Ticks of Ontario

In Ontario, the blacklegged tick (deer tick) is of particular concern, as it can transmit Lyme disease. These ticks are most active in the spring and summer but can be found year-round when temperatures are above freezing. To prevent tick bites, wear light-colored clothing, use insect repellent, and check for ticks after being outdoors.
