Process Description

Step 1: Is the person capable to consent to the health treatment being proposed at this time?

A) Able to understand information that is relevant to making a decision about the treatment
B) Able to appreciate the reasonably foreseeable consequences of a decision or lack of decision

  • If unsure, proceed to Step 2
  • If no to A and B, the person is deemed incapable. Proceed to Step 3
  • If yes to A and B, the person is deemed capable. Proceed to Step 8

Step 2: Gather additional information

If you are unsure, you cannot make a decision at this point.

  • Gather additional information and consult with others as appropriate and go back to Step 1.

Step 3: Inform person

Inform the person that a substitute decision-maker (SDM) will make decisions on their behalf.

  • Does the person request a review of the finding of incapacity?
    • If yes, go to Step 4
    • If no, go to Step 5

Step 4: Assist the person in making an application to appeal

Assist the person in making an application (for an appeal) to the Consent and Capacity Board (CCB)

A decision will be made by the CCB regarding a person’s capacity to consent to treatment being proposed at this time.

  • Is the person capable?
    • If no, proceed to Step 5
    • If yes, proceed to Step 8

Step 5: Is the highest ranking SDM available to make decisions for the person?

Is the highest ranking substitute decision-maker* (from the Health Care Consent Act's Hierarchy of Substitute Decision-Makers) available and willing to make decisions for the person?

*If there are multiple substitute decision-makers (SDMs) of equal ranking, then the health practitioner may suggest to the group to collectively make a decision or appoint one individual to be the lead in communicating with the health practitioner (as it applies within the practice setting).

  • If no, proceed to Step 6
  • If yes, proceed to Step 7

Step 6: Consult with PGT

Consult with the public guardian and trustee (PGT) regarding treatment as a decision maker of last resort.

  • If yes, proceed with the treatment.
  • If no, do not proceed with the treatment.

Step 7: Receive informed consent from the SDM

Has informed consent been received from the substitute decision-maker (SDM)?

  • If no, do not proceed with treatment.
  • If yes, proceed with treatment.

Step 8: Receive informed consent from the person

Has informed consent been received from the person?

  • If no, do not proceed with treatment.
  • If yes, proceed with treatment.
