Child Support in Canada

What is this right?
Both parents are financially responsible for their children — that's the foundational principle. The Federal Child Support Guidelines turn it into numbers: standard amounts based on the payer's income and the number of children.
The tables get refreshed by the Department of Justice periodically — always check the current version at justice.gc.ca. On top of the table amount, parents share section 7 expenses — daycare, medical costs, education, extracurriculars — in proportion to their incomes.
The single most important legal point about child support: it is the child's right, not the other parent's. It cannot be waived by agreement. A "we agreed to no support" clause has no legal effect, full stop. Support continues until the child turns 18, or longer if the child remains dependent — full-time post-secondary, or living with a disability.
One narrow carve-out: if the payer earns under $16,000 per year, there's no table obligation.
When does it apply?
Child support kicks in when:
- Parents separate or divorce and have children under 18 (or older but dependent).
- The rule covers married and common-law parents alike.
- The payer is usually the parent with less parenting time.
What to Do If the Other Parent in Canada Refuses to Pay Child Support
- Pull the table amount at justice.gc.ca using your income and number of children.
- Identify section 7 expenses and split them by income share.
- Exchange full financial disclosure — tax returns, pay stubs, notices of assessment.
- Lock the amount in a written agreement or court order. Verbal arrangements unravel.
- Review whenever income changes materially. Both sides have skin in keeping the number current.
What should you NOT do?
- Don't stop paying without a court order — even if you're being denied parenting time. The two are legally separate, and self-help loses.
- Don't hide income. Courts can impute income based on capacity, and they're getting better at it.
- Don't try to waive support. The waiver isn't enforceable.
- Don't assume support ends at 18. It continues for full-time students and dependent adults.
- Don't pay informally without records. Proof of every payment matters; cash without receipts is the same as not paying.
