Montreal-area paramedics have a new dispatch system. They fear it's putting patients at risk

CBC News spoke with five paramedics who say they’ve been sent out to respond to 911 calls unnecessarily — either because the call had already been handled by another team and reappeared in the system, or because several ambulances were dispatched to the same call. Urgences-santé, meanwhile, insists there’s been no impact on patient care since the system was implemented.
