2023 was a record year for Canadian wildfires. At times, it felt like the whole country was burning. 2024 was better, but still devastating and many Canadians face a new reality: the seemingly never-ending possibility of a summer choked with smoke and flames. 

Wildfires consumed record-breaking chunks of the country in 2023, thanks to a dry, hot spring.

Disease and pests are killing or weakening trees and forests are continuously managed for industry, homes and infrastructure, a practice that has made forests more flammable.

Here’s a breakdown of how fires start and why they seem to be getting worse.
