The General Rule, and Its Exception
Ontario family law generally recognizes that child support can continue past the usual age of majority where a child remains a "child" for support purposes under the applicable legislation — generally including situations where a child cannot withdraw from parental charge because of illness, disability, or another cause. See our guide to whether child support ends at 18 for the general rule this is an exception to.
What Can Generally Extend Support
Where a child has a disability that genuinely affects their ability to become financially independent, support can generally continue well beyond the age most support arrangements would otherwise end, sometimes indefinitely, depending on the nature and severity of the disability and the child's actual circumstances. This is generally assessed on the specific facts rather than through a fixed category or list, which is part of why it's worth discussing directly with a qualified professional rather than assuming either way.
How the Amount Is Generally Assessed
The amount of support in these situations can generally still reference the Child Support Guidelines table amounts, but may also be adjusted to reflect the child's actual needs and circumstances — including disability-related expenses, which can sometimes be addressed as special or extraordinary expenses on top of the table amount, depending on what the specific costs are and how they fit the recognized categories.
Other Resources That Can Factor In
Depending on the child's circumstances, other sources of support — such as provincial disability benefits, if the child becomes eligible as an adult, or other assistance programs — may also be relevant to the overall picture, though they don't automatically replace a parent's support obligation. How these pieces fit together is generally fact-specific, and worth discussing with a qualified professional given how much it depends on individual circumstances.
Frequently Asked Questions
Does child support automatically continue forever if a child has a disability?
Not automatically or universally — it generally depends on whether the child remains unable to withdraw from parental charge due to the disability, assessed on the specific facts, rather than applying to every situation involving a disability.
Is the support amount the same as for a younger child?
It can reference the same Child Support Guidelines table amounts as a starting point, but may be adjusted to reflect the child's actual needs, including disability-related expenses.
Can disability-related costs be claimed as special expenses?
Potentially, yes, depending on whether they fit the recognized categories under section 7 of the guidelines. See our guide to special and extraordinary expenses.
Does this apply only to physical disabilities?
Generally, no — the relevant legal concept is about a child's inability to withdraw from parental charge due to illness, disability, or another cause, which isn't limited to physical disabilities specifically.
What if my adult child's disability-related needs change over time?
Support arrangements can generally be revisited if circumstances change materially. See our guide to changing support for how that's generally approached.
