Hearing – For the disability amount, you are markedly restricted in hearing if, all or substantially all the time:

  • you are unable to hear so as to understand another person familiar with you, in a quiet setting, even with appropriate devices; or

Inordinate amount of time – Examples of how you might take an "inordinate amount of time" to perform a basic activity of daily living:

  • You can walk 100 metres (or approximately one city block), but only by taking a significant amount of time, stopping because of shortness of breath or because of pain, all or substantially all the time.
  • When speaking, you must repeat words and sentences several times, and it takes a significant amount of time for you to make yourself understood.

Life-sustaining therapy – Life-sustaining therapy is therapy you need to support a vital function. You need to dedicate time specifically for this therapy at least three times per week, for an average of at least 14 hours per week. Eligibility for the disability amount under life-sustaining therapy applies only to 2000 and later years.

Activities such as following a dietary restriction or regime (including carbohydrate calculation), exercising, traveling to receive the therapy, attending medical appointments (other than appointments where the therapy is received), shopping for medication, or recuperating after therapy are not included in the time counted towards therapy. Also, if you receive therapy by a portable device, such as an insulin pump, or an implanted device, such as a pacemaker, the time the device takes to deliver the therapy does not count towards the 14-hour requirement. However, the time you spend setting up a portable device does count.

Examples of life-sustaining therapy include chest physiotherapy to help in breathing, kidney dialysis to filter your blood, and for 2005 and later years, insulin therapy to treat Type 1 diabetes in a child who cannot independently adjust the insulin dosage.

Markedly restricted – You are markedly restricted if, all or substantially all the time, even with therapy (other than life-sustaining therapy) and the use of appropriate devices and medication, either:

  • you are unable to perform a basic activity of daily living; or
  • it takes you an inordinate amount of time to perform a basic activity of daily living.

Mental functions necessary for everyday life – For the disability amount, you are markedly restricted in the mental functions necessary for everyday life if, all or substantially all the time:

  • you are unable to perform the mental functions necessary for everyday life, by yourself, even with appropriate therapy, medication, or devices; or
  • you require an inordinate amount of time to perform the mental functions necessary for everyday life, by yourself, even with appropriate therapy, medication, or devices.
