Life-event navigator · Turning 18
Your child is turning 18. Here is everything that changes, and exactly what to do next.
Turning 18 is when many child disability programs end or change and adult income, health, and service paths open. This navigator organizes what to review before, during, and after the birthday so families can plan without hunting department by department.
Verified sources, provincial guidance, official links, and a printable checklist in one place.
Before 18
- List child programs and age cutoffs; renew DTC if certification expires soon.
- Start provincial adult disability or developmental services intake where waitlists apply.
- Confirm health card, drug plan, and who can sign medical and benefit forms.
- Review guardianship or supported decision-making if the young adult will need help signing.
After 18
- Apply for or confirm Canada Disability Benefit with valid DTC (ages 18 to 64).
- Connect to provincial disability income or employment supports if needed.
- Track RDSP grants and bonds; grants can continue to age 49 while DTC is valid.
- Re-run the benefits quiz with updated age and disability answers for province-specific results.
See also Benefits over your life (around 18) for a broader age-based map.
