Assessing the Capacity to Make Decisions

Page Contents

Capacity Assessment is the formal assessment of a person's mental capacity to make decisions about property and personal care. Many situations require capacity assessments to be conducted by specially qualified assessors who must follow specific guidelines.

This page contains information and resources for assessors as well as those who are requesting a capacity assessment.

I'm concerned about someone's well-being. What do I do?

If you know of an adult who appears to be mentally incapable and at serious risk, contact the Office of the Public Guardian and Trustee (OPGT).

If it appears that a person is mentally incapable and at serious risk of harm, the OPGT will conduct an investigation if no alternative solution can be found.

It is important to note that this is not an immediate, emergency crisis response service. If you are in a crisis or can't wait for an appointment, go to the emergency department of a nearby hospital. The OPGT has no authority to make decisions for the person during an investigation or while the matter is before the courts.

For more infomation, read the "Frequently Asked Questions" about Guardianship Investigations.
