When it comes to having a business in Canada, it means dealing with constant financial scrutiny, for sure. Lenders, investors, and regulators all expect your numbers to be accurate and credible. To meet those expectations, companies turn to assurance services,such as audits, review engagements, or compilations, performed by Chartered Professional Accountants (CPAs).
However, the thing is that choosing the wrong type of engagement can cost your business far more than you might expect. A lot of private corporations file incorrect or insufficient reports each year, leading to rejected loansand costly rework. In some cases, it even damages their reputation with stakeholders.
So, the real question is that how do you know what level of assurance your business needs, and what happens if you choose the wrong one? Let’s break it down clearly and practically.
The Three Levels of Assurance
Before understanding the risks, let’s look at the three main types of assurance engagements under Canadian corporate accounting standards:
1. Compilation (Notice to Reader):
The lowest level of assurance. The CPA simply compiles financial information provided by management without verifying its accuracy. It’s useful for internal use but typically not accepted by lenders or investors, because it does not verify the reliability of the financial statements.
2. Review Engagement:
Provides limited assurance. The CPA uses analytical procedures and management inquiries to assess if financial statements are plausible. It’s suitable for small or mid-sized companies needing moderate verification.
3. Audit Engagement:
Offers the highest level of assurance. The CPA tests transactions, confirms balances, and examines internal controls. It’s ideal for large corporations, public entities, or organizations with legal or funding obligations.
Each type of engagement has a cost and purpose. The right one gives confidence and compliance. The wrong one creates risk and that’s where the financial consequences begin.

When You Choose Less Assurance Than Needed
Let’s say your company applies for a loan, but you only submit compiled statements. The bank rejects them because they lack assurance. You now have to upgrade to a review or audit engagement, which means extra fees, lost time, and potential damage to credibility.
This is a common issue among small businesses trying to save money on accounting services for Canadian businesses. But skipping proper assurance can lead to:
· Lower Financing Costs: When there’s an assurance performed, most financial institutions provide funds at lower interest rates. So, without proper assurance, organizations lose their ability to raise funds at a lower cost.
· Grant Delays: Government programs often demand audited or reviewed financials. Without them, funding applications may be denied.
· Investor Concerns: Unaudited reports may act as obstacles to get easy funds from investors , limiting future funding opportunities.
In short, under-assurance can seem like a cost-saving move at first, but it often results in greater financial losses down the line.

When You Choose More Assurance Than Needed
On the flip side, some organizations go for full audits when they only need a review engagement. While it might look more professional, it’s often an unnecessary expense.
For instance, a non-profit earning under $500,000 in Ontario can choose a review instead of an audit under provincial law. Opting for an audit when not required could double accounting costs without any added benefit.
Over-assurance can lead to:
· Unnecessary Costs: Audits are more detailed and time-consuming, often costing thousands more than reviews.
· Longer Turnaround Times: Audits require extensive document checks, delaying reporting deadlines.
· Resource Strain: Small teams may struggle to gather all the required evidence for an audit that isn’t legally needed.
This doesn’t mean audits aren’t valuable,because they are, for sure. However, selecting one without assessing your organization’s needs and obligations is like buying insurance for risks you don’t face.
