Under the Public Health Act, environmental public health professionals are designated to enforce specific regulations and standards that include—but are not limited to—regulations related to food, swimming pools, housing, and personal services.
Environmental public health professionals support food facilities, including restaurants, food processing facilities, and food service establishments, to ensure food premises maintain a high standard of food safety and sanitation to help prevent food-borne illness. EPHPs support food safety in the following ways:
-
Issuing permits or licenses and granting health approvals to facilities that offer food to the public, like restaurants, food trucks, grocery stores, daycares, and nursing homes
-
Inspecting food facilities to assess the operational environment and food safety practices
-
Following up on complaints and inspecting food facilities to assess food safety
-
Offering food safety information and education to operators and members of the public
-
Providing guidance on safe food handling practices for special events, markets, bake sales, and other functions
A safe water supply is fundamental to the health and well-being of all communities. Environmental public health professionals work with local water suppliers and operators to ensure drinking water is safe to drink. EPHPs inspect and monitor drinking water supplies for compliance with regulatory requirements, conduct water sampling, and provide the public with information on how to protect and improve their water quality. Additionally, they may issue health orders or advisories when there are health risks associated with the drinking water supply.
Environmental public health professionals monitor and ensure the safety of recreational water, including public pools, commercial pools (for e.g., hotels, stratas), hot hubs, and spray parks. They work closely with facilities to ensure that public health and safety are protected, and they educate operators and facilitate improvements.
Environmental public health professionals collaborate with partner agencies to ensure adults and children living in or using care facilities such as residential care facilities and daycares have access to safe food, shelter, and a safe and healthy environment. They conduct regular inspections of care facilities to ensure essential health, safety, and care standards are met and work closely with care providers and families to ensure quality care for individuals in licensed care facilities.
For special events and festivals, environmental public health professionals work with event organizers and vendors to ensure the health and safety of attendees. They look at areas regulated under the Public Health Act that include but are not limited to food, personal services, potable water systems, and wastewater systems—all of which could result in the spread of communicable diseases if not properly inspected and monitored.
Environmental public health professionals work with health care professionals and the public to limit the spread of communicable diseases and promote infection and disease control. Their work includes:
-
Providing education to operators on the prevention of communicable diseases
-
Following up on communicable disease cases to mitigate the spread of disease
-
Providing education to operators on infection control measures to implement in their facilities to limit spread
-
Providing data to inform and advise decision-making during outbreaks
Given their diverse skill set, environmental public health professionals are often deployed in various emergency response situations. In these situations, EPHPs might be called upon for any of the following duties:
-
Ensuring emergency reception centres and impacted facilities are operating in a safe manner
-
Assessing that there is safe drinking water
-
Assessing environmental hazards
-
Conducting case and contact management
-
Educating and advising the public on the current public health recommendations (for e.g., physical distancing, masking)
-
Enforcement of public health legislation
Environmental public health professionals work with tobacco and vapour product retailers to ensure that their operations are in compliance with the various regulations and acts that apply to them. EPHPs use a combination of education, monitoring, and enforcement to achieve this.
Ambient and indoor air quality affects the health of all communities. Air quality is impacted by different pollutants, including residential wood smoke, exhaust, moulds, radon, road dust, wildfire smoke, and industry emissions. Environmental public health professionals may conduct investigations and provide recommendations and advice to the public to mitigate health risks associated with poor air quality. This may include testing and monitoring indoor air quality to ensure it meets the requirements set by various regulations and acts so that we can all breathe clean air.
Environmental public health professionals integrate health promotion into all aspects of their work. They work closely with other health promotion professionals and the public to promote best practices for environmental health.
Environmental public health professionals collaborate with Medical Health Officers to ensure safe and healthy environments where people live, work, and play. EPHPs advise on and support the management of various health hazards that occur in our communities, including boil water advisories and flood warnings.
What do environmental public health professionals do?
Encompassing all aspects of our lives, from air to water to food, to employment and recreation, to our homes and families, environmental public health is a cornerstone of safe, functional, and thriving communities.
Working with provincial and regional health authorities, health counties, tribal councils, and provincial and federal governments and ministries, these environmental public health professionals (also known as public health inspectors and environmental health officers) are essential to keeping our water, food, land, air, and facilities safe.

However, not every Canadian is safe at all times, due to a lack of social equity, unforeseen events, and ongoing changes in our society and our environment. But no matter the cause, environmental public health professionals are continually learning and adapting to anticipate and address challenges to every person’s health and safety, with the goal of making Canada better for everyone.
How do I become an environmental public health professional?
Environmental public health professionals have specific professional skills obtained through specialized education, training, and national certification in Canada.
While career paths and levels of expertise vary, typically an environmental public health professional must:
1
Hold an approved academic qualification, such as a bachelor’s degree in Environmental Health.
2
Complete a minimum of 12 weeks of practicum experience.
3
Pass an exam comprising written and oral components in order to receive a Certificate in Public Health Inspection (Canada), CPHI(C), from the Canadian Institute of Public Health Inspectors.
Environmental public health professionals must also maintain their technical skills and knowledge by participating in ongoing professional development activities, and while building a range of other qualities that play an important part in their work. These include effective communication and problem-solving skills, empathy, curiosity, and a desire to make a difference.
Amanda Hepp Helps Keep Recreational Waters Safe
Amanda Hepp, CPHI(C)
Public Health Inspector
A dedicated, part-time public health inspector at Alberta Health Services in Lethbridge, Alberta, Amanda previously worked as a full-time health inspector for a vast rural area in Northern Alberta.

Dana Trefry Prevents Outbreaks of Disease
Dana Trefry, CPHI(C), BSc., BHSc.
Health Protection Consultant, Nova Scotia Health Authority
When Dana Trefry started university in 2003, she had no idea that the environmental public health profession even existed. That changed when she took her first microbiology course at Cape Breton University, during which she “fell in love with microbes” and learned about outbreaks and what can be done to prevent them. This piqued Dana’s interest in environmental public health and pointed her in the direction of CPHI(C) certification.Over the span of 13 years of working with the Nova Scotia provincial government, she built a career teaching others how to prevent illness, especially through food safety/infection control inspections.
During a typical day on the job, Dana helps lead the Health Protection team deliver their immunization programs and communicable disease case management program. She collaborates with public health inspectors and public health nurses daily on their work, provide guidance on outbreaks, implements and evaluates new projects and manages the Mobile Outreach Immunization team.The Outreach team delivers immunization to the clinics in community, focusing on rural locations and meeting populations for whom barriers exist where they are at. Although these clinics have primarily administered Covid-19 vaccines, Dana and her team are exploring different uses for mobile outreach, with the goal of continuing to strengthen public health for all.
Samarjeet Singh Embarks on a Career in Environmental Public Health
Samarjeet Singh, BHSc.
Public Health Inspector Intern, Manitoba Health
Before pursuing a career in environmental public health, Samarjeet Singh was serving as a second officer in the merchant navy. However, he found himself drifting to a different shore and graduated with a Public Health degree from Cape Breton University in 2023. Based on an exceptional university experience, the mentorship of amazing professors, and an informative summer student position at the Grey Bruce Health Unit (GBHU), Samarjeet has gained a great understanding of the environmental public health profession—particularly the importance of prevention activities. Now, he’s well on his way to achieving his goals of becoming a public servant and keeping people safe and healthy.
As a public health inspector intern in Manitoba, Samarjeet finds no two days the same, with each presenting new challenges and motivations. He fondly recalls a particular experience with the GBHU, when he helped an elderly man interpret a well water sample so that he could understand the risks associated with the water quality. When Samarjeet received a voice message the next day that said, “Thank God for people like you,” he knew he was making a real difference.
