There are different provincial things for community treatment--civil orders--to get someone with a mental illness who needs treatment, but doesn't recognize that they need treatment, to remain in treatment. This is usually for people with schizophrenia or related illnesses who need anti-psychotic medications. They can often be delivered injectably every two weeks. But if they exist, most of the community treatment provisions are weighted towards the rights of the person with the illness and not weighted very well towards the interests of the person's family, or the people who actually can see that the person is ill, or in fact the community if the person has been committing offences against the community.
