Ticks and Lyme disease

Lyme disease is a serious illness caused by the bite of an infected blacklegged tick. Ticks are small, ranging from the size of a poppy seed to a pea. The size of the tick varies depending on its age and whether it has fed recently. The bite is usually painless so you may not know that you have been bitten. It is important to be on the lookout for ticks and the symptoms of Lyme disease.

In Quebec, available data confirms the presence of established Borrelia burgdorferi-positive Ixodes scapularis tick populations, particularly in the following areas:

  • A large part of Montérégie
  • The south-east portion of the Mauricie- and Centre-du-Québec region
  • The north and west of Estrie

As such, Canadians are encouraged to take preventive measures to reduce their risk when spending time in areas where there may be ticks.
