Medical Clinic Overhead in Ontario: What Physicians Should Actually Look For Before Joining a Clinic

When physicians look to join a clinic in Ontario, one of the first things they focus on is overhead. Naturally, a lower percentage seems more attractive. But in practice, overhead is one of the most misunderstood aspects of joining a clinic. Focusing only on the percentage can lead to the wrong decision. What matters is not just how much you are paying, but what you are getting in return.

What is typical overhead in Ontario

Most clinics in Ontario fall within a fairly consistent range.

competitive clinics are typically in the 20% to 25% range
more established or higher-cost clinics can be closer to 25% to 30%

With more physicians entering the market and more clinics opening, overhead has become increasingly competitive. That said, anything significantly below 20% should be approached with caution. At that level, it becomes difficult for a clinic to properly cover its costs while still providing a strong level of support.

Why lower overhead does not always mean more money

This is one of the most important points. A lower overhead percentage does not automatically mean higher take-home income. In many cases, the opposite is true.

For example:

a clinic offering 15% overhead but with poor systems, limited staff, and low patient flow may result in lower overall earnings
a well-run clinic at 25% overhead with strong patient volume, efficient workflows, and proper support can lead to significantly higher income

The difference comes down to how the clinic operates.

How staffing structure impacts your overhead

One of the biggest drivers of overhead in any clinic is staffing. In most cases, staffing is the single largest ongoing cost, and it has a direct impact on both the overhead percentage and your day-to-day experience as a physician. Clinics can vary significantly in how they structure their teams.

Some clinics operate with:

basic front desk coverage only
minimal clinical support

Others invest more heavily in:

experienced MOAs who can handle both administrative and clinical tasks
nurses on-site to support patient care
physician assistants where applicable
dedicated clinic managers

This difference in staffing structure directly affects overhead.

Why staffing matters for physicians

A clinic with stronger staffing support may have slightly higher overhead, but it often allows you to:

see more patients efficiently
reduce administrative burden
focus more on clinical care
avoid taking work home

For example:

an advanced MOA who can assist with patient prep, flow, and basic clinical support can significantly improve efficiency
on-site nursing support can reduce bottlenecks and improve patient throughput
structured teams create a smoother, more predictable workflow

The trade-off between cost and support

Lower overhead clinics often achieve that by reducing staffing and operational support. This can result in:

fewer support staff
limited clinical assistance
more responsibility falling on the physician
slower patient flow

In contrast, clinics with more comprehensive staffing models tend to:

operate more efficiently
support higher patient volumes
provide a better overall working environment

What you are actually paying for

Overhead is not just a fee. It reflects the structure and quality of the clinic. A well-run clinic typically provides:

strong patient volume
efficient scheduling and workflow
experienced staff and support
proper billing support
management oversight
a well-designed space and layout
a good location that drives demand

All of these directly impact how many patients you see, how efficiently you work, and how much you ultimately earn.

The risks of very low overhead clinics

Clinics offering very low overhead often come with trade-offs.

These can include:

limited staff support
inefficient workflows
lower patient volume
increased administrative burden on physicians
inconsistent operations

In some cases, these clinics are not structured to sustain long-term operations at those rates. Over time, this can lead to:

increases in overhead
operational instability
frustration for physicians

Pharmacy-owned clinic models: what to be aware of

Some clinics, particularly those tied to pharmacies, may offer lower overhead to attract physicians. While this can seem appealing initially, there are important considerations. Pharmacies are experts in running pharmacies, but not always in running medical clinics. In some cases, this can result in:

weaker clinic management
less efficient operations
lack of proper physician support

There may also be an unspoken expectation around prescription volume. If those expectations are not met, we have seen situations where:

overhead structures are revisited
terms are renegotiated
relationships become strained

This does not apply to every model, but it is something physicians should be aware of when evaluating options.

The importance of physician-led and well-managed clinics

Clinics that perform well over time tend to have:

strong leadership
clear structure
experienced management
well-trained staff
efficient systems

Physician-led clinics, or clinics with a dedicated management team, are typically better positioned to support doctors properly. These clinics are more likely to:

maintain consistent patient volume
provide operational stability
support long-term growth

Billing support matters more than most realize

Another key factor that often gets overlooked is billing support. OHIP billing is complex, and small mistakes can lead to lost revenue. Clinics that provide:

experienced billing teams
dedicated billing agents
oversight and review

help ensure that physicians are not leaving money on the table. In many cases, strong billing support can have a greater impact on income than a few percentage points in overhead.

What physicians should actually look for

When evaluating a clinic, overhead should be one part of a larger picture. Key factors to consider include:

patient volume and demand
clinic location
workflow and efficiency
staffing structure and support
management and leadership
billing support
overall stability of the clinic

The goal is to find a clinic that allows you to work efficiently, see patients consistently, and minimize unnecessary stress.

Final thoughts

Overhead is important, but it should not be the only factor driving your decision. The difference between a good clinic and a poor one is not just the percentage you pay. It is how the clinic is structured, managed, and operated. In many cases, a slightly higher overhead at a well-run clinic results in better income, better support, and a much better overall experience. The best approach is to look at the full picture, not just the number.
