Naming a guardian for your children

Your will is where you name who raises your children if both parents die. How the appointment works in each province, how to choose, and the money side of raising someone else's kids.

This is the clause that gets parents to finally write a will, and rightly so: if both parents die without one, the people who love your children apply to a court that has never met you, possibly against each other.

How the appointment works

In all three provinces, a will can appoint a guardian, and in all three the appointment is the strongest signal you can leave — but not an unreviewable command. The mechanics differ:

  • Ontario: an appointment under the Children’s Law Reform Act is temporary — effective for 90 days, during which the guardian applies to court for permanent custody. The court decides on the child’s best interests, and the will’s nomination carries heavy weight in practice.
  • British Columbia: a guardian appointed by will becomes the child’s guardian on your death under the Family Law Act. BC also lets you appoint a standby guardian who can act while you are still alive but no longer able — unique among our three provinces and valuable for parents with serious illness.
  • Alberta: the Family Law Act allows appointment by will; the appointment takes effect on death, subject to the court’s ability to review.

In every province, a surviving parent with custody rights generally continues as guardian — your appointment matters for the case where both parents are gone.

Choosing: the questions that actually decide it

Values first — the guardian is raising them, not hosting them. Then capacity honestly assessed: your parents may be wonderful and also seventy-one with a toddler on the way to sixteen. Then the disruption question — the guardian who lets the kids keep their school, friends and city has a real advantage. Then their household’s consent: their spouse is signing up too.

Name a backup guardian. And ask the people first — this is not an appointment to spring on someone at a funeral.

The money is a separate decision

The guardian raises the children; the trustee controls the inheritance (how trusts for minors work). Same person is simplest; different people creates a healthy check on large funds. Either way, make sure the trust wording lets the trustee actually fund the guardian’s real costs — a bigger car, a finished basement, camp fees — without guilt or applications. Ours does.

Pets, while we are here

A pet is property, so it passes like property — but you can name a pet guardian and leave them a cash gift toward the animal’s care. Both are in our questionnaire. The money goes to the person, not the pet; Canada does not do Leona Helmsley trusts well, and a modest gift to a chosen person works better than legal engineering.
