These programs monitor a broad array of different public health indicators, many of which can be used to track the effects of climate change-induced hazards afflicting Ontario. The Acute Care Enhanced Surveillance Program (ACES) is designed so that it can both monitor broad-spectrum, diffuse health effects like the spread of a disease such as influenza through a community and also narrow its search down to isolate the effects of an acute incident such as the health problems that occur on account of air quality problems due to a forest fire. The Public Health Information Management System (PHIMS) has the ability to monitor potential health effects of air quality events, extreme heat and extreme cold events, storms, forest fires, and more. Many of these listed hazards are expected to increase in severity and frequency over time as a result of the changing climate. By having robust and responsive monitoring and alert systems such as ACES and PHIMES, Ontario is much more well-prepared to handle the perils posed by these hazards than it previously was.
Originally developed in the wake of the SARS outbreak, the Acute Care Enhanced Surveillance (developed in 2004) and the Public Health Information Management Systems (developed in 2015) have provided Kingston, Frontenac, Lennox, and Addington Public Health with an effective means of tracking public health data and responding to extreme events. This system tracks in real-time public health indicators that can provide information on a variety of subjects such as communicable diseases, overdose deaths as a result of novel illicit drugs, and also the effects of climate related hazards such as heat waves and breathing problems associated with smoke from wildfires. Originally just a pilot program in the Kingston, Frontenac, Lennox, and Addington Public Health jurisdiction, this program has proven itself successful and has now been implemented all across Ontario.
