Program Overview
The Occupational Hygiene (OH) emphasis is designed to fulfill the competencies required of the field to meet standards set by the International Occupational Hygiene Association and permit subsequent professional accreditation as a Registered Occupational Hygienist, via post-graduation examination.
The Environmental Public Health (EPH) emphasis is designed to meet the needs of those students who want competencies, as they exist in the OH emphasis, but apply them to ambient/outdoors environments, instead of work environments. This emphasis will accommodate graduates choosing to work in government (all 3 levels) or private firms assessing and interpreting the impact of contaminants (chemical, physical and biological) on the health of communities exposed via air, water, soil and food.
Occupational hygiene is a multidisciplinary profession drawing upon many basic and applied disciplines in the life, physical, engineering and behavioural sciences. The main aim of the profession is the prevention of disease and injury arising from the workplace. It involves the identification of health hazards, the evaluation or assessment of the extent of risk posed by the hazards, and the elimination or control of the risks. Health hazards typically found in the workplace include chemicals; physical agents, such as noise, heat, vibration and radiation; and biological agents, such as bacteria, fungi and viruses. These risks often extend beyond the workplace and into the ambient environment. In addition, ergonomic and safety hazards are encountered in workplaces, and their identification and control are part of an integrated approach to managing health, safety and environment.
Occupational Hygienists require a sound understanding of modern technology and industrial processes, and their impact on health and safety. Also they must understand the political, psycho-social and economic context in which they operate and they must work effectively with medical/clinical, engineering, and human resources professionals, employees/workers as well as business/organizational leaders and workplace stakeholders such as union and labour leaders. Occupational Hygiene is a well established profession, with professional competency standards, set by both the Canadian Registration Board of Occupational Hygienists (CRBOH) and the American Board of Industrial Hygiene (ABIH).
Program Objectives
The objective of this degree is to train Occupational Hygiene professionals to anticipate, identify, assess, and manage risks to health posed by hazardous materials, agents and processes. Although the focus is the occupational environment, graduates can also apply these principles in non-occupational settings within built environments. Key themes of the program are; evaluation of exposures to hazards, devising effective hazard controls, and developing management strategies to optimize occupational health.
Upon completion of the program, graduates will be able to:
- Identify physical, chemical, biological and psychosocial agents, factors, stressors generated or associated with defined sources, operations or processes
- Describe the effects of exposure to workplace hazards and scientific methods used in hazard analysis and risk assessment
- Develop and implement control strategies to mitigate or reduce exposure and evaluate the effectiveness of these interventions
- Demonstrate knowledge of the principles of physical and biological sciences necessary for developing competence in the theoretical and practical aspects of occupational hygiene
- Demonstrate knowledge of ergonomics, occupational safety, accident prevention, and, occupational health and safety considerations of labour relations
- Demonstrate the critical skills required in the review of scientific literature, and a knowledge of research methods, including epidemiological and statistical techniques as they apply to occupational health
- Communicate effectively with labour, management, the public and other members of the scientific community
Explain the influence of workplace hazards on the general environment and the role of the hygienist in environmental protection
Students are provided with hands-on experience during field exercises in actual industrial and occupational environments. This is a vital component of their professional training.
Career Opportunities
Graduates in OEH are in demand across Canada, entering directly into responsible positions. Approximately 35% of the graduates are working in the industrial sector: employed in manufacturing, petrochemical, aerospace, pharmaceutical, steel, mining and other industries. Over one quarter of the graduates work in the service/public sector, for employers such as municipal, provincial and federal governments, school boards, colleges, universities, hospitals and public utilities, in corporate health and safety functions. Fifteen percent of the graduates are employed by provincial and federal governments in a regulatory/policy role. Another 15% of the graduates are employed as consultants, either independently, in small groups or for larger consulting firms. In addition, some of the graduates have gone on to careers in research and academia.
Admission Criteria
MPH students are admitted under the General Regulations of the School of Graduate Studies (SGS) and should hold an appropriate bachelor’s degree or its equivalent from a recognized university with at least a mid-B average in final year of the degree, or in the last 5.0 full course equivalents completed at a senior level. Proof of English Language Proficiency is required (See below).
Minimum Admission Requirements for MPH Occupational and Environmental Health
- Ideally, applicants have completed courses in a variety of areas including chemistry, physiology/toxicology, statistics, mathematics, biology, and physics.
- Successful applicants have obtained their undergraduate degree in the physical, life, engineering or environmental sciences.
- It is highly recommended that applicants have taken at least one undergraduate statistics course. To fulfill this admission requirement, applicants should have successfully completed this course during their undergraduate education, prior to the application deadline.
- Previous applicable experience is taken into account, but is not necessary for admission.
- All suitable applicants are invited to an interview (in person or by telephone/internet).
Each year we accept approximately 15 students in total, with varied academic science backgrounds. Applicants must choose either the Occupational Hygiene or Environmental Public Health emphasis.
International applicants
No applicant will be admitted without evidence of English Language Proficiency (ELP). As per the policy of the School of Graduate Studies (SGS), the following applicants do not have to provide direct supporting evidence of ELP in the application.
- A Canadian citizen who studied at a Canadian university where instruction is in English or French;
- Any applicant who has obtained a qualifying undergraduate degree from an institution that is recognized by the University of Toronto, and where the language of instruction and examination is uniformly English.
If either criterion above is satisfied, the application can be submitted without test scores or other proof of ELP.
Otherwise, an approved test of English Language Proficiency must be submitted at the time of application. Scores must meet the minimum requirements set by SGS and must be valid (taken within 2 years of submission of the application). See SGS website for details.
If an applicant is required to submit proof of ELP and does not include this with the application, by the application deadline, the application will be considered incomplete and inadmissible.
Applicants who studied outside Canada must consult the School of Graduate Studies website to determine whether evidence of ELP can be waived. The SGS website lists those countries where university instruction in English will be recognized without further documentation. Click here for more information.
The SGS website also has an international degree equivalency tool that may be consulted to determine minimum admission requirements for graduates from recognized institutions outside Canada. Admission eligibility cannot be determined until a complete application is submitted. We are not able to review or assess your academic record without an official application to a graduate degree program, including payment of the appropriate application fee.

Practicum Placements
The required practicum (CHL6010Y) provides an opportunity for learners to apply the theory and knowledge gained in coursework by engaging in new projects and experiences in professional settings. The placement should entail the types of activities normally carried out by the preceptor and cover as many aspects of occupational hygiene as possible. A practicum cannot be undertaken until the pre-requisite courses have been completed. The student will be placed, for a minimum of 16 weeks under the direct supervision of an Occupational Hygienist or Environmental Public Health Scientist, approved by the faculty. Since the student is expected to be of some direct benefit to the preceptor and the supporting agency, the student is normally paid a stipend during the placement.
The Program Director will assist in the identification and selection of appropriate practicum placement. Some practicum placements may be assigned through a competitive process. Each practicum supervisor must be approved by the Program Director prior to the beginning of the placement.
