If nothing else works, call 9-1-1 and explain what you're going through, or what whoever you're worried about is going through. Someone there will help you.
For 9-1-1 callers in Toronto, there is a "Warm Transfer Line".
The Distress Centre has a partnership with Toronto EMS in the provision of a dedicated line for at risk callers. When callers have provided their location, the dispatcher transfers the call to the Distress Centre for support until paramedics arrive ( if required ).
Also, on subway platforms, callers can push the blue
button on the payphones. They are then assessed for their level of risk, and a decision is made as to whether Transit Control should cut the power to the third rail.
There are also hotlines on the Bloor Viaduct.
