Incorporating is a common step for physicians who are building or joining a medical clinic.


It can provide tax planning opportunities, create a more formal business structure, and support long-term growth.


However, incorporating a medical practice in Ontario involves more than simply setting up a corporation.


There are specific regulatory requirements and structural considerations that must be addressed.



What Is a Medical Professional Corporation


Physicians in Ontario typically incorporate through a professional corporation.


This is different from a standard business corporation.


A professional corporation:


• is owned by a licensed physician

• is used to provide medical services

• must comply with the requirements of the College of Physicians and Surgeons of Ontario


The corporation cannot operate without meeting these requirements.


Key Requirements for Incorporation


1. Certificate of Authorization


Before a professional corporation can provide medical services, it must obtain a Certificate of Authorization from the College.


This process typically involves:


• submitting an application

• providing corporate documents

• confirming that the physician is licensed


Without this approval, the corporation cannot practice medicine.


2. Shareholder Restrictions


Professional corporations have strict ownership rules.


Generally:


• all voting shares must be owned by a licensed physician

• non-voting shares may be issued in limited circumstances, subject to regulatory rules


These restrictions are important when structuring ownership.


3. Naming Requirements


The name of the professional corporation must comply with specific rules.


This usually includes:


• the physician’s name as registered with the College

• the words “Professional Corporation”

• reference to the profession


Improper naming can delay approval.


4. Corporate Structure


Incorporation involves more than filing articles.


A proper structure includes:


• share structure planning

• director and officer appointments

• maintaining a corporate minute book


This ensures the corporation operates correctly.


How Incorporation Fits Into a Medical Clinic


In many clinics, physicians operate through their own professional corporations.


At the same time, the clinic itself may operate through a separate entity that:


• manages facilities

• employs staff

• provides administrative services


These entities must work together.


Key Considerations When Incorporating


1. Alignment With Clinic Agreements


The professional corporation must align with:


• physician agreements

• revenue-sharing structures

• overhead arrangements


If these are not aligned, issues may arise.


2. Billing and Revenue Flow


Physicians must consider:


• how billing is handled

• how funds flow through the corporation

• how income is structured


3. Tax Planning Considerations


Incorporation may offer tax planning opportunities, but:


• the benefits depend on individual circumstances

• proper structuring is required


Coordination with accounting advice is important.


4. Future Growth


The structure should allow for:


• joining or leaving clinics

• expanding services

• changes in practice


Planning ahead avoids restructuring later.


Common Mistakes When Incorporating


1. Treating It Like a Standard Corporation


Professional corporations have specific rules.


Using a generic incorporation approach can lead to compliance issues.


2. Not Aligning With Clinic Structure


If the corporation does not align with how the clinic operates:


• agreements may conflict

• operational issues may arise


3. Overlooking Regulatory Requirements


Failure to meet College requirements can result in:


• delays

• inability to practice through the corporation


4. Not Planning Beyond Incorporation


Incorporation is only the first step.


Without proper agreements and structure, issues can still arise.


Why This Matters for Physicians


Incorporation is often a key step in building a medical practice.


Done properly, it supports:


• long-term growth

• operational clarity

• risk management


Done improperly, it can create unnecessary complexity.
