Who is my Substitute Decision-Maker (SDM)?

  • In Ontario, everyone automatically has an SDM. The law (Health Care Consent Act) tells us who this would be.
  • For most people, their SDM will be their closest living relative. This category of SDMs appears in green in the image below.
  •  Others will have legally appointed SDMs. These are the ones in yellow. You will know if you have a legally appointed SDM because you would have had to complete a legal process (either forms or a court hearing).
  •  As a last resort, the Public Guardian and Trustee can act as your SDM if there are no relatives or legally appointed SDMs.
  •  Healthcare providers must get consent from the person who is highest on this list below.

What are the rules to be a Substitute Decision-Maker?

The SDM must be:

  • Willing to be your SDM and make decisions on your behalf if needed 
  • Available when decisions need to be made
  • Capable of providing consent
  • 16 years or older
  • Not prohibited by court order or separation agreement

Your SDM(s) should be someone who you feel would understand and honour your wishes

 

Other things you might want to consider when thinking about your Substitute Decision-Maker (SDM):

  • Can I talk with this person(s) about my wishes, values and beliefs?
  • Do I trust this person(s) to make decisions that reflect my wishes even if they disagree with them?
  • Can they make decisions under stress?
  • Can they communicate clearly with my health team in a stressful manner?It’s not always possible to know what kind of future health problems you may have.

  • Remember that if you have multiple SDMs at the same level, they will all need to agree on a decision. 

 

Tran is comfortable with her husband as her automatic SDM.

I would like to consider other options for my SDM

  • For some people, their automatic SDM is not the person they would like making their healthcare decisions.
  • In Ontario you can choose to legally appoint someone to make hour healthcare decisions instead of your automatic SDM. 
  •  This person is called an Attorney for Personal Care.
  • You may choose to appoint more than one person in this role.

Althea chose to appoint her two sisters as joint Attorneys for Personal Care instead of her mother who would be her automatic SDM.

Bob’s children do not get along. After reviewing the role of the SDM, he decides to appoint his middle son as Attorney for Personal Care.
