Ticks are Present in Thunder Bay and District
The City of Thunder Bay and immediately surrounding area are considered a risk area for Lyme disease.
Lyme disease is caused by a bacterium called Borrelia burgdorferi, which is spread through the bite of infected blacklegged ticks. Infected blacklegged ticks need to be attached for at least 24 hours in order to transmit the bacteria that causes Lyme disease.
Most ticks found in the Thunder Bay District are wood ticks and do not carry the Lyme disease bacteria. Visit our Lyme Disease fact sheet page for more information.
