For many pet owners, figuring out what happens to a beloved animal after death matters just as much as anything else in the will. Ontario law gives you two broad ways to plan for it: naming a pet guardian, or setting up a formal pet trust. They solve the same underlying problem in very different ways.

Neither approach is automatically better. The right one depends on how much money you want to set aside, how much you trust the people involved, and how complex your pet's needs are. Here's how each actually works.

Why You Can't Simply "Leave Money to Your Pet"

Under Ontario law, a pet is legally treated as property, not as a person capable of inheriting. That means a will provision that tries to leave money directly "to" a pet has no legal beneficiary to receive it — a gift needs to go to a person, or be held on specific, properly drafted trust terms. This is the starting point for both options below: you're always really making arrangements for a person, or a trust, to look after the animal, not gifting anything to the pet itself.

Option 1: Naming a Pet Guardian

The simpler and far more common approach is naming a specific person as your pet's guardian in your will, and leaving that person a sum of money, typically as an outright gift, sometimes accompanied by a non-binding letter of wishes describing your pet's needs and routine.

This works well when:

Option 2: Setting Up a Pet Trust

A more formal option holds money in trust, with a trustee responsible for administering funds specifically for your pet's care over its lifetime, rather than handing a lump sum to the caregiver outright. This adds a layer of oversight the simple guardian approach doesn't have.

Purpose trusts for the care of a specific animal are a recognized, if less commonly used, estate planning tool, but they need careful drafting, including a defined duration, a mechanism for what happens to any funds left over after the pet dies, and clarity about who can enforce the trust's terms. This is a more technical document than a simple gift and benefits from being drafted by a lawyer experienced in this area.

Which Approach Fits Your Situation

Consider a pet trust rather than a simple guardian gift if:

If none of these apply strongly, a straightforward pet guardian clause with a clear letter of wishes is often all a family actually needs.

Frequently asked questions

Can I name more than one backup pet guardian?

Yes, and it's a good idea. Naming at least one backup accounts for situations where your first choice is unable or unwilling to take the pet when the time comes.

Does a pet trust need to end at some point?

Generally, yes. A trust set up for an animal's care is typically structured to run for the animal's lifetime rather than indefinitely, with the will specifying what happens to it afterward.

Is a verbal promise from a friend to take my pet enough?

No. A verbal understanding isn't legally binding and isn't something an estate trustee can act on with confidence. Putting the arrangement in your will, with any funds clearly addressed, is the only way to make it enforceable and clear.

What if I can't decide between the two options?

Many people start with a straightforward guardian clause and revisit whether a formal trust makes sense as their pet's needs, their assets, or their family situation change. Your will can be updated as circumstances evolve.
