About risk assessments
The Public Health Agency of Canada (PHAC) assesses risks to public health to:
- identify emerging threats
- describe, anticipate or estimate public health risks
- develop recommended actions
- explore future outcomes of risk
A risk assessment is undertaken on a public health threat to understand and estimate risks and potential responses. An assessment does not necessarily indicate an elevated level of risk to the public or that a risk is expected.
A risk assessment informs PHAC and other professionals responsible for managing public health risks. The assessment supports planning, responses and decision making to improve health outcomes for people living in Canada or Canadians abroad.
Risk assessments
Active
The following events are being actively monitored by PHAC for emerging information that could affect the risk.

Description of types of risk assessments
Risk profile
A risk profile is a detailed characterization of a possible public health risk that may impact people living in Canada or Canadians abroad. Such a risk may require further action. A risk profile explores multiple potential concerns associated with the situation and provides information and expert advice.
A risk profile helps to:
- understand the risks associated with the situation
- inform actions to guide a response by PHAC and other public health authorities
Rapid risk assessment
Rapid risk assessments are reports that use standardized scientific methods for understanding:
- likelihood of a public health threat occurring
- impact if it were to occur
The methods allow it to be conducted relatively quickly, taking into account all relevant intelligence, including:
- new and emerging information
- scientific evidence
- readily available data
- expert knowledge and opinion
The process involves gathering, analyzing and assessing this intelligence to provide risk estimates for a specific period and location or population.
The risk estimates include a measure of uncertainty because they rely on information available at a specific point in time. This information can be incomplete or difficult to validate. Risk assessments may be updated as new evidence becomes available.
Pandemic risk scenario analysis
A pandemic risk scenario analysis documents plausible pandemic scenarios, or scenarios leading up to a pandemic, that could occur in the future. Multiple government organizations work together to examine which scenario is the most likely, as well as the worst-case scenario. Situations that have pandemic potential both nationally and globally are considered when working through the scenarios.
This informs early warning, prevention and preparedness activities. Critical monitoring points are established to provide early warning of change should any conditions suggest an increase in risk.
Methodology
In 2022, the Public Health Agency of Canada established a coordinated approach to public health risk assessment. Given the broad range and complexity of public health hazards, establishing risk assessment methods provided a systematic approach to:
- gathering, assessing and documenting information about a public health hazard
- assigning a level of risk to inform decision making
Current methods
One Health approach to risk assessment
One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems. One Health threats can include many hazards, such as:
- biological
- chemical
- environmental
- meteorological
The Public Health Agency of Canada, in collaboration with a multi-sectoral team, has developed a One Health Approach to Risk Assessment Framework. The framework is a series of modules aimed at risk assessors and those who request risk assessments within multiple sectors and disciplines in Canada. The goal is to achieve high-quality risk assessments that will increase understanding of risks to enable prompt and effective action for the health of people, animals, plants and ecosystems in Canada.
