Quebec Child Custody: A Parent's Guide

In short: Quebec is Canada's only civil-law province, and its family law reflects that: parental authority (autorité parentale) belongs to both parents jointly for as long as the child is a minor, no matter how custody is split, while custody (garde) is the separate, narrower question of where the child actually lives. Married couples divorcing use the federal Divorce Act; unmarried or separating-without-divorcing parents use Quebec's own Civil Code. Either way, Quebec courts decide the details based on the best interest of the child, with no presumption favoring one parent or one arrangement.

This is an educational overview written for parents, not lawyers. It isn't legal advice, and Quebec family law can turn on the specifics of your situation. For anything beyond general understanding, talk to a licensed Quebec family law lawyer or notary, or use the resources at Québec.ca: Separation and Divorce.

Autorité parentale vs. garde: the core distinction

Quebec's Civil Code draws a line that common-law provinces don't draw the same way.

Parental authority (autorité parentale) is the full bundle of rights and duties a parent has toward their minor child, education, health care decisions, religious upbringing, and general supervision of the child's development. Under article 600 of the Civil Code of Québec, the father and mother exercise parental authority together, and that stays true regardless of whether they're married, separated, divorced, or never lived together, and regardless of who has custody. Neither parent has a "veto" over the other, and separation alone doesn't strip either parent of it. A parent can only lose parental authority (déchéance) through a specific court process, typically involving serious circumstances.

Custody (garde) is narrower: it's about where the child actually lives day to day and who has physical care of the child. Custody can be:

• Garde exclusive (sole custody): the child lives primarily with one parent, with the other parent typically having access rights (droits d'accès).
• Garde partagée (shared custody): time is split between both parents' homes in some meaningful proportion, not necessarily an exact 50/50 split.

The key thing to understand: a parent without custody still has parental authority. Under article 605, that parent keeps the right to supervise the child's upbringing and to be consulted on important decisions, even if the child doesn't live with them day to day. Custody determines the address; parental authority determines who has a say in the child's life.

Federal Divorce Act vs. Quebec's Civil Code: which one applies

This split trips people up, so it's worth being explicit:

• Married and getting divorced? The federal Divorce Act applies to the divorce itself, and to parenting arrangements and child support tied to that divorce, uniformly across Canada. Since 2021 amendments, the Divorce Act uses "parenting time" and "decision-making responsibility" rather than "custody" and "access." A Quebec divorce judgment dealing with children may use this federal terminology.
• Unmarried, or separating without divorcing? Quebec's own Civil Code of Québec governs custody and parental authority. These proceedings use Quebec's civil-law terms, garde and autorité parentale, not the federal terminology.
• Family patrimony and property division specific to Quebec applies under the Civil Code regardless of which framework governs the custody question.

In practice, most Quebec custody matters (divorce or not) are heard by the Superior Court of Québec. Because Quebec keeps its own terminology for non-divorce matters while married couples encounter federal terms through their divorce, it's worth checking which framework your specific judgment falls under before assuming which words apply to your situation.

How Quebec courts decide

Whether under the Divorce Act or the Civil Code, the standard is the same: the best interest of the child, assessed case by case. Courts weigh factors like the child's age and needs, the existing relationship with each parent, each parent's ability to meet the child's needs and cooperate with the other parent, and the child's own views where age-appropriate. There's no legal presumption favoring either parent or favoring shared custody over sole custody, the arrangement follows what the specific child needs.

Parenting time and schedules

Quebec doesn't mandate one standard schedule. In practice, families and courts use arrangements similar to those seen elsewhere in Canada and the US:

• 2-2-3: frequent handoffs, often used for younger children
• Week on, week off: fewer handoffs, common for school-age children
• Garde exclusive avec droits d'accès: one parent has primary custody, the other has scheduled access, often alternating weekends

Moving with your child

If you want to relocate with your child and it would significantly affect the other parent's access or the terms of an existing judgment, Quebec courts weigh the reason for the move, the distance involved, the impact on the child's relationship with the other parent, and above all the child's best interest. A move that would meaningfully disrupt the current arrangement generally requires either the other parent's agreement or a new court order. See moving to another state with shared custody for the general best-interest framework that applies across jurisdictions, Quebec courts apply the same underlying logic through the Civil Code.

Changing an existing arrangement

Either parent can ask the court to modify custody or parental authority arrangements if circumstances have significantly changed. If both parents already agree on the change, Quebec's Homologation Assistance Service (Service d'aide à l'homologation, HAS) offers a lower-cost path, currently $325.50 per parent (indexed annually, free for parents eligible for legal aid) to turn an agreed change into a new court judgment without a fully contested hearing, available through legal aid offices.
