ADP : Teletypewriters for the Deaf (TTY's) and
Speech Impaired
Printable version

What kind of TTY's does the Assistive Devices Program (ADP) cover ?

Various models are covered by ADP. So are various flashing signaling devices to accompany them, for deaf persons only.

Who can apply ?

Any resident of Ontario who cannot communicate by regular phone because of :

  • severe hearing loss or
  • impaired speech

and requires the use of a TTY for six months or longer. You must be eligible for Ontario Health Insurance and have a valid Health Card in your name.

ADP does not pay for equipment available under the Workplace, Safety and Insurance Board or to Group 'A' veterans for their pensioned conditions.

What do I do first ?

You begin by getting an ADP Equipment/Supply Authorization form.

You can get this form from an authorizer or vendor registered with ADP or by calling :

Toronto :   416-327-8804
Toll Free :   1-800-268-6021
TTD/TTY :   416-327-4282
TTD/TTY Toll Free :   1-800-387-5559

Do I fill in the entire ADP form ?

No. You fill in only the first part called Biographical Information.

Do I need a medical check-up ?

Not necessarily. If you have a hearing loss, you may see :

  • your family doctor, or
  • a specialist such as an otolaryngologist, or
  • an audiologist registered with ADP as an authorizer.

The doctor will fill in the second part of your ADP form.

The doctor or ADP registered audiologist authorizer will sign the third part of the form after writing :

"I hereby certify that the above-named person has a hearing loss severe enough to impede normal use of the telephone even with the use of a hearing aid and a voice amplified telephone, and requires the use of a TTY on a long-term basis."

What do I do if I have impaired speech ?

If you can hear but have impaired speech, you should contact a speech-language pathologist registered with ADP. He or she will sign the third part of the form after writing :

"I hereby certify that the above-named client has a speech impairment severe enough to impede normal use of the telephone even with the use of an augmentative communication aid and requires the use of a TTY on a long-term basis."

Where can I get my TTY and flashing signaling device ?

From any vendor who is registered with ADP and sells these products. The vendor bills ADP for 75 per cent up to a maximum of $400 of the cost of the TTY and 75 per cent up to a maximum of $75 of the cost of the flashing signaling device.

If you are receiving benefits from any of the following: Assistance to Children with Severe Disabilities; Ontario Disability Support Program; or Ontario Works, at the time your TTY and flashing signaling device are authorized, the vendor may bill ADP up to $533.33 toward the cost of your TTY and up to $100.00 toward your flashing signaling device. You pay the vendor the remaining cost. Ask your registered vendor for more details.

What if I need to replace my TTY or flashing signaling device ?

ADP will contribute to a replacement once every five years if the original device is no longer working and cannot be repaired at a reasonable cost.

ADP does not pay for replacement during those years if the original equipment is lost, stolen or damaged due to misuse.
