The Climate Atlas allows you to explore how climate change can impact your health. Hot temperatures can make pollution problems worse, lead to more dangerous heat waves, greatly increase the risk of forest fires, and more. Understanding the magnitude of these changes and risks allows citizens, politicians, and planners to take meaningful action to mitigate and adapt. The following maps describe some of the key climate impacts facing the health of Canadians:

Many Canadians welcome the arrival of hot summer days as respite from our long, cold winters. Understandably, we tend to think of more summer heat as a good thing. But too much heat can be dangerous.

We often think about climate change as something abstract or remote. We hear scientists talking about melting ice caps, see images of drought in faraway places, or browse through news coverage of exotic weather disasters. But climate change is having effects right here and right now in Canada. And the risks aren’t just theoretical or abstract. The effects of climate change promise to be up close and personal, affecting the everyday lives and health of Canadians. As Jeff Eyamie of Health Canada says, “The most immediate and personal impact of climate change is the health impact.”

Canada has some of the cleanest air on the planet.[1] But the truth is, many Canadians—especially in urban centres—are finding it more difficult to breathe easy. For example, instead of fresh spring air, the first day of Toronto’s 2019 spring break arrived with an air quality warning thanks to high levels of air pollution. In 2023, waves of air pollution passed through Canada during the summer surge of wildfires - impacting the health of many residents in large Canadian cities.[2][14]

Dr. Amber Fletcher grew up on a farm and has a strong appreciation for farmer knowledge and the importance of rural environments and communities. Now, as an academic at University of Regina, she studies how farmers are seeing and feeling the impacts of climate change in their fields and daily lives. She’s interested in the critical contributions that women make to farm life, especially during climate extremes such as floods and droughts.   Recommended Video Citation Climate Atlas of Canada.

Near the end of the century, the City of Toronto could experience nearly two months of +30 °C days a year, according to climate projections. To address the growing risk of future heat waves, local faith leaders have created a network of cooling centres in churches, mosques, temples and synagogues, and are mobilizing their congregations to provide support for susceptible populations. For City Councillor Gord Perks, this example of grassroots community resilience makes him hopeful about the future.   Recommended Video Citation Climate Atlas of Canada. (2018).

The climate determines almost everything about how we design, build, and live in our cities. The streets and sidewalks, businesses and homes, parking lots and public transit that we use every day have been created to suit our climate. Now, with our climate changing, we need to re-think important aspects of how we live our urban lives.

Today, over 80% of Canada’s population lives in cities. We know that cities will soon face increased climate change impacts, such as more frequent and intense extreme weather events.  The research series Building a Climate-Resilient City by the Prairie Climate Centre outlines policy steps that cities can take to engage in climate risk management in a range of areas, including transportation, agriculture, electricity infrastructure, disaster preparedness and emergency management.
