Yes, Canada has physician assistants (PAs), though the profession is much smaller and less established than in the United States. Roughly 500 PAs practice across the country, working primarily in primary care, emergency medicine, and increasingly in surgical specialties. The role has roots in the Canadian military dating back to the 1960s, and civilian PA practice has been growing steadily since the early 2000s.
Military Origins of the PA Role
The Canadian Forces have trained and employed military physician extenders since the 1960s, initially calling them Medical Assistants before renaming the role Physician Assistant in 1984. The military needed skilled medical providers in locations where it wasn’t practical to send physicians: remote northern outposts, naval ships, and small or dispersed deployments in Canada and abroad. PAs filled that gap by providing primary care, emergency care, and even emergency dental services under physician oversight.
When all Canadian military hospitals closed in the mid-1990s following Cold War budget cuts, training military PAs became a challenge. Civilian hospitals were unfamiliar with the role and needed education about what PAs could do and how they should be trained. At the same time, the military faced pressure to have accredited and certified health professionals in its ranks. Since no civilian equivalent existed in Canada at the time, this prompted the creation of a civilian-accredited military training program and the founding of the Canadian Association of Physician Assistants (CAPA). That military push became the foundation for civilian PA practice across the country.
Which Provinces License PAs
PA regulation in Canada is handled at the provincial level, and coverage is uneven. As of the most recent policy updates, PAs are licensed to practice in four provinces: Ontario, Manitoba, Alberta, and New Brunswick. Manitoba was the first to formalize legislation, passing a clinical assistant registration amendment in 1999 through the College of Physicians and Surgeons. By 2010, the province had 14 PAs, 45 clinical assistants, and 22 PA students, along with updated legislation that specifically named PAs as licensed health professionals.
Alberta followed in 2009, when the provincial Minister of Health requested that the College of Physicians and Surgeons of Alberta develop a regulation process for PAs. British Columbia has more recently opened a pathway, with the College of Physicians and Surgeons of BC now listing registration information for certified physician assistants. Several other provinces have conducted reviews or analyses of whether to incorporate PAs into their medical workforce, but formal regulation hasn’t been implemented in every jurisdiction.
Education and Certification
Canadian PA programs are typically two years in duration. Graduates must pass the PA Entry to Practice Certification Examination, administered by the Physician Assistant Certification Council of Canada (PACCC). This national exam is written upon successful completion of a recognized Canadian PA program and results in the designation of Canadian Certified Physician Assistant.
What Canadian PAs Can Do
The scope of what a PA does in Canada depends heavily on the supervising physician. Unlike nurse practitioners, who in some provinces can practice with a degree of independence, PAs always work under physician delegation. The supervising physician decides which procedures the PA can perform and what responsibilities they’ll take on. This makes the PA-physician relationship central to how the role functions day to day.
In practice, a new PA typically goes through a structured evaluation period. Over about two months, they record the medical issues they’ve managed, prescriptions they’ve initiated, and investigations they’ve ordered. A formal review then determines which clinical problems the PA handled successfully, whether they used lab and diagnostic tests correctly, and whether they prescribed medications appropriately. The tasks they demonstrate competence in become their established scope of practice. From that point, the PA can independently see patients whose concerns fall within their confirmed skill set, operating under a medical directive from the supervising physician.
PAs in Canada do not have independent prescribing authority. They can prescribe medications, but only under the supervision and delegation of a registered physician. How much prescribing latitude a PA gets depends on the trust and working relationship between the PA and their supervising doctor.
Where PAs Work in Canada
Most of Canada’s approximately 500 PAs work in primary care and emergency medicine. Surgical specialties are a newer and growing area. Research from the Canadian Journal of Surgery notes that PAs have only recently started working in acute care surgery settings, a contrast to the United States where surgical PA roles are well established. Supervising physicians who employ PAs report high satisfaction with the arrangement, though researchers have noted that stable organizational funding remains a challenge for expanding PA positions.
How PAs Differ From Nurse Practitioners
The two roles overlap in some clinical functions but differ in training, regulation, and autonomy. Nurse practitioners in Canada come from a nursing background and, depending on the province, can practice with significant independence. In some jurisdictions, nurse practitioners no longer need a formal partnership agreement with a physician and can theoretically set up independent practices. PAs, by contrast, always work under a physician’s supervision. Their training is modeled on a medical education framework rather than a nursing one, and their scope of practice is defined by their supervising physician rather than set by a regulatory body in advance.
This distinction matters for how PAs are integrated into clinics and hospitals. A PA adds capacity to an existing physician’s practice, essentially extending what that doctor can accomplish. A nurse practitioner can function more as a standalone provider, though both roles are increasingly seen as essential to addressing Canada’s primary care access challenges. The roughly 500 practicing PAs represent a much smaller workforce than Canada’s nurse practitioners, and expanding that number depends on more provinces creating clear regulatory frameworks and funding models.
