Acquiring a dental practice in Ontario is one of the most significant financial decisions a dentist will make. Most buyers understandably focus on production numbers, patient count, and the asking price — but the operational health of a clinic is often what determines whether an acquisition becomes a successful practice or an expensive problem.
Your accountant reviews the financials. Your lawyer reviews the contracts. But who evaluates whether the practice actually runs well? An independent operational audit fills that critical gap.
Patient Base Analysis
A large patient list doesn't automatically mean a valuable practice. What matters is how active and engaged those patients are.
Key metrics to evaluate:
- Active patient count: How many patients have been seen in the last 18 months? The total patient database is often 3–5 times larger than the active base.
- New patient trends: Look at monthly new patient numbers over the past 3 years. A declining trend signals problems the seller may not disclose.
- Hygiene recall rate: A healthy practice maintains 80% or higher. Below 60% indicates systemic issues with patient retention and reactivation.
- Patient demographics: Age distribution, insurance mix, and geographic spread all affect future revenue stability.
- Treatment acceptance rate: If patients are accepting less than 60% of recommended treatment, there may be trust, communication, or pricing issues.
Financial Deep Dive
Beyond top-line revenue, examine the financial systems that drive — or undermine — profitability.
- A/R aging: High receivables over 90 days indicate broken billing systems you'll inherit. See our guide on A/R recovery for benchmarks.
- Overhead breakdown: Staff costs, lab fees, supplies, and facility costs as a percentage of collections. Ontario dental practices should target 55–65% total overhead.
- Fee schedule analysis: Are fees competitive for the market area? Are they frequently discounted or written off?
- Insurance dependency: A practice that relies heavily on one or two insurance carriers is vulnerable to fee guide changes or plan terminations.
- Write-off patterns: High write-offs can indicate fee schedule problems, coding issues, or poor treatment planning.
Operational Assessment
This is where most due diligence processes fall short. The operational reality of a practice tells you how much work — and investment — will be needed post-acquisition.
- Staff retention: Request staff tenure data. High turnover, especially in admin roles, typically signals management or culture problems.
- Documented procedures: Does the clinic have a current operations manual? SOPs? Documented workflows? Lack of documentation means the practice runs on individual knowledge, which creates risk when ownership changes.
- Technology and equipment: Assess the age and condition of major equipment, digital imaging capabilities, and software systems. Deferred maintenance is a hidden cost.
- Scheduling efficiency: Review chair utilization rates, no-show rates, and scheduling patterns. Inefficient scheduling directly impacts production capacity.
Compliance Review
- IPAC compliance: When was the last IPAC audit? Are there outstanding deficiencies? An independent IPAC assessment should be part of any pre-purchase evaluation.
- RCDSO standing: Check for any complaints, practice reviews, or disciplinary history.
- Lease terms: Review the facility lease carefully — assignment clauses, renewal options, and escalation terms can significantly impact the deal's value.
- Employment compliance: Review employment contracts, non-compete clauses, and compliance with Ontario Employment Standards Act requirements.
Red Flags That Should Slow You Down
- Seller unwilling to provide detailed A/R aging reports or patient data
- Significant staff turnover in the 6–12 months before listing
- No documented processes, manuals, or SOPs
- Hygiene recall rate below 60%
- Significant deferred maintenance on clinical equipment
- Production heavily concentrated in one provider — the departing owner
- Declining new patient numbers over 12+ months
Practical Takeaways
- Don't rely solely on financial due diligence — the operational audit is equally important
- Request at least 3 years of data for trend analysis
- Evaluate the team as carefully as the patient base
- Factor compliance and remediation costs into your offer
- An independent third-party audit protects your investment
