Canada is experiencing a concerning trend of longer, larger, and more destructive wildfire seasons, as revealed by a recent analysis of fire records spanning six decades conducted by the Canadian Forest Service. The study indicates that the escalation in wildfires is not due to a higher frequency of fires but rather a smaller number of significantly larger wildfires that are consuming more land than in previous years. This aligns with findings from a 2019 study by Natural Resources Canada, which highlighted a consistent increase in wildfire activity since the mid-20th century, driven by escalating temperatures and extended fire seasons.
The latest research, featured in the Canadian Journal of Forest Research, extends the analysis up to 2024 using advanced satellite mapping techniques and data from nine additional fire seasons, including the severe years of 2021, 2023, and 2024. The study demonstrates a continuous rise in the area burned by wildfires across nearly all eco-zones in Canada, including regions like the Pacific Northwest and Atlantic Canada that were historically considered lower risk due to wetter conditions but are now displaying stable or increasing fire trends.
Moreover, the study highlights a concerning shift towards larger fires accounting for a growing portion of the damage. While lightning remains a primary driver of wildfires, human-caused fires have been on the rise since the early 2000s, attributed not to policy failures but to the hotter and drier conditions that are making fire ignition more challenging to control.
Chelene Hanes, a research scientist at the Canadian Forest Service, emphasizes that the escalation in human-caused fires, especially the larger ones, is a result of drier fuel conditions. She notes that these large fires have reached a scale and intensity where traditional firefighting methods are limited, necessitating a focus on containment and protection rather than complete extinguishment. The impact of these significant wildfire events is increasingly visible on a national scale.
The changing wildfire landscape is also impacting Canada’s insurance industry, with rising wildfire risks reshaping losses, premiums, and long-term housing decisions nationwide. Insurance industry experts warn of a surge in natural disaster risk across the country, particularly in high-risk wildfire areas. Between 2005 and 2014, annual insurance losses from wildfires averaged around $70 million, but in the last decade, this figure has skyrocketed to approximately $750 million, signifying a significant increase in wildfire-related financial losses. Insurers are adapting by adjusting coverage pricing in highly exposed communities, potentially leading to higher premiums or policy modifications to manage overall risk effectively.
McGuinty, a vice-president at the Insurance Bureau of Canada, stresses the industry’s role in pricing risk and states that insurers have had to make adjustments in areas with heightened wildfire exposure. He reassures that wildfire coverage remains a standard inclusion in home insurance policies across Canada and emphasizes the availability of coverage despite the escalating risks, drawing a distinction with the situation in California where major insurers ceased underwriting policies in wildfire-prone regions after enduring substantial losses.
