Tick Population Growth in Canada

The tick population in Canada, particularly the black-legged ticks or Ixodes scapularis, has significantly increased over the past decade. Previously, tick issues were more isolated, but now, especially in southeastern parts of Canada, tick populations have surged. Factors like climate change have contributed to this growth, with warmer temperatures accelerating tick development and reproduction, leading to a rise in tick-borne illnesses.
