This story is part of 20 Years in Isolation, the Star’s ongoing investigation into the use of psychiatric seclusion at Waypoint Centre for Mental Health Care. The Star’s initial four-part series on the hospital’s practices has been met with calls for an independent review of Ontario’s mental health system.

The Ontario government has been aware for at least eight years of serious concerns about a psychiatric hospital’s practice of keeping patients in isolation for prolonged periods of time, the Star has learned — a practice that was recently found to be akin to torture.
