In 2017, the Pet Tick Tracker received over 1500 submissions! We have compiled the information below. 

Before you view the maps, here are some details about how the maps were created, and what you should consider as you interpret the data:

  • Species identification for each tick specimen was not validated. Therefore, the accuracy of species identification is based on the submitter's skill level.

  • Geographic location of acquisition is based on submitter recall (and sometimes it's not reliable because we just don't know where a tick was picked up!).

  • Number of submissions are highly influenced by population density and interest / awareness of the public. We received many more submissions from Southern Ontario, which may be a reflection of both population density and interest and not necessarily tick populations. 

  • Data are classified based on the centroid of the postal code provided. If only the first three characters were provided, then data was classified based on the centroid of the FSA (forward sortation area).

  • Maps were prepared showing all ticks species, blacklegged ticks, American dog ticks and lone star ticks. Other species of ticks were submitted in much lower numbers. 

All ticks submitted from Eastern Canada, 2017

All ticks submitted from Western Canada, 2017

All ticks submitted from Southern Ontario, 2017

Blacklegged ticks (Ixodes scapularis) submitted from Southern Ontario, 2017

American dog ticks (Dermacentor variabilis) submitted from Southern Ontario, 2017

Lone star ticks (Amblyomma americanum) submitted from Southern Ontario, 2017

Data for the base vector layers were accessed from Statistics Canada (www.statscan.gc.ca) and Scholars Geoportal at University of Guelph. 


In 2016, Dr. Scott Weese of the Ontario Veterinary College launched the Pet Tick Tracker to help monitor changes in tick populations. Through this online tool, pet owners could submit reports of tick findings - and the response was overwhelming! He's now teamed up with Drs. Katie Clow and Michelle Evason to create Pets and Ticks - a comprehensive website that brings the Pet Tick Tracker together with up-to-date, evidence-based information on ticks in Canada.
