  • Since March 1, 2021, amendments to the federal Divorce Act — and, for Ontario, the Children's Law Reform Act (CLRA) — retired "custody" and "access" from family law.
  • Notice what didn't change: the underlying legal test.
  • Relabelling "custody" as "decision-making responsibility" doesn't automatically shift who holds authority over what, and it doesn't change how a court weighs a case.

If you separated years ago, your court order probably says "custody" and "access." If you're separating now, a lawyer will talk to you about decision-making responsibility, parenting time, and contact instead. It's the same general subject — who decides what for your kids, and who has them when — but different words, and that shift can be confusing if nobody explains why it happened.

The short version: Ontario didn't invent new legal concepts out of nowhere. Federal and provincial lawmakers replaced adversarial-sounding language with terms that describe what actually happens day to day. Here's what changed, when, and whether it affects a case that's already underway.

When and Why the Language Changed

Since March 1, 2021, amendments to the federal Divorce Act — and, for Ontario, the Children's Law Reform Act (CLRA) — retired "custody" and "access" from family law. In their place: "decision-making responsibility," "parenting time," and "contact."

The reasoning was about tone as much as substance. "Custody" and "access" carried a winner-and-loser feel, as though one parent had the child and the other merely visited. Family law practice had already moved away from thinking in those terms; the vocabulary just hadn't caught up. The new terms describe roles and time rather than who came out ahead.

Old Term vs. New Term

Old termNew termWhat it actually covers
CustodyDecision-making responsibilityAuthority over significant decisions for a child: health care, education, religion or culture, and significant extracurricular activities
AccessParenting timeTime a child spends in a parent's care, including the day-to-day and emergency decisions made during that time
Access (for a non-parent)ContactTime a non-parent — commonly a grandparent — spends with a child under a contact order

Notice what didn't change: the underlying legal test. Courts still decide these questions using the best-interests-of-the-child test, and that test wasn't rewritten by the terminology update.

Does the New Wording Actually Change What You Get?

Not by itself. Relabelling "custody" as "decision-making responsibility" doesn't automatically shift who holds authority over what, and it doesn't change how a court weighs a case. What matters is still the specific arrangement — who holds decision-making responsibility, and how parenting time is divided — not which word describes it.

A few things worth knowing about what stayed the same:

What Happens to Older Orders That Still Say "Custody"

An order made before March 1, 2021 that uses "custody" and "access" doesn't become invalid just because the vocabulary changed. Courts, lawyers, and the Family Responsibility Office continue to interpret and enforce those orders on their original terms. That said, if you go back to court to vary an existing order — through a motion to change, for example — expect the updated order to use the current terminology, even where the underlying arrangement stays largely the same.

The New Terms, In Practice

Frequently asked questions

Do I need to go back to court just to update the wording in my old order?

No. Wording alone isn't a reason to reopen a valid order. Courts generally only revisit an order's terms when there's a substantive reason to vary it, not simply to modernize its language.

Is "decision-making responsibility" the same thing "sole custody" used to describe?

Not exactly. It describes the same general idea — holding authority over major decisions — but the term itself is broader and doesn't carry the same all-or-nothing framing "custody" sometimes implied in practice.

Can grandparents still ask for time with a grandchild under the new terms?

Yes. That's specifically what "contact" and a contact order are for: time with a child granted to someone other than a parent.

Does using the new terminology change how child support is calculated?

No. Child support is assessed separately, using income-based guideline tables, and isn't affected by which parenting terminology applies in your case.
