The Public Health Agency of Canada (PHAC) monitors tick-borne diseases in Canada using a One Health approach. Ticks are usually active in Canada between spring and fall. This dashboard provides the recent and historical data for human cases reported by provinces and territories to the PHAC.
About One Health
PHAC uses a One Health approach, which recognizes the interdependence of human health, animal health and their shared environment. Vector-borne diseases are increasing due to warmer temperatures and range expansion of mosquito and tick habitats.
