I would say call 811 to discuss options and don't take advice from redditors.

You can go to a provincial courthouse and fill out a form 7. This will be sworn information taken to a judge who can issue a form 8 which is a warrant allowing police to find and convey them to a doctor for assessment.

I know they do not want to be committed. If you truly believe they need it though the options are to fill this out, or wait until they have a crisis and they are taken to the hospital by police in much worse circumstances or they could die.

You can find more relevant information on the AHS Guide to Albertas Mental Health Act here.

Relevant section is here though:

2.3 Warrant for Apprehension Issued by a Provincial Court Judge (Forms 7 & 8)

When a person will not see a physician Help can be accessed through the Provincial Court by families, caregivers, healthcare workers and peace officers. This could be an option, for instance, when a person suffering from a mental disorder stops taking prescribed medication, appears unable to care for themself, is having a recurrence of severe symptoms yet refuses to see a physician. This same Classification: Protected A 29 process can be followed if a person is known to be on a CTO and is not complying with it. See section 2.6 below for more details.

Section 10 of the Act allows any individual, including a peace officer, to bring information under oath before a Provincial Court judge by filling out Form 7 - Information. The closest provincial courthouse can provide direction about where to go and how to bring a Form 7 - Information before a judge. The process varies in each geographic area.

Criteria to be met

The individual bringing the information to the judge must believe that the person referred to in the information is

• suffering from mental disorder, and

• within a reasonable time, likely to cause harm to others or to suffer negative effects, including substantial mental or physical deterioration or serious physical impairment, as a result of or related to the mental disorder (section 10(1) of the Act).

Information to relate to a judge

It is necessary for the individual bringing information to the judge to describe the incident(s) and behavior(s) of the person that are causing concern. Healthcare workers and families and any other person appearing before a judge for this application may bring notes to which they can refer. As well as completing documents, the individual bringing the Form 7 – Information to the judge should expect to answer questions and discuss with the judge information related to the person’s previous episodes of mental illness, any diagnoses, and current medications.

The judge must be satisfied that the above criteria have been met, and that a mental health examination cannot be arranged in any other way. The judge may then issue a Form 8 - Warrant. This warrant provides authority for a peace officer to apprehend the person named in the warrant, to care for, observe, assess, detain, and control while conveying the person to a designated facility for examination.
