As summers become longer and hotter under climate change, many Canadians will be seeking relief at lake beaches. But hotter summers and changing precipitation make favourable conditions for algal blooms to grow in the water, which can produce toxins that are harmful to human health. Experts, Indigenous communities, and residents in the Lake Winnipeg area are all too familiar with the impacts of algal blooms on health, as they discuss in this video

“What’s the Buzz” tells the story of Canada’s increase in mosquito-borne diseases over the last 20 years, largely due to climate change. With warmer, wetter weather in our future, experts expect these diseases will become more common. Canadians are being impacted while also responding to an increase in West Nile Virus and adapting to lessen their risk.

When you think about dangerous animals, big or poisonous creatures probably come to mind. But in fact, mosquitoes are one of the most deadly animals in the world.[1] That’s because mosquitoes can transmit a range of diseases which are of major public health concern globally.

Wildfires are becoming increasingly frequent and intense in Canadian summers.[1] In 2018, British Columbia saw its worst fire season in history, burning 1.3 million hectares of land.[2] This was just two years after record-breaking fires devastated the city of Fort McMurray in Alberta, costing $9 billion in losses.[3] With this increase in wildfires caused by climate change[4], we’re seeing more and more health impacts to Canadians.

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.
