Ontario training-facility Quarter Horse tests positive for strangles

A Quarter Horse in Ontario has tested positive for strangles at a training facility in Wellington, according to an EDCC Health Watch report published by The Horse. The case adds to a steady run of strangles activity in the province, where Ontario’s surveillance system has tracked multiple affected facilities in 2025. In Ontario, positive Streptococcus equi test results are immediately notifiable to the province, and the standard response is voluntary movement restriction and biosecurity oversight at the farm or facility level.

Why it matters: For veterinary professionals, this is another reminder that training, boarding, and mixed-use horse facilities remain high-risk settings for strangles introduction and spread, especially when horses move on and off property or commingle with animals of unknown health status. Ontario guidance specifically recommends quarantining new arrivals and horses returning from events or training for more than two weeks, and the province’s recent surveillance reports show strangles remained active across multiple facilities through 2025.

What to watch: Watch for any follow-up alerts on additional exposed horses, expanded voluntary quarantine measures, or links to recent horse movement into or out of the Wellington facility. (oahn.ca)
