Renfrew County’s Chief Paramedic is sounding the alarm over ambulance response times, as a system serving the largest geographic county in Ontario continues to feel a healthcare pressure point. Mike Nolan presented a very grim picture of the situation during a Health Committee meeting last week. He says the availability of ambulances has been significantly reduced over the past two years, especially at night when the available number is running on empty. He joins Kristy Cameron on Ottawa Now.
