Yes. You must complete the Application for a Supplement for Handicapped Children form and return it to us. Be sure to provide all the documents requested. Part of the form must be completed by the health care professional (physician, physical therapist, psychologist, or other professional) who assessed or has treated the child and is most familiar with the child's condition.
Furthermore, to obtain the supplement for handicapped children, you and your spouse, if any, must file a Québec income tax return every year, even if one or both of you have no income to report. New arrivals in Québec may be required to provide a breakdown of income, or a Notice of Assessment issued by the Canada Revenue Agency, if they have not filed a Québec income tax return.
