Ontario legal and future-planning guide
Start by identifying the specific decision where support is needed. Many autistic adults have legal capacity, and capacity is decision-specific. Consider rights-preserving support before any court process that would remove decision-making authority.

At age 18, your child becomes a legal adult under Ontario law. This is a significant transition that many families are unprepared for. Understanding what changes, and what does not, is the foundation of future planning.
Key principle: Many autistic adults have full legal capacity and can make their own decisions with or without support. Capacity is decision-specific, not all-or-nothing. A person may have capacity to decide where to live but need significant support managing finances. The law recognizes this nuance.
Supported decision-making is an internationally recognized framework, aligned with the UN Convention on the Rights of Persons with Disabilities (which Canada has ratified) and supported by disability rights organizations in Ontario. Ontario does not yet have dedicated SDM legislation, but SDM can be used in practice and courts increasingly recognize it as a less restrictive alternative to guardianship. It preserves autonomy while providing structured support.
A support network of trusted people (family, friends, professionals) who help the person understand information, consider options, and communicate decisions. The decision belongs to the person, supporters facilitate, not substitute.
Supporters can help interpret complex documents, attend medical appointments to take notes and ask questions, assist with financial management while the person retains signing authority, and communicate preferences on behalf of the person.
OSDM (osdm.ca) provides resources, templates, and guidance for setting up supported decision-making arrangements in Ontario. They offer workshops and direct support to families and self-advocates.
If your adult child is assessed as lacking legal capacity for a specific type of decision, and no supported decision-making arrangement can adequately address their needs, guardianship may be considered, as a last resort, and only for the decisions where capacity is absent.
Guardianship is a court-ordered legal arrangement that removes a person's right to make their own decisions in specified areas (personal care, property, or both). It is the most restrictive option and should only be pursued when less restrictive alternatives, including supported decision-making, have been genuinely considered and found insufficient.
Financial planning for a child with a disability requires specialized tools that protect both your child's eligibility for government supports and their long-term financial security.
A trust designed to hold assets for a person with a disability without disqualifying them from ODSP. The trustee has full discretion over distributions, meaning assets are not counted as personal property of the beneficiary. Must be established by a lawyer with special needs planning experience. Typically funded through a will.
A federal tax-sheltered savings plan for Canadians who qualify for the Disability Tax Credit. The government adds Grants (up to $3,500 annually) and Bonds (up to $1,000 annually; confirm current limits with ESDC) based on family income. Money grows tax-free; withdrawals are taxed in the recipient's hands (usually at low rates). One of the most powerful financial tools available for disability planning.
A personal document (not legally binding) that communicates your child's personality, preferences, daily routines, relationships, likes and dislikes, and your wishes for their future care. Written for future caregivers and trustees. Invaluable for ensuring continuity of person-centred care.
Future planning is most effective when begun early, ideally when your child is in their early teens. This allows time for thoughtful decision-making, proper legal drafting, and gradual transition rather than crisis-driven choices.
