issued to:     school boards, municipalities, local conservation authorities, local police, emergency services and media


Weather Conditions:

Toronto and Region Conservation advises that over 30mm of rainfall has fallen on parts of the GTA, with more heavy rainfall expected through the afternoon and evening. Toronto and Region Conservation authority advises that flooding is likely.



All rivers within the Greater Toronto area will be experiencing high flows and water levels, resulting in unsafe conditions. The Don River has yet to peak and is still rising.  Therefore, there is a potential for flooding of the Bayview Avenue extension. We are closely monitoring other transportation routes and sites adjacent to the Don River.



Please exercise extreme caution around all bodies of water and avoid driving in low-lying areas and roadways particularly at underpasses.  Please alert any children under your care of these dangerous conditions and supervise their activities. Be alert for possible transportation delays and road closures.


Toronto and Region Conservation will continue to monitor the weather and watershed conditions and will issue further messages as necessary. This Flood Watch will be in effect through Thursday October 29, 2015.  For more information please contact the on-call Flood Duty Officer.
