Hi Little Sister,
I'm going to suggest you contact the family support educators who work for the BC Schizophrenia Society. They will know what kinds of income and other supports are likely to be available to your brother. You want to contact the one that works in the town your brother lives in. http://www.bcss.org/category/branches/
You can also call HealthLinkBC at 811 to ask what kinds of supports and programs might be available for people with schizophrenia in the town where your brother lives.
Does anyone else have some experience to share?
