Wildfire causes in Canada
Canadian wildfire agencies do not use one set of cause terms. FireRadar keeps the suspected-cause wording from each official source and shows where cause data is available. Records are not forced into a national lightning-versus-human total.
Current cause data unavailable
We cannot currently confirm the latest cause information. FireRadar does not report zero when source data is unavailable.
What this page can and cannot tell you
Suspected is not necessarily final. Current incident records can use preliminary cause labels while an investigation continues. A final annual dataset may later classify the same event differently.
Missing does not necessarily mean unknown. It means the official record available to FireRadar does not currently include a usable cause value.
Source vocabularies are not interchangeable. Terms such as Person, Human, Natural, Lightning, Under Investigation, or agency-specific subcategories are not silently merged here.
Why there is no national lightning-vs-human pie chart
Current records do not support a reliable national percentage because cause coverage is incomplete and agency categories differ. FireRadar will publish national cause trends only when official historical data supports a documented, reproducible comparison.
