^a Each dot represents the probable location of acquisition of at least one I. pacificus (n=2) or I. scapularis (n=1,819) single or multiple tick submission submitted through passive surveillance that was infected with B. burgdorferi

^b Lyme disease risk areas are identified by the provinces as of 2020 using the methods described in the 2016 national Lyme disease case definition (28))))
