If you need to call, please leave a detailed message with your name, telephone number, and the reason for your call, and we will get back to you at our earliest convenience. Please note that you may not receive a call back for several days or more.


We apologize for any inconvenience this may cause and appreciate your understanding during this time.

  • Routine infant immunizations for those 2-18 months of age without a health care provider
  • Children under 5 for flu (influenza) immunizations

Appointments are required to provide a safe environment for clients and staff. Walk-in services will not be available. Please call us at 625-5900 to book an appointment.

    Whooping Cough Protection with a Pertussis Vaccine 

    Calling all adults - consider getting a whooping cough (pertussis) booster, especially if you have infants in your personal or work life.Whooping cough can affect any age but is most serious for young infants under four months of age who don't have full protection as they haven't completed the pertussis vaccine series which is given at 2, 4, 6 months and an 18 month booster. Two more boosters are given; between ages 4 and 6 and 14 and 16. 

    Adults can help protect infants by making sure they get a pertussis booster. All adults in Ontario are recommended to receive one FREE pertussis-containing Tetanus/Diphtheria (Tdap) booster over the age of 19 years when they get their Tetanus/Diphtheria (Td) booster. The Td booster is recommended every 10 years.

    Talk to your health care provider or call a TBDHU nurse at 625-5900 or Toll-Free 1-888-294-6630. The vaccine is available at the Wednesday clinic and is also available from health care providers.

    The Health Unit does not provide Tuberculosis (TB) skin tests (also called TST) for screening purposes for school or employment. TB skin testing is only available to those who have been identified by the Health Unit as a contact of someone who has TB. Visit TB page for more information
