As we move through 2025, Canada continues to face several critical health challenges that impact individuals, families, and communities. While some issues have persisted over the years, others have grown due to lifestyle shifts, climate changes, and social factors.
Understanding these major health issues is key to prevention, early intervention, and building a healthier future for all Canadians.
What Is the Biggest Health Issue in Canada?
According to current public health data, mental health has emerged as the biggest health issue in Canada in 2025. The combination of rising stress levels, digital burnout, economic pressure, and post-pandemic aftershocks has caused a significant increase in anxiety, depression, and other mental health conditions.
Quick facts:
- 1 in 4 Canadians will experience a mental health issue in their lifetime.
- Youth mental health concerns are growing at an alarming rate.
- Access to affordable mental health care remains limited in many areas.
Solution:
More public investment in community mental health services, telehealth accessibility, and reducing the stigma around getting help are essential steps.
1. Mental Health Crisis: Anxiety, Depression, and Burnout
Mental illness now ranks among the top reasons Canadians take time off work or school. Children, teens, and young adults are particularly vulnerable in the digital age.
Common triggers:

2. Chronic Diseases: Heart Disease, Diabetes & Cancer
Chronic illnesses account for nearly 80% of deaths in Canada. The most common conditions include:
- Cardiovascular disease
- Type 2 diabetes
- Breast, prostate, and colorectal cancers
These conditions are often linked to lifestyle factors such as poor diet, lack of exercise, smoking, and alcohol consumption.

- Get regular screenings and physical activity.
- Quit smoking and limit alcohol intake.
3. Obesity and Unhealthy Lifestyles

Health risks of obesity:
- Type 2 diabetes
- High blood pressure
- Joint problems

5. Aging Population and Senior Care Gaps
Canada’s population is aging rapidly, with more than 20% of Canadians over the age of 65. This presents challenges in healthcare infrastructure, long-term care, and caregiver burnout.
Concerns include:

First Nations, Inuit, and Métis populations continue to experience systemic health disparities due to colonization, racism, and limited access to healthcare.

What You Can Do:
- Support Indigenous-led health initiatives.
- Learn and acknowledge the truth of health injustices.

7. Environmental and Climate-Related Health Issues
Climate change is now considered a health emergency. Rising temperatures, air pollution, and extreme weather events are directly affecting the health of Canadians.
Impacts include:
- Respiratory issues from wildfire smoke
- Heat-related illnesses
- Vector-borne diseases (e.g., Lyme disease, West Nile virus)
What You Can Do:
