TORONTO, April 30, 2026 (GLOBE NEWSWIRE) — Today, the investigative journalism bureau broke a story that exposes the unimaginable cruelty that has been taken place at a research facility within York University. Video footage recorded inside a York University research facility by a whistleblower working with a U.S.-based group Last Chance for Animals (LCA) reveals disturbing conditions and ethically questionable research practices. The research involves at least nine non-human primates, six of whom have been confined at the facility in Ontario for up to 17 years. Animal Alliance of Canada is calling on the Premier to immediately ban all primate research in the province.

Prolonged invasive experimentation, repeated surgical interventions, sensory impairment, chronic confinement, and water deprivation raise serious ethical and governance questions.

Where equivalent or superior data can be obtained using human-relevant, non-animal models, continued animal use becomes scientifically redundant and morally indefensible.

A Pattern of Mistreatment in Ontario’s Primate Laboratories

Article content

York University’s violations are not an anomaly. Freedom of information records obtained by Animal Alliance of Canada from the Ontario Ministry of Agriculture (then the Ministry of Agriculture, Food and Rural Affairs) reveal that other serious welfare failures involving monkeys have been documented in Ontario laboratories. These inspection reports expose longstanding, systemic problems in Ontario’s primate laboratories, including failures in care, accountability, and the most basic safeguards for animal welfare.

In one 2017 inspection, a macaque who had tested positive for Methicillin-resistant Staphylococcus aureus (MRSA) was kept in prolonged solitary confinement despite clear signs of distress. Inspectors reported he appeared “depressed and restless,” had lost interest in food, and was exhibiting self‑injurious behaviour, including hair‑pulling and significant hair loss. Records also showed he was not provided with any exercise opportunities.

Inspectors also suggested the lab “give serious consideration to the implications of maintaining” another monkey who had a chronically infected cranial implant and posed an infection risk to other monkeys.

A separate inspection that same year documented the deaths of four monkeys from brain infections and abscesses within a six‑week period. One monkey scheduled for an MRI was instead euthanized without the clinical veterinarians being informed — a direct breach of university policy and basic veterinary oversight. Inspectors warned that communication failures between research staff and veterinarians were contributing to serious lapses in health management.
