Criticism and controversies Humber River Health lawsuit In June 2025, a consortium led by Plenary became the subject of a $100 million lawsuit filed by the Humber River Hospital, alleging negligent design and construction practices. The hospital alleged that a "sizeable portion" of the facility's floors are not level or flat, are deteriorating and such conditions have required the hospital to take extra precautions for patients and equipment safety as a result. Plenary Health Care Partnerships was contracted by the Government of Ontario to operate and maintain the hospital for a 30 year period.
