Who can be detained in hospital

Under the Mental Health Act (MHA), a youth, adult or senior may be detained for observation, examination, assessment, treatment, and care if they:

  • require intensive, long-term and more comprehensive mental health services and supports, and
  • meet the certification criteria for the issuance of admission or renewal certificates under the MHA

A person who is assessed by doctors who determine the person meets these criteria, may be held in hospital against their will. This is referred to as being ‘detained’.  

Patients may be detained in a designated facility for up to 24 hours under either: 

  • form 1 admission certificate
  • form 4 certificate of transfer into Alberta
  • form 8 warrant,
  • form 9 extension of warrant
  • form 10 statement of peace officer on apprehension

Patients who are under 2 admission certificates or 2 renewal certificates are referred to as ‘formal patients’ under the act. They may be detained for a period of 1 month from the date the second admission or renewal certificate is issued. If a patient is under a third or subsequent set of renewal certificates, the period of detention is not more than 6 additional months.

Certification criteria

The criteria for the issuance of a certificate are that the person:

  • is suffering from mental disorder
  • has the potential to benefit from treatment for the mental disorder
  • is within a reasonable time, likely to cause harm to the person or others or to suffer substantial mental or physical deterioration or serious physical impairment
  • is unsuitable for admission to a facility other than as a formal patient, as a result of or related to the mental disorder, and
  • is unsuitable for admission to a facility other than as a formal patient


A doctor is assigned to provide care for the patient while they are in hospital. The doctor leads a multidisciplinary team of health professionals who care for and support the patient in their journey of recovery. The doctor makes decisions about the patient’s privileges and discharge planning and makes treatment recommendations.

Either the patient or the substitute decision-maker provides consent for treatment. In some cases, under certain conditions, the Review Panel may order treatment.


Who you can talk to

If you have important information you want to share with the treatment team, or have questions, you should speak with the patient’s doctor or nurse. 

If you have further questions or concerns, you may contact our office to talk with an Advocate representative.

Patient rights

Patients detained in hospital under 1 or 2 admission certificates, or community treatment orders, have many rights.

  • the patient's nearest relative, unless the patient being discharged objects
  • the patient's family doctor, if known, along with the discharge summary, including any recommendations for treatment per section 32(1)(c) of the Mental Health Act
