From the Toronto and Region Conservation Authority:
Due to the weather system bringing approximately 50 mm of rain to the Greater Toronto Area, streams and rivers will have higher than normal water levels and flows. Rapidly rising or fast moving water can create dangerous conditions. The possibility exists for flooding on roadways and in low-lying areas.
Please exercise caution around all bodies of water and stay away from rivers and streams. Please alert any children under your care of these dangers and supervise their activities. Please avoid driving through flooded roadways.
This Flood Outlook Statement will be in effect through Saturday, April 8, 2017. TRCA will continue to monitor the weather and watershed conditions. For more information please contact the on-call Flood Duty Officer.
