Canadian Environment Week 2026
Established in 1971, Canadian Environment Week celebrates Canada’s environmental accomplishments and encourages Canadians to contribute to conserving and protecting their environment.
From May 31 to June 6, 2026, join us on social media using #EnviroWeek. Celebrate and safeguard our environment and take action to protect the places we love.
Some special days include:
- June 3: Canada's Clean Air Day
- June 5: United Nations World Environment Day
Solutions for a healthier environment
Canadian Environment Week highlights the collective efforts we are taking, both at home and around the world, to build a healthier, more sustainable future. Environmental challenges such as climate change, biodiversity loss, and plastic pollution do not stop at borders.
Canada has the second largest land mass and the longest coastline in the world. Our actions at home have impacts on a global scale. Our commitment to protect 30% of lands and waters by 2030 matters well beyond our borders. When Canada protects nature, we help protect a meaningful share of the planet’s remaining intact ecosystems. Learn more about our plan to do just that by reading A Force of Nature: Canada's Strategy to Protect Nature.
Caring for our shared planet is a global responsibility. Protecting it requires cooperation, both internationally and at home. Canada is working with global partners to advance solutions, such as:
- tackling plastic waste
- supporting a circular economy
- strengthening climate action
- protecting nature
These efforts complement actions at home and help drive meaningful progress worldwide.
Clean Air Day in Canada
In Canada, Clean Air Day is celebrated on the first Wednesday of June. On June 3, we will take the time to recognize the importance of clean air for our health, the environment and the economy. Climate change is resulting in longer and drier summers, which contributes to increased wildfire risk. During wildfire events, Environment and Climate Change Canada may issue air quality advisories and warnings when wildfire smoke threatens our communities. Learn more about air quality in your community and what you can do to help protect the air we breathe.
World Environment Day
Every year, World Environment Day is celebrated on June 5, led by the United Nations Environment Programme. This year, the focus is a global call for climate action. This theme recognizes that addressing climate change is no longer just a moral obligation; investing in a clean future is an economic imperative. Canada is committed to fighting climate change and to leading in a global economy that needs decarbonized goods, services, technologies, and expertise. Through initiatives like Canada’s Rapid Extreme Weather Event Attribution System, we are strengthening the scientific evidence that links extreme weather events to climate change. This helps Canadians better understand climate risks and inform action.
It is a global effort to take care of our shared planet.
