When the three hottest months of the high-sun season roll around, many Canadians are used to dealing with pests - be it those pesky mosquitoes when working out in the yard or sticky ticks when walking in the forest. But in a warming world, these pests are becoming more than just a nuisance for Canadians.

Lyme disease is on the rise in Canada, due in part to climate change. Warming temperatures are allowing blacklegged ticks - the species that can carry Lyme disease in central and eastern Canada - to move into new territories. Hear from the scientists, medical professionals, and citizens on the front lines of this infectious disease issue, and how we can prepare and protect our families and communities from this risk.

When wildfires are at your community’s door, there’s only one thing to do: evacuate. As communities are uprooted and fires are being fought, people are put under extreme stress that leads to both short- and long-term mental health impacts.

In August 2018, British Columbia declared a provincial state of emergency due to forest fires. At its peak, there were over 560 wildfires burning in the province. The smoke from the fires travelled thousands of kilometres, causing air quality warnings to be issued across BC, Alberta, and as far away as southern Manitoba.[1]

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.

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]

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.”

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.

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.
