British Columbia continues to report the highest number of cannabis poisonings among pets in Canada, according to new data from Trupanion (NASDAQ: TRUP).
Veterinarians and insurers are urging pet owners to use cannabis cautiously at home. Additionally, seasonal spikes in incidents have drawn renewed attention to the issue.
Over the past six years, Trupanion has recorded more than 1,800 cannabis-related toxicity claims nationwide. In 2025, British Columbia led with 103 reported cases. Meanwhile, Alberta followed with 52, and Nova Scotia reported 35 incidents.
Nick VinZant, director of public relations for Trupanion, said the number of cases in British Columbia has risen steadily since 2020. In addition, most incidents involve dogs exposed inside the home environment. Cats account for a smaller share of reported cases.
“I know this may look like the numbers of incidents are increasing and decreasing, but we also have to factor in the number of pets currently enrolled,” said VinZant.
“If we do that, the number of incidents increased by 7.6 per cent in British Columbia since 2020 and decreased by 5 per cent in Canada over the same time period.”
In 2020, the province recorded 59 affected animals. However, that number climbed to 103 by 2025, reflecting a notable increase. Nationally, figures have fluctuated, though overall trends show some decline outside British Columbia.
Veterinary treatment costs can vary widely depending on severity. Additionally, Trupanion data places typical bills between CAD$400 and CAD$1,100, with some cases reaching CAD$800 or more.

Early intervention can reduce complications
Animals may show drooling, vomiting, or unusual changes in breathing and body temperature. Symptoms can appear within minutes or take up to 12 hours after exposure.
If exposure is suspected, veterinarians recommend immediate contact with a clinic or Animal Poison Control. Consequently, early intervention can reduce complications and shorten recovery time.
Marijuana toxicity in pets most often occurs when animals ingest cannabis products. Edibles like gummies, chocolates or baked goods pose a major risk because they contain concentrated THC. Additionally, these products often include other harmful ingredients such as chocolate or xylitol.
Pets can also inhale secondhand cannabis smoke. However, ingestion remains the leading cause of toxicity due to higher THC absorption. Dogs, in particular, tend to consume accessible items, increasing their risk in household settings.
