Ixodes scapularis ticks submitted through passive surveillance infected with Borrelia burgdorferi, Canada, 2020^a,b

^a Each dot represents the probable location of acquisition of at least one I. scapularis (n=860) single or multiple tick submission submitted through passive surveillance that was infected with B. burgdorferi. Eight ticks were not mapped because the probable location of acquisition could not be determined

^b Lyme disease risk areas are identified by the provinces as of 2021 using the methods described in the 2016 national Lyme disease case definition ((22)). On the map, risk areas are identified as hatched gray areas
