Estate Planning for Young Parents in Ontario

The 5 things every parent of young kids needs to put in place — and why a will is only the start.

Last reviewed 2026-06

The 5 things every parent of young kids needs to put in place — and why a will is only the start.

Who this is for: Parents in Ontario with children under 18 (or kids with disabilities of any age) who want to make sure their children are cared for, and provided for, if something happens to one or both parents. What you'll get: a plain-language explanation of the five pieces that matter most — guardianship, a trust, your trustee, life insurance, and your own powers of attorney — plus a checklist and a short FAQ.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

Most young parents put off estate planning because it feels morbid, expensive, or like something for people with "estates." But for parents, this isn't really about money — it's about who raises your kids and how the money you leave behind reaches them without being handed over the moment they turn 18. Those two questions don't answer themselves, and the law's default answers are rarely the ones you'd choose.

Here are the five things to understand.


1. Naming a guardian for your children

This is the reason most parents finally sit down to write a will, and rightly so.

In Ontario, you cannot permanently appoint a guardian of your child in your will — only a court can make a permanent guardianship order, because the court must consider the child's best interests at the time. But the law (the Children's Law Reform Act) lets a parent name a guardian in their will who can take over care temporarily, generally for a set period after the parent's death, while that person applies to the court for permanent custody (now called decision-making responsibility).

💡 Think of it this way: your will doesn't hand over your child like a possession. It tells the court — clearly and in your own voice — who you trust, and it gives that person the legal standing to step in immediately and then ask a judge to make it permanent. Courts give real weight to a parent's stated wishes.

What this means in practice:

⚠️ Watch out: the period for which a will-based appointment lasts, and the exact court process, are set by statute and the Family Law Rules, and they can change. Confirm the current rules with an Ontario lawyer when you sign — don't rely on a figure you read online.


2. Setting up a trust so your kids don't inherit a lump sum at 18

Here's the surprise that catches most parents off guard: in Ontario, a child is entitled to receive their full inheritance outright at age 18 unless your will says otherwise.

Picture a life insurance payout, the sale of the family home, and your savings all landing in your 19-year-old's bank account at once. Few 18- or 19-year-olds are ready to manage a large sum responsibly, and an outright gift gives them no protection from poor decisions, predatory relationships, or their own inexperience.

The fix is a testamentary trust — a trust created by your will that takes effect when you die. Instead of the money going to your child directly, it's held by a trustee who manages and pays it out according to the rules you set.

You decide the terms. Common approaches include:

💡 A trust isn't just for the wealthy. Even a modest estate plus a life insurance policy can add up to a meaningful sum — exactly the amount you'd not want handed to a teenager in one cheque.

A special note on children with disabilities: if a child receives provincial disability support (such as ODSP), an outright inheritance can disqualify them from benefits. A specially drafted trust — often called a Henson trust — can hold funds for their benefit without affecting eligibility. This is technical and the rules change; get tailored legal advice.


3. Choosing a trustee (and a guardian who isn't necessarily the same person)

Your trustee is the person — or trust company — who holds and manages the money for your children until the trust ends. This is one of the most important and most overlooked decisions in the whole plan.

Look for someone who is:

You can name co-trustees (two people who must agree) for accountability, or appoint a professional trustee (a trust company) for larger estates, though they charge fees set by law and agreement.

💡 Splitting the roles is normal and often wise. The aunt who would lovingly raise your kids may not be the person you'd trust to invest a six-figure trust for two decades. You can name her as guardian and name a different, financially capable person as trustee. They work together: she raises the children, he funds that care from the trust.

Always name an alternate trustee in case your first choice can't or won't act.


4. Life insurance and beneficiary designations — why a minor can't just "get the money"

Life insurance is the engine of most young families' estate plans: it converts a modest income into a meaningful sum exactly when your family needs it most. But how you name the beneficiary changes everything.

The trap: if you name a minor child directly as the beneficiary of a life insurance policy (or an RRSP, TFSA, or pension), the insurer or institution generally cannot pay the money to the child, because a minor can't give a valid receipt. Without planning, the funds may be paid into court or require a court-appointed guardian of property to manage — a slow, costly, supervised process, with the money still released outright at 18.

Better options:

⚠️ Watch out: review your beneficiary designations after every major life event — marriage, separation, a new child. An ex-spouse named on an old policy generally still collects unless you change it. Insurance and pension rules are technical; confirm the right wording with a lawyer or advisor.

RESP considerations. A Registered Education Savings Plan is your asset (the subscriber's), not the child's, so it doesn't automatically continue if you die. Decide who should take over as subscriber and make sure your will or a successor-subscriber arrangement addresses the RESP, so your child's education savings — and any government grants — aren't lost or collapsed. The rules for successor subscribers are specific; ask your advisor and lawyer to coordinate this.


5. Powers of attorney — for you, not just your kids

Estate planning isn't only about death. The likelier scenario for a young parent is a temporary incapacity — a serious accident or illness — where you're alive but unable to make decisions. A will does nothing in that situation.

You need two powers of attorney, each a document naming someone to act for you if you can't:

For two-parent households, spouses usually name each other first, with an alternate for the case where both are affected (the same accident, for instance). For single parents, choosing the right people here is just as important as choosing a guardian.

💡 Without these documents, your family may have to apply to court or to the government to be appointed before they can manage your affairs — exactly when they're least able to deal with paperwork.


What happens if both parents die without a will?

If you die intestate (without a valid will), Ontario's Succession Law Reform Act decides everything — and the defaults are blunt:

In short, the province writes a one-size-fits-all plan for your family, and it's almost never the plan you'd have written yourself. For parents, the cost of doing nothing is paid by your kids.

Mini-FAQ

Q: Do we each need our own will, or can we share one? Each parent should have their own will. "Mirror wills" — two separate but matching wills — are common for couples and let each of you address your own assets and wishes.

Q: At what age will our kids get the money? Whatever age you choose in the trust. The only default is the one you're trying to avoid: 18, the age at which an unplanned inheritance is released outright.

Q: Can the guardian and the trustee be the same person? Yes, but they don't have to be — and often shouldn't be. Splitting "who raises the kids" from "who manages the money" adds accountability and lets you pick the best person for each job.

Q: We don't have much. Do we still need this? Yes. Guardianship and powers of attorney have nothing to do with wealth, and even a modest estate plus a life insurance policy can leave enough that you'd want it managed — not handed to a teenager.
