Ticks & Lyme Disease

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. During the 2021 tick season, about 62% of the blacklegged ticks identified through active surveillance in this area were infected with Lyme disease bacteria.

These bacteria can be transmitted to humans after a blacklegged tick has fed for 24 or more hours.

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.
