When your bank asks for "reviewed financial statements" or your accountant mentions a "Notice to Reader," it can be hard to know what level of financial statement service your business actually needs — or why the price difference is so significant. In Canada, there are three distinct levels of financial statement service, each governed by its own professional standards and carrying a different degree of assurance. Choosing the right one protects your business, satisfies lenders, and avoids paying for more than you need.
This guide breaks down compilations (Notice to Reader), review engagements, and audits so you can make an informed decision for your Alberta business.
Canadian accounting standards establish a clear hierarchy of assurance. At the bottom is the compilation, which provides no assurance at all. In the middle is the review engagement, which provides limited assurance. At the top is the audit, which provides the highest level of assurance available. The level you need depends on who will be relying on your financial statements and for what purpose.
A compilation, formally known as a Notice to Reader (NTR), is the most basic level of financial statement service. The accountant takes financial information provided by management — your trial balance, bank statements, invoices, payroll records — and assembles it into properly formatted financial statements. The accountant does not verify the accuracy of the information, does not test whether transactions actually occurred, and does not confirm balances with outside parties.
Because no verification is performed, a compilation provides no assurance whatsoever that the statements are free from material misstatement. The accountant is simply presenting the numbers you provided in a structured format that conforms to an applicable financial reporting framework.
Compilations in Canada are governed by Canadian Standard on Related Services (CSRS) 4200, which replaced the old Section 9200 in December 2021. The change was more significant than it might appear. Under CSRS 4200, management must now formally acknowledge their responsibility for the financial statements in writing — either through a separate engagement letter acknowledgment or a statement on the face of the financial statements themselves. This was a deliberate move by CPA Canada to reduce the risk of third parties over-relying on compiled statements, since compilations now carry an explicit notice that no assurance is provided and that users should be aware the statements may not be suitable for all purposes.
The updated standard also requires the accountant to include a description of the basis of accounting used and, in certain cases, to consider whether the statements are misleading on their face. While this does not add assurance, it does add transparency about what the compilation is — and what it is not.
Compilations are the most affordable option, typically ranging from $1,500 to $5,000 for most small and medium-sized businesses, depending on the complexity of your operations and the state of your bookkeeping. The vast majority of private small and medium-sized businesses in Canada rely on compiled financial statements for their annual CRA tax filings. If you are a private company with no external lenders requiring reviewed or audited statements, no outside investors with contractual rights to a higher level of assurance, and no regulatory obligations, a compilation is almost certainly all you need.
Typical users include owner-managed corporations, professional corporations, small retail businesses, and holding companies where the shareholders are also the managers and no one outside the business is relying on the statements for lending or investment decisions.
A review engagement is a step up in both rigour and cost. The accountant performs inquiry and analytical procedures — asking management pointed questions about significant transactions, comparing financial ratios to prior periods and industry norms, and investigating anything that appears inconsistent or unusual. Unlike an audit, the accountant does not independently verify balances by contacting your bank or confirming receivables with customers.
The result is negative assurance, expressed in standard language along the lines of: "Based on our review, nothing has come to our attention that causes us to believe the financial statements do not present fairly, in all material respects…" This is a subtle but meaningful distinction from audit language. The accountant is not saying the statements are correct — they are saying they did not find anything to suggest the statements are wrong.
Review engagements are governed by Canadian Standard on Review Engagements (CSRE) 2400. This standard sets out the procedures the accountant must perform, the level of professional judgement required, and the form of the review report. A CPA performing a review engagement must have a reasonable basis for concluding that nothing has come to their attention indicating a material misstatement, which is a higher bar than the compilation standard but substantially lower than audit requirements.
Review engagements typically cost between $5,000 and $15,000, again depending on the size and complexity of your business. The most common trigger for needing a review engagement is bank financing. Commercial lenders in Canada — particularly for loan amounts above $1 million to $2 million — routinely require reviewed financial statements as a condition of lending. From the bank's perspective, the review engagement provides a level of independent scrutiny that gives them confidence the numbers have not simply been fabricated or materially distorted.
Other situations where a review engagement may be required include shareholder agreements that specify a review as a condition of triggering buyout provisions, certain franchise agreements, and some government grant applications. If you are approaching your bank for a commercial mortgage, a line of credit expansion, or equipment financing at a meaningful scale, it is worth asking your lender directly what level of assurance they require before you engage your accountant — lender requirements vary.
Swift Accounting Calgary regularly assists owner-managed businesses and growing companies in preparing review engagement financial statements that satisfy commercial lender requirements across Alberta.
An audit is the most rigorous and comprehensive level of financial statement service available. The auditor independently gathers evidence to support the figures in the financial statements. This means confirming account balances directly with third parties — your bank, major customers, suppliers — testing a sample of transactions to verify they are properly recorded, evaluating internal controls to identify where errors or fraud are most likely, and performing substantive procedures designed to detect material misstatements whether caused by error or fraud.
The result is positive assurance: the auditor's report states that in their opinion, the financial statements present fairly, in all material respects, the financial position of the company in accordance with the applicable financial reporting framework (typically ASPE or IFRS in Canada). This is the strongest statement an accountant can make about a set of financial statements.
Audits in Canada are conducted in accordance with the Canadian Auditing Standards (CAS), which are closely aligned with International Standards on Auditing (ISA). The CAS framework is extensive and sets out detailed requirements for risk assessment, audit planning, evidence gathering, and reporting. Performing an audit requires significantly more time, documentation, and professional judgement than a review or compilation — which is why the cost difference is substantial.
Audits typically start at $15,000 and can exceed $50,000 for larger or more complex organizations. Most private small and medium-sized businesses do not need an audit and would find the cost difficult to justify. However, audits are mandatory or effectively required in several situations:
For most private Alberta companies, the audit requirement simply does not arise unless the business reaches significant scale, takes on institutional investment, or has specific contractual or regulatory obligations.
If you are a private owner-managed business filing your annual corporate tax return with CRA and have no external lenders or investors requiring more, a compilation is almost certainly appropriate. It is cost-effective, meets CRA requirements, and satisfies the reporting needs of most private companies.
If you are seeking commercial financing above roughly $1 million to $2 million, or if your shareholders' agreement or lender covenants specify reviewed statements, a review engagement is what you need. The additional cost is real but proportionate to the financing you are seeking.
If you are a public company, a Crown corporation, a charity or not-for-profit above relevant revenue thresholds, or a private company with specific contractual audit obligations, you will require a full audit.
When in doubt, the most practical step is to ask whoever is requesting the financial statements — your bank, your lawyer, your shareholders — exactly what standard they require. Swift Accounting provides compilations and review engagements for private businesses across Calgary and Alberta, and can help you determine which service fits your situation before you commit to an engagement.
For smaller loan amounts — typically under $500,000 to $1 million — many lenders will accept compiled financial statements. However, as the loan amount increases, most Canadian commercial lenders require reviewed or audited statements. The specific threshold varies by lender and loan product, so confirm directly with your bank before preparing your statements. Presenting compiled statements to a lender who requires reviewed ones can delay your financing and require you to start the process over.
CSRS 4200 replaced Section 9200 in December 2021 and introduced a formal requirement for management to acknowledge in writing their responsibility for the financial statements and the basis of accounting chosen. In practical terms, this means your accountant will ask you to sign an acknowledgment — either as part of the engagement letter or as a statement on the financial statements themselves. It does not change the level of assurance provided (which remains zero for a compilation), but it does create a clearer paper trail of responsibility. Most business owners notice little difference beyond the additional acknowledgment step.
It depends on the charity's gross revenue, its province of incorporation, and its own governing documents. Many charitable organizations are required to have audited financial statements once annual gross revenues exceed $250,000 or $500,000 — the threshold varies. Some charity bylaws require an audit regardless of revenue. Charities that receive provincial or federal government funding may face additional audit requirements as a condition of their grant agreements. If you operate a registered charity, review your incorporating documents and any funding agreements carefully, and consult a CPA to confirm your specific obligations.
A compilation can typically be completed within one to three weeks once all your financial records are in order. A review engagement generally takes three to six weeks, as the accountant needs time to perform analytical procedures and follow up on inquiries. An audit is the most time-intensive, often requiring six to twelve weeks or more depending on the size of the organization and the complexity of its transactions. Starting the process early — ideally within sixty days of your fiscal year-end — helps avoid delays and ensures your statements are available when lenders or regulators need them.
Whether you need a straightforward annual compilation for your corporate tax filing or a review engagement to satisfy your bank's lending requirements, having the right professional in your corner makes the process simpler.
