Lyme Disease in Canada

The Ontario government published information, e.g.,

How do ticks transmit Lyme disease?

Blacklegged ticks are the only type of tick in Ontario that can consistently transmit Lyme disease. Even with a bite from an infected blacklegged tick, there is only a small chance of getting Lyme disease. Ticks feed on blood by inserting their mouthparts (not their whole bodies) into the skin of a person, or an animal. Ticks feed slowly and their body gradually enlarges as it feeds, making it more visible. It usually takes from 3 to 7 days for a blacklegged tick to take a complete blood meal.
Ticks are most likely to transmit infection after being attached for more than 24 hours of feeding because the bacteria requires time to migrate from the tick’s gut to its salivary glands. Because of this delay, prompt detection and removal of ticks is one of the key methods of preventing Lyme disease.
