"Where the vast majority of the Canadian population lives, which is near the American border, are all in areas that are already climatically suitable for tick populations," said Katie Clow, an assistant professor in the department of population medicine at the University of Guelph. "Likely, the invasion process is just going to continue to sort of fill that ecological niche." Clow says parts of southern Canada that do not yet have ticks will likely see them emerge over the coming decade.
