companies, many not-for-profits, and certain large or regulated entities.
- Most private Ontario corporations need only a compilation unless a lender, shareholder agreement, or regulator specifically requires more.
When You Need a Compilation Report
- Year-end financial statements to support your T2 corporate tax return.
- Financials requested by a bank, leasing company, or lender for financing or a line of credit.
- Statements for a shareholder buy-in, share sale, or partner reporting.
- Clean financial statements to understand your business performance and position.
What Affects the Cost and Timeline
- Cleanliness of underlying books: clean bookkeeping lowers cost; cleanup raises it.
- Transaction volume and complexity of the business.
- Number of years required and whether comparative statements are needed.
- Whether the compilation is bundled with the T2 corporate tax return (usually the best value).
What Lenders and the CRA Expect
- A properly worded CSRS 4200 compilation engagement report signed by a licensed CPA firm.
- A clearly disclosed basis of accounting note on the statements.
- Consistent, accurate figures that reconcile to the corporate tax return.
- Comparative figures where the lender or stakeholder requests two years.
How to Choose Your Compilation Report CPA
- Confirm CSRS 4200 Compliance – Ensure the firm issues a current compilation engagement report, not outdated Notice to Reader wording, with a disclosed basis of accounting.
- Check Lender Acceptance – Ask whether their compiled statements have been accepted by banks and leasing companies for clients like you.
- Ask About Turnaround – Confirm the timeline and whether rush service is available if you have a financing or filing deadline.
- Demand Flat-Fee Pricing – Get the full cost upfront, including any bookkeeping cleanup, with no hourly surprises.
- Bundle with T2 Where Possible – Compilation-plus-corporate-tax packages usually deliver the best overall value.
- Verify Bookkeeping Accuracy – The compilation is only as good as the underlying books; confirm how they handle adjustments and reconciliations.
- Confirm CPA Licensing – Only a licensed CPA firm can issue a compilation engagement report; verify the designation.
- Assess Accessibility – Extended hours and a directly reachable lead CPA matter when deadlines are tight.
- Right-Size the Engagement – Make sure you are not being pushed toward a costly review or audit you do not actually need.
- Compare Two or Three Quotes – Request flat-fee proposals so you can compare value, not just headline price.

Governed today by CSRS 4200, a compilation delivers clean, professional financial statements that support your corporate tax return and satisfy most lenders and the CRA—without the cost of a review or audit.
