Ce que signifie ce calendrier pour la pension alimentaire pour enfants
On a day-count basis, the minority parent exercises 49.9% of parenting time — at or above the 40% threshold under article 9 des Lignes directrices fédérales sur la pension alimentaire pour enfants. This is an estimate only: courts have not settled on a single way to measure the 40%, and weigh the time a child is in a parent’s care and control (allocating sleep, school and daycare hours), with “no universally accepted method” (Froom v. Froom, 2005 ONCA 922) — overnights are a common proxy, but Ontario case law often prefers an hours-of-care-and-control measure. Where s. 9 is engaged, the court applies the Contino c. Leonelli-Contino, 2005 CSC 63 framework: each parent’s table amount is set off, then adjusted for the increased costs of shared parenting and the parties’ means and circumstances. The result is a discretionary range, not the full table amount.

Questions fréquemment posées
What is the 40% threshold?
Section 9 of the Federal Child Support Guidelines provides that where a spouse exercises a right of access to, or has physical custody of, a child for not less than 40% of the time over the course of a year, the court has discretion to depart from the standard table amount under s. 3.
How is parenting time counted?
The method of measuring the 40% is unsettled and fact-specific — there is "no universally accepted method" (Froom v. Froom, 2005 ONCA 922). Courts consider the time the child is in a parent's care and control, which means allocating sleep, school and daycare hours, not just counting overnights. Counting overnights and dividing by 365 is a common proxy, but Ontario case law often prefers an hours-of-care-and-control measure. This calculator counts days as an estimate; it does not determine which method a court will use.
What happens above 40%?
Once the 40% threshold is met, the court applies Contino v. Leonelli-Contino, 2005 SCC 63: (a) compute each parent's straight set-off table amount; (b) consider the increased costs of shared custody; (c) consider the conditions, means, needs and other circumstances of each spouse and child. The result is a discretionary range rather than a fixed amount.
What if it's very close to 40% (e.g., 39%)?
Courts generally treat the 40% threshold as a hard gate, but evidence-quality matters. If the calculation produces 39-41%, document overnights carefully — diaries, school pick-up records, calendar entries. Some courts have applied s. 9 below 40% where the access pattern was unique, but this is rare.
Does this affect the table amount even if I don't meet 40%?
No. Below 40% parenting time, FCSG s. 3 applies — the full table amount based on the payor's gross income, number of children, and province is presumptively payable. The s. 9 discretion only opens up at the 40% gateway.
