Collingwood, ON [15 December 2025] – The amended Boil Water Advisory (BWA) issued on December 13 2025 has been lifted as of noon by the Simcoe Muskoka District Health Unit for the impacted areas mainly in the eastern and southern parts of the Town of Collingwood (shown in the linked map), including Hwy 26 East and surrounding areas east of the Pretty River and properties between Poplar Side Road and Tracey Lane/Findlay Drive. Laboratory test results have confirmed that the water is free from contamination and is safe to drink. Any facilities that were closed due to the advisory can now reopen after taking the necessary precautions.
Residents and businesses in the eastern and southern parts of Collingwood as shown on the map and list of affected streets should take the following steps before using their water:
- Run all cold faucets for a minimum of five minutes. If the water does not run clear after five minutes, contact the Town of Collingwood at 705-445-1030.
- Run drinking water fountains for a minimum of five minutes.
- Run all water softeners through a regeneration cycle.
- Replace pre-filters and follow the manufacturer’s instructions for reverse osmosis units.
- Replace water filters, as they are disposable and may be contaminated. This applies especially to carbon filters and others that are near the end of their life.
- Drain and refill hot water heaters set below 45°C (113°F). Normal setting is 60°C (140°F).
- Drain and flush all ice-making machines and soda fountain machines.
- Flush, clean and sanitize appliances with water line connections (e.g., fridges with water and ice dispensers), following the manufacturer’s instructions.
- Dispose of any ice made since Friday, Dec. 12, 2025.
- Large-volume users (for example, restaurants) may need to run cold water taps for a longer period of time on first use to ensure the water is not cloudy.
Note: Please consult the manufacturer or owner’s manual for detailed instructions on how to flush and disinfect ice or soda fountain machines and how to restart water treatment devices.
