British Columbia reported the highest number of marijuana toxicity claims for pets in Canada over the past five years, according to pet insurance provider Trupanion. From 2020 to 2024, B.C. accounted for nearly 40 per cent of Canada’s 1,831 cannabis poisoning claims, with 638 cases filed—far ahead of Ontario (458 claims) and Alberta (344 claims).

In 2024 alone, B.C. led the country with 129 marijuana-related vet claims, followed by Ontario with 117 and Alberta with 66. Trupanion notes that while marijuana is legal in Canada, cannabis products must be specifically formulated for pets and prescribed by a veterinarian to be safe for animal use.

Vet bills for marijuana toxicity averaged between $400 and $1,100 nationwide, with Newfoundland and Labrador posting the highest average at $661 per claim. B.C. claims averaged $554.

Dogs and cats are particularly sensitive to cannabis, given their higher number of cannabinoid receptors. Symptoms of marijuana poisoning can appear within 30 minutes to a few hours and include lethargy, vomiting, dilated pupils, breathing issues, and urinary incontinence.

Trupanion urges pet owners to seek immediate veterinary care if exposure is suspected, as treatment can vary depending on the form and method of marijuana ingestion.
