What Can a Nurse Practitioner Do? Full Scope of Practice in Ontario

What Is a Nurse Practitioner, Exactly?

A Nurse Practitioner is a registered nurse who has completed advanced graduate-level education, typically a Master's degree, and holds an expanded scope of practice that authorizes them to assess patients, diagnose conditions, order and interpret tests, and prescribe medications. In Ontario, NPs are regulated by the College of Nurses of Ontario and must meet rigorous clinical requirements before they can practise independently. They aren't physician assistants. They aren't nurses who "do a little extra." They're autonomous healthcare providers with full authority to manage your care.

The NP role has existed in Canada since the 1960s, but Ontario formalized the Nurse Practitioner title in 1998. Since then, the profession has expanded significantly, and NPs now work across every care setting you can think of: hospitals, community health centres, long-term care homes, mental health clinics, and yes, family practice. In fact, NP-led clinics have become an increasingly important part of Ontario's strategy to address the family doctor shortage, especially in cities like Toronto where waitlists for a physician can stretch for years.

What makes the NP model particularly well-suited to family practice is the emphasis on relationship-based care. NP training places a strong focus on health promotion, patient education, and treating the whole person rather than just the presenting complaint. When you see the same Nurse Practitioner every time you come in, they build a picture of your health that goes far beyond what's on a chart. That continuity is exactly what Care& Family Health was designed around.

The Full Scope of Practice for NPs in Ontario

The question "what can a Nurse Practitioner do?" has a surprisingly comprehensive answer. Under Ontario law, NPs in the primary care stream are authorized to perform a wide range of clinical activities independently, meaning they don't need a physician to co-sign or supervise their decisions. Here's what that includes:

• Performing comprehensive health assessments and physical examinations
• Diagnosing acute and chronic health conditions
• Ordering and interpreting diagnostic tests, including bloodwork, imaging (X-rays, ultrasounds, CT scans, MRIs), and ECGs
• Prescribing medications, including antibiotics, blood pressure medications, antidepressants, inhalers, and many others
• Performing minor clinical procedures such as wound care, suturing, incision and drainage, and removal of skin lesions
• Referring patients to specialists and hospital-based services
• Managing ongoing chronic conditions like diabetes, hypertension, asthma, and thyroid disease
• Providing preventive care including immunizations, screening tests, and well-baby visits
• Completing forms for insurance, disability, and workplace accommodation
• Ordering and interpreting screening tests such as Pap smears, STI panels, and prenatal bloodwork

That's not a partial list. For the vast majority of reasons you'd visit a family doctor, a Nurse Practitioner can provide the same care. The clinical scope is defined by the Nursing Act and expanded through regulations that have been updated multiple times over the past decade to give NPs even greater autonomy. Ontario has been a leader in this regard, and the 2024 changes to prescribing authority gave NPs access to an even broader range of medications.

There are a small number of things that fall outside an NP's current scope, such as prescribing certain controlled substances or performing complex surgical procedures. When those situations arise, your NP will refer you to the appropriate specialist. But for 80 to 90 percent of what happens in a family practice setting, an NP can handle it from start to finish. That seamless ability to assess, diagnose, treat, and follow up is exactly what makes the NP-led model work so well for ongoing primary care.

NP vs Doctor in Canada: What's the Difference?

This is one of the most common questions people ask, and it deserves a straightforward answer. Nurse Practitioners and physicians follow different educational paths but arrive at a very similar destination when it comes to family practice. Physicians complete medical school and a residency program. NPs complete a nursing degree, gain clinical experience as registered nurses, then complete a Master's-level NP program with extensive clinical placements. Both are trained to diagnose, treat, and manage health conditions independently.

The practical differences in a family practice setting are smaller than most people expect. Your NP can order the same bloodwork. They can prescribe the same classes of medications for common conditions. They can refer you to the same specialists. They can interpret your lab results and adjust your treatment plan. Where differences exist, they're typically at the edges of care. Physicians have a broader prescribing scope for certain controlled medications. They can perform more complex procedures. And in the hospital setting, the roles are more clearly divided.

But here's what matters most for your day-to-day healthcare: the quality of your relationship with your provider, the time they spend with you, and whether they actually know your history when you walk through the door. NP training places particular emphasis on patient education and collaborative decision-making. At Care& Family Health, each member is matched with a dedicated Nurse Practitioner who sees them at every visit. That means your provider isn't starting from scratch each time. They know your medications, your concerns, your family history, and your goals. To learn more about how this works in practice, visit How It Works.

When a Physician Is the Right Call

Your NP will be the first to tell you when you need to see a specialist or a physician for something outside their scope. If you need a complex surgical procedure, care for a rare condition that requires subspecialty management, or certain controlled medications, your NP will coordinate that referral. The key distinction is that your Nurse Practitioner remains your home base. They're the one who puts the pieces together, follows up after specialist visits, and makes sure nothing falls through the cracks. That quarterback role is arguably the most important one in your healthcare.

Can a Nurse Practitioner Prescribe Medication in Ontario?

Yes. Nurse Practitioners in Ontario have independent prescribing authority, and the list of what they can prescribe is extensive. If you need antibiotics for an infection, a statin for cholesterol, an antihypertensive for blood pressure, an antidepressant for mental health, an inhaler for asthma, or thyroid medication, your NP can prescribe it. They can also adjust dosages, switch medications if something isn't working, and manage the kind of ongoing prescription monitoring that's central to family practice.

Recent regulatory changes have continued to expand NP prescribing authority in Ontario. NPs can now prescribe a wider range of medications than ever before, and the gap between what an NP and a physician can prescribe in a primary care context has narrowed significantly. For the overwhelming majority of conditions managed in family practice, there's no prescribing limitation that would affect your care.

If you're pregnant, breastfeeding, or planning a pregnancy, your NP will take that into account before starting or adjusting any medication. The same goes for potential drug interactions. If you take multiple medications, your provider can review them together to ensure they're working safely in combination. Pediatric prescribing may also differ from adult dosing, so if you're bringing your child in, your NP will follow age-appropriate guidelines. Care& offers pediatric care as part of its family practice model, so children are welcome.

Chronic Disease Management and Preventive Care

If there's one area where the NP model truly shines, it's the management of chronic conditions. Diseases like type 2 diabetes, hypertension, asthma, COPD, hypothyroidism, and high cholesterol don't get better with a single appointment. They require regular monitoring, medication adjustments, lifestyle counselling, and lab work that tracks how your body is responding over time. This is exactly the kind of care that benefits from seeing the same provider at every visit.

Your Nurse Practitioner can order the A1C tests that track your blood sugar trends. They can adjust your blood pressure medication based on home readings and in-office measurements taken over months. They can order spirometry for your asthma and step your inhaler therapy up or down based on symptom control. They can screen for complications of diabetes, including kidney function tests, eye exam referrals, and foot assessments. This isn't ad hoc care. It's structured, evidence-based chronic disease management that follows clinical guidelines, the same guidelines physicians use.

Preventive care is the other side of that coin. Your NP can keep you up to date on cancer screenings, vaccinations, cardiovascular risk assessments, and mental health check-ins. They can order routine bloodwork to catch early warning signs before they become full-blown conditions. At Care&, on-premise lab work means you can often have your blood drawn during the same visit, rather than making a separate trip to a lab and waiting weeks for results. That kind of efficiency adds up over time, especially when you're managing a condition that requires regular testing.

What Does an NP-Led Clinic Look Like in Practice?

The concept of an NP-led clinic is still relatively new to many Torontonians, so it's worth describing what the experience actually feels like. When you walk into Care& Family Health, you're not entering a walk-in clinic with rotating providers and seven-minute visits. You're booking an appointment with your own Nurse Practitioner, someone who knows your name, your history, and what you discussed last time. Appointments are unrushed, which means there's time to ask questions, talk through options, and make decisions together.

Care& operates on a membership model. For $450 plus HST per year, members get unlimited in-person, phone, and video visits. There's also a pay-per-visit option at $100 per appointment for those who prefer flexibility. The clinic is not covered by OHIP, which is a fair question to address directly. The membership model is what allows Care& to offer longer appointments, consistent provider matching, and features like the Care& app where you can view your health records, message your NP, and request prescription refills. For a full breakdown, check the membership pricing page.

With two locations in Toronto, Yorkville and Lawrence Park, the clinic is accessible to a large part of the city. The Yorkville location at 162 Cumberland Street is a three-minute walk from Bay Station, making it easy to reach by transit.

When to See Your Nurse Practitioner

If you're wondering whether a concern is "worth" an appointment, the short answer is almost always yes. Your Nurse Practitioner is there for the full range of family practice needs. That includes acute issues like infections, rashes, injuries, and sudden pain. It includes ongoing concerns like fatigue, mood changes, or symptoms that have been lingering. And it includes the preventive stuff you might be putting off: screening tests, vaccinations, sexual health check-ups, and annual physicals.

If you currently have a family doctor through OHIP and you're happy with the care you're receiving, that's a perfectly good option. But if you're one of the many Torontonians who can't get an appointment for weeks, feel rushed during visits, or don't have a family doctor at all, an NP-led clinic like Care& is worth serious consideration. The appointments are longer. Your provider knows your history. And the care you receive is clinically equivalent for the vast majority of family practice concerns.

Many people find their way to Care& Family Health because they've been on a waitlist for a family doctor for over a year, or because they've been relying on walk-in clinics where every visit means starting over with a new provider. If that sounds familiar, a family practice built around continuity can make a real difference in how well your health is managed.
