In Ontario, pets are legally treated as property in a divorce or separation, not under any "best interests of the pet" test used for children. Courts decide pet ownership disputes by looking at factors like who purchased or adopted the animal, whose name is on adoption or purchase records, who has paid for its care, and who has been the primary caregiver day to day. Ontario has not adopted British Columbia's 2024 approach of treating "companion animals" as a distinct category with ownership-sharing options — as of now, it remains a straightforward property question here.
- Ontario treats a pet as property, the same as a car or furniture — there is no "best interests of the pet" legal test like there is for children.
- Courts look at who paid for the pet, whose name is on adoption or purchase records, and who has provided day-to-day care.
- A clear pre-acquisition agreement (even an informal written one) about who owns the pet carries significant weight if a dispute arises later.
- British Columbia amended its Family Law Act in 2024 to treat "companion animals" differently and allow shared-ownership arrangements — Ontario has not followed that approach.
- Because courts cannot order shared "access" to a pet, resolving pet ownership by negotiation or mediation is almost always more practical than litigating it.
- Veterinary and licensing records, along with who historically paid pet-related expenses, are the most persuasive evidence in a dispute.
Pets Are Property, Not Children
This surprises a lot of separating couples: Ontario law does not have a "best interests of the pet" framework the way it has a best-interests-of-the-child test for parenting disputes. A pet, however loved, is legally categorized as property — the same broad category as a car, furniture, or a joint bank account. That means a court asked to resolve a pet dispute is not deciding what is best for the animal; it is deciding who owns it, full stop.
Because a pet is property, Ontario courts generally cannot order a shared-custody-style schedule — alternating weeks, for example — the way they can for children. A court resolving a contested pet-ownership claim will award the animal to one party as owner, not divide time between two owners.
How Ownership Is Actually Decided
When a pet-ownership dispute does need to be resolved, courts and negotiators generally look at practical, document-based factors:
- Who purchased or adopted the animal, and whose funds were used
- Whose name appears on adoption papers, purchase receipts, microchip registration, or municipal licensing
- Who has paid for food, veterinary care, grooming, and other ongoing expenses
- Who has provided day-to-day care — walks, feeding, vet appointments — particularly in the period closest to separation
- Whether there was any prior written or verbal understanding between the spouses about ownership
None of these factors is a formal legal test the way the factors in a common-law property dispute might be — they are simply the practical evidence that tends to persuade a court, or a mediator, that one party has the stronger ownership claim.
How This Differs From British Columbia
British Columbia amended its Family Law Act, effective January 2024, to specifically define a "companion animal" as its own category of property and give courts explicit authority to weigh ownership-style factors — and, in some circumstances, even structure a form of shared arrangement. That change followed years of BC case law wrestling with how to treat pets fairly on separation.
Ontario has not made an equivalent legislative change. As things currently stand, pets here remain ordinary property, decided under the same general framework as other disputed belongings described in our guide to how property is divided in an Ontario divorce. Anyone who has seen BC media coverage of pet-sharing orders should not assume the same options exist here — they do not, at least not currently.
What Evidence Actually Matters
If a pet dispute is heading toward negotiation or, in rare cases, court, gather: veterinary records showing who is listed as the primary contact and who historically attended appointments; purchase or adoption paperwork; municipal licence registration; bank or credit card records showing who paid for food, supplies, and vet bills; and any texts or emails discussing the pet's care or ownership. The party who looks, on paper, like the pet's primary owner and caregiver has the stronger claim.
A couple adopts a dog together before marriage, with the adoption paperwork in one spouse's name only, though both contributed financially at the time. After separation, the other spouse pays most vet bills and is the dog's primary daily caregiver for the next year. In a dispute, a court or mediator would weigh both the paperwork and the more recent caregiving pattern — illustrating why ownership questions are rarely as simple as "whoever signed the form."
Avoiding a Pet Dispute Before It Starts
The cheapest way to resolve a pet dispute is to never have one: couples who are cohabiting or marrying with a pet already in the picture can address ownership explicitly in a cohabitation agreement or prenuptial agreement, the same way they might address other property. It feels unnecessary in the moment — most couples do not think to do this — but a one-paragraph clause avoids a genuinely painful dispute later.
Why Negotiation Beats Litigation Here
Because courts cannot order a shared-time arrangement, litigating a pet dispute produces an all-or-nothing outcome: one party keeps the pet, and the other typically gets nothing in return except whatever offsetting value the pet represents in the overall property division. Most separating couples are better served by negotiating directly or through mediation, where an informal shared arrangement — alternating visits, for example — can actually be built into a workable agreement, even though no court would impose the same thing. A separation agreement can record that arrangement in writing, giving it practical, if not strictly court-enforceable, weight between the parties.

Frequently Asked Questions
No. Ontario courts do not have jurisdiction to order custody, access, or visitation schedules for a pet the way they can for a child. A pet is legal property, and a court asked to resolve a pet dispute will decide only who owns the animal, not a shared-time arrangement.
By applying ordinary property-ownership principles: who purchased or adopted the animal, whose name appears on adoption papers, purchase receipts, or licensing and veterinary records, and who has historically paid for and provided its day-to-day care. There is no presumption in either spouse's favour based on who "loves the pet more."
Not as a formal legal factor. Ontario's approach is ownership-based, not welfare-based, so a court will not weigh emotional bond the way it weighs a child's best interests. In practice, though, parties who negotiate directly often do consider bond and daily routine informally in reaching their own agreement, even if a court wouldn't be required to.
No. British Columbia amended its Family Law Act effective January 2024 to define "companion animal" separately from other property and allow courts to weigh ownership factors and even order shared arrangements in some cases. Ontario has not made an equivalent legislative change, and pets here continue to be treated as ordinary property.
Yes, and this is usually the most practical path. Nothing prevents separating spouses from negotiating their own agreement about pet ownership or even an informal shared-time arrangement — a court simply won't impose or enforce a shared-time schedule the way it would for children if the agreement later breaks down.
Pre-marriage joint purchases are treated like any other jointly acquired asset: ownership generally follows the purchase and registration records from that time, unless a separation agreement or other evidence establishes a different understanding between the parties.
