Careers in Respiratory Therapy: What Respiratory Therapists Do and How to Become One in Canada

October 20, 2026

Every breath we take relies on a complex, vital system. When acute trauma, severe illness, chronic disease, or premature birth compromises a person's ability to breathe, specialized healthcare professionals step in immediately. Registered Respiratory Therapists (RRTs) are critical clinical specialists trained in airway management, cardiopulmonary medicine, and life-support technology.

In Canada, National Respiratory Therapy Week takes place annually during the last week of October (October 25–31). Promoted by the Canadian Society of Respiratory Therapists (CSRT), this week highlights the vital role RRTs play across emergency rooms, intensive care units, operating rooms, and community care settings.  

While nursing and personal support work are often the primary focus of healthcare discussions, respiratory therapy represents one of the most dynamic, high-tech, and in-demand medical fields in Canada today. This comprehensive guide outlines what respiratory therapists do daily, essential skills for success, and step-by-step pathways to becoming an RRT in Canada.

Why October Celebrates Respiratory Therapy

Respiratory Therapy Week provides an ideal occasion to spotlight this specialized discipline. From managing mechanical ventilators during critical health crises to supporting patients living with chronic respiratory conditions like asthma or Chronic Obstructive Pulmonary Disease (COPD), RRTs are essential members of multidisciplinary clinical teams.

What Does a Respiratory Therapist Do?

Registered Respiratory Therapists diagnose, treat, manage, and care for patients with cardiopulmonary disorders. Their responsibilities span from newborn resuscitation in neonatal intensive care units (NICUs) to complex life support in adult ICUs.

Core responsibilities of an RRT include:

Airway Management and Life Support

RRTs are airway specialists. They assist physicians during endotracheal intubation, manage invasive and non-invasive mechanical ventilators, maintain tracheostomies, and manage ventilator weaning protocols in critical care units.

Diagnostic Testing and Blood Gas Analysis

Therapists perform diagnostic procedures such as arterial blood gas (ABG) sampling, pulmonary function testing (PFT), and sleep apnea diagnostic studies to evaluate lung function and oxygenation levels.

Administering Inhaled Medications and Aerosol Therapies

RRTs calculate, administer, and evaluate inhaled therapeutic medications, medical gases (such as oxygen and nitric oxide), and chest physiotherapy to clear secretions and improve ventilation.

Emergency Response and Trauma Resuscitation

In hospital settings, RRTs are core members of cardiac arrest teams (Code Blue), trauma resuscitation teams, and high-risk neonatal delivery teams.

Essential Skills for Respiratory Therapists

Thriving in respiratory therapy requires a balance of scientific aptitude, technical competence, and interpersonal strength.

  1. Critical Thinking Under Pressure: RRTs must analyze rapidly changing clinical data—such as blood gas results or ventilator alarms—and make immediate decisions during life-threatening crises.
  2. Technical and Technological Aptitude: Managing sophisticated life-support systems, ventilators, and diagnostic equipment requires comfort with complex technology.
  3. Compassion and Communication: Patients experiencing severe breathlessness often feel extreme anxiety. Effective RRTs communicate calmly and reassure patients during frightening medical moments.
  4. Interprofessional Collaboration: Therapists work alongside physicians, nurses, anesthesiologists, and physical therapists to coordinate holistic patient care plans.

Step 3: Understand Course Work and Prerequisites

Before enrolling, researching program structures helps ensure academic success. Reviewing respiratory therapist classes outlines typical course progression, laboratory simulation expectations, and clinical practicum requirements.

Step 4: Pass the National Credentialing Exam

Upon graduation, candidates must pass the Canadian Board for Respiratory Care (CBRC) national entry-to-practice examination. Passing this exam grants eligibility for registration across Canadian jurisdictions.

Step 5: Register with a Provincial Regulatory Body

To practice legally as an RRT, graduates must register with their respective provincial regulatory body (such as the College of Respiratory Therapists of Ontario, CRTO) and maintain active professional liability insurance.

Frequently Asked Questions (FAQs)

What is the difference between a Registered Nurse (RN) and a Respiratory Therapist (RRT)?

An RN manages broad, holistic patient care across multiple organ systems and health needs. An RRT is a specialized clinical expert focused specifically on cardiopulmonary assessment, mechanical ventilation, and advanced airway management.

How long does it take to become a respiratory therapist in Canada?

It typically takes 3 to 4 years of full-time post-secondary study in an accredited diploma or degree program, followed by passing the CBRC national credentialing exam and registering with a provincial college.

Can Canadian Respiratory Therapists work in the United States?

Yes. Canadian-trained RRTs are eligible to work in the US under TN visa status, provided they satisfy state licensing requirements and pass the National Board for Respiratory Care (NBRC) exams.

Is respiratory therapy a good career in terms of job stability?

Yes, respiratory therapy is considered one of Canada's most stable healthcare fields. Growing aging populations, rising chronic lung conditions, and expanding critical care units drive steady demand for qualified RRTs.

What certifications do respiratory therapists need?

In addition to their RRT license, therapists working in hospital acute settings usually hold certifications in Basic Life Support (BLS), Advanced Cardiovascular Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Neonatal Resuscitation Program (NRP).
