In the case of Lyme disease, a 'vector' is the term used to describe a tick species that can transmit (pass) Lyme disease through a bite. Blacklegged ticks are capable of transmitting Lyme Disease in Ontario. Other 'non-vector' ticks cannot transmit Lyme disease. View the Lyme Disease web page for more information.
