Enter your actual annual overnight counts to see your parenting time split — and whether it meets the 40% shared custody threshold under the Federal Child Support Guidelines.
Estimate only — not legal advice. Custody terminology in Ontario has shifted to "decision-making responsibility" and "parenting time."Section 9 of the Federal Child Support Guidelines applies once a parent has at least 40% of overnights, changing how support is calculated.
Under s.8, if you have multiple children and each parent has majority residence of at least one, support is calculated as a set-off between each parent's Table amounts.
Since 2021, Ontario law uses "decision-making responsibility" and "parenting time" instead of "custody" and "access" — though the concepts remain similar.
Once you know your time share, use our Child Support Calculator to estimate the resulting support obligation.
