This graph illustrates the percentage of honeybee colonies lost during the winter in Ontario from 2012 to 2024. The data, primarily sourced from annual surveys by the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) and the Ontario Beekeepers' Association (OBA), reveals a volatile and often alarmingly high trend. The dotted line represents the 15% loss rate that was historically considered acceptable by beekeepers.
Data compiled from OMAFRA, OBA, and CAPA annual reports.
