British Columbia is the outlier every Canadian owner should understand. Since January 2024 the Family Law Act treats pets as companion animals, and courts weigh who acquired and cared for the animal rather than who simply paid. A BC court still cannot order joint possession, but it will enforce a private agreement that does, which makes a written pet care or shared-possession contract more powerful in BC than anywhere else in the country. For couples in the province, this document is often the only path to the shared arrangement a judge is barred from imposing.
Ontario remains firmly in the property camp. In Carvalho v. Verma (2024 ONSC 1183) the Superior Court restated that a dog is personal property much like other chattels, and that ownership, not affection or best interests, decides who keeps it. For boarding and sitting, the Ferguson v. Birchmount standard governs, so a paid Ontario caregiver carries the burden of proving they were not negligent. A clear written standard of care is the caregiver's best protection in this province.
Alberta follows Ontario's property approach and has expressly declined to import a best-interests test for animals, as the Court of King's Bench confirmed in 2024 when it split four cats between former partners on ownership grounds. Written proof of who acquired and cared for the animal carries real weight here, so the identification and care-history terms matter.
The Atlantic and Prairie provinces have not legislated a companion-animal regime and continue to apply ordinary property and bailment principles, with provincial animal-welfare statutes setting the humane-treatment floor. Wherever you are, if the caregiver arrangement is really a business relationship, our independent contractor agreement drafted for CRA rules may be the better instrument for a professional sitter.
