CANADA’S CLIMATE EMERGENCY
Climate change is no longer a distant or isolated issue. It is a whole-of-society emergency affecting the systems Canadians depend on every day.
Rising temperatures, extreme weather, ecological degradation, and economic disruption are converging into a single, interconnected crisis.
Understanding this emergency requires looking across sectors—not in isolation.
Explore the impacts below.
CLIMATE & SCIENCE
The Reality
Canada is warming at approximately twice the global average, and even faster in northern regions.
Global temperatures have already crossed critical thresholds, increasing the likelihood of irreversible environmental changes.
Why It Matters
Climate change is not linear. As warming increases, risks accelerate—triggering feedback loops such as permafrost thaw and ecosystem collapse.
These changes are already underway and are reshaping Canada’s environment, economy, and infrastructure.
What This Means
- Increased frequency and severity of extreme weather
- Loss of ecological stability
- Greater uncertainty in planning and policy
EXTREME WEATHER
The Reality
Canada is experiencing more frequent and severe climate events, including:
- Heat domes
- Wildfires
- Flooding
- Severe storms
These events are becoming more destructive and less predictable.
Why It Matters
Extreme weather is no longer rare—it is becoming a defining feature of Canada’s climate.
Entire communities have been evacuated. Infrastructure has been destroyed. Recovery costs are rising rapidly.
What This Means
- Increased risk to lives and homes
- Growing pressure on emergency services
- Long-term disruption to communities and economies
HEALTH IMPACTS
The Reality
Climate change is already affecting the health of Canadians.
Heat events, wildfire smoke, and environmental changes are contributing to:
- Respiratory illness
- Cardiovascular stress
- Increased emergency room visits
- Premature deaths
Why It Matters
Health systems are not designed for repeated, large-scale climate-related shocks.
In addition to physical health impacts, climate disruption is also driving mental health challenges through displacement, loss, and uncertainty.
What This Means
- Increased strain on healthcare systems
- Greater vulnerability among at-risk populations
- Long-term public health challenges
FOOD & AGRICULTURE
The Reality
Climate extremes are disrupting food production in Canada and globally.
Droughts, floods, and heat waves are reducing crop yields and affecting livestock.
Why It Matters
Food systems depend on stable environmental conditions. As those conditions change, food security becomes less certain.
Global disruptions also affect food prices and availability in Canada.
What This Means
- Rising food costs
- Increased supply volatility
- Greater risk for vulnerable populations and communities
ECONOMY & FINANCE
The Reality
Extreme weather events are causing billions of dollars in losses each year.
Insurance systems are under pressure, and some assets are becoming increasingly difficult to insure.
Why It Matters
Climate risk is financial risk.
As impacts intensify, they affect housing markets, infrastructure investment, and economic stability.
What This Means
- Rising costs for governments, businesses, and households
- Increased financial system vulnerability
- Need for large-scale investment in adaptation and resilience
NATIONAL SECURITY
The Reality
Climate change is reshaping global and national security dynamics.
In Canada, the Arctic is warming rapidly, creating both environmental risks and geopolitical challenges.
Why It Matters
Climate-related disasters are already requiring military support for domestic response.
At the same time, global instability linked to climate impacts can affect migration, resources, and international relations.
What This Means
- Increased demand on defense and emergency systems
- New geopolitical pressures in the Arctic
- Greater need for coordinated national planning
NATURE & BIODIVERSITY
The Reality
Canada’s ecosystems are under increasing stress from climate change and human activity.
Wildlife populations are declining, and critical ecosystems such as the boreal forest are at risk.
Why It Matters
Healthy ecosystems provide essential services:
- Carbon storage
- Flood protection
- Clean air and water
Their degradation increases climate risks and reduces resilience.
What This Means
- Loss of natural protection against climate impacts
- Increased environmental instability
- Long-term ecological and economic consequences
