What is a PA?

Physician Assistants (PAs) are healthcare professionals who work in collaboration with physicians and other healthcare providers to deliver patient care.

Rooted in the concept of team-based care, PAs work under the supervision of licensed physicians, but they possess the autonomy to perform a wide range of clinical tasks and procedures.

PA Education

PA programs are offered programs typically last two years and combine didactic instruction with hands-on clinical training to create a well-rounded and competent healthcare professional.

PA School Year 1 (PA-S1)

1st year of PA school consists of didactic, classroom learning supplemented with hands-on clinical skills where students learn medical foundations. There is also early exposure to health care through clinical placements in the first year. This comprehensive curriculum covers essential medical sciences, clinical medicine, pharmacology, ethics, and patient communication. Students learn to perform physical examinations, interpret diagnostic tests, and develop clinical reasoning skills.

PA School Year 2 (PA-S2)

2nd year of PA school consists of clinical placements in core and elective rotations. Students gain practical experience in various medical specialties including Family Medicine, Emergency Medicine, Internal Medicine, Psychiatry, Geriatrics, Women’s Health, Paediatrics, Surgery and more. These rotations take place in hospitals, clinics, and other healthcare settings, where students work alongside healthcare professionals to apply their knowledge in real-world scenarios.

During their clinical rotations, PA students are assigned preceptors who are experienced healthcare providers. Under their guidance, students develop practical skills, enhance clinical decision-making, and gain exposure to different patient populations.

Becoming PA Certified

In Canada, Physician Assistants (PAs) are certified through the Physician Assistant Certification Council of Canada (PACCC). This certification is essential for PAs to practice in Canada and demonstrates that they meet the national standards for competency and practice in the profession

  • Candidates must graduate from a Physician Assistant program that is accredited by the Canadian Medical Association’s Conjoint Accreditation Services (or an equivalent recognized by PACCC). In Canada, there are a few key programs, such as those offered by:

    • After completing the PA program, graduates must pass the PA Certification Examination (PACE) administered by PACCC. This exam is typically offered once a year and tests the candidate's knowledge and skills across various areas of medical practice.

    • The exam is comprehensive, covering topics like clinical medicine, diagnostics, therapeutics, and professional practice.

  • Upon passing the certification exam, candidates are awarded the Canadian Certified Physician Assistant (CCPA) designation. This credential signifies that the individual has met the national standards for entry-level PA practice in Canada.

    • Continuing Professional Development (CPD): CCPAs must participate in ongoing professional development to maintain their certification. This includes completing a minimum of 40 CPD credits every two years.

    • Certification Renewal: The CCPA designation must be renewed every five years, which includes demonstrating ongoing professional development and maintaining a current practice.

PA Scope of Practice

PA scope of practice in Canada encompasses a wide range of medical and clinical responsibilities, allowing provision of comprehensive and patient-centred care in collaboration with a supervising physician.

  • Item description
  • PAs have the authority to order and interpret various investigations, such as blood tests, imaging (x-rays, CT scan, MRI, ultrasound, etc.) and other diagnostic procedures, which aids in the timely diagnosis and treatment of patients.

    • Physician Assistants excel in clinical reasoning and are skilled at formulating comprehensive differential diagnoses. They analyze patient data, interpret test results, and collaborate with physicians to arrive at accurate and timely diagnoses, which is crucial for initiating appropriate treatments promptly.

  • Under the guidance and supervision of a licensed physician, PAs are authorized to prescribe medications to patients.

    This includes both ongoing prescriptions for chronic conditions and short-term medications for acute illnesses.

  •  Physician Assistants are trained to perform medical procedures and interventions.

    These may include suturing wounds, administering injections, lumbar punctures, casting and reduction of fractures, joint injections, removing sutures or staples, and providing wound care.

  • PAs may assist in surgical procedures, working closely with surgeons and other surgical team members to ensure smooth and safe operations.

  • PAs may have on-call or pager responsibilities, responding to urgent medical situations and providing timely medical advice and intervention.

Specialties That Employs PAs

One of the key strengths of Physician Assistants lies in their ability to work across a wide range of medical specialties, making them valuable assets in various healthcare settings.

Scope of practice reflects the supervising physician they work with.

  • Physician Assistants are known for their flexibility and versatility in clinical practice. Trained as generalists, PAs can work across a wide range of specialties—from emergency medicine and orthopaedics to dermatology and psychiatry. With the ability to transition between disciplines without retraining, PAs bring adaptable, team-based care to wherever patients need them most

    • Family Medicine

    • Emergency Medicine

    • Surgery

    • Pediatrics

    • Internal Medicine

    • Orthopaedic Surgery

    • Dermatology

    • Psychiatry

    • Cardiology

    • Oncology

    • Geriatrics

    • Obstetrics and Gynecology (OB/GYN)

    • Nephrology

    • Neurology

    • Endocrinology

    • Urology

    • Pulmonology

    • Gastroenterology

    • Infectious Disease

    • Rheumatology

    • Hematology

    • Pain Management

    • Occupational Medicine

    • Physical Medicine and Rehabilitation (PM&R)

    • Radiology

    • Plastic Surgery

    • ENT (Ear, Nose, and Throat)

    • Allergy and Immunology

    • Sports Medicine

    • Palliative Care/Hospice

  • Lateral Mobility

    Lateral mobility refers to the ability of Physician Assistants (PAs) to move between different medical specialties during their careers. Unlike some healthcare professionals who are often trained and restricted to a single specialty, PAs have the flexibility to switch fields without needing to undergo entirely new formal education.

    This is because PAs are trained in a broad, general medical model that equips them with the foundational knowledge and skills to work in various areas of medicine. For example, a PA who starts their career in emergency medicine could later transition to dermatology or orthopaedics with additional on-the-job training and experience.

    This flexibility is a significant advantage of the PA profession, allowing PAs to pursue different interests and respond to changing healthcare needs throughout their careers.

PA Practice in Canada

Each province is at a different stage in integrating and regulating PAs, reflecting varied approaches to addressing healthcare system demands and workforce challenges.

The Canadian Association of Physician Assistants continues with efforts to expand the scope and recognition of PAs, with legislative changes, and the introduction of PAs in more provinces and territories.
