The City of Clarence-Rockland has declared an official state of emergency due to flooding on the Ottawa River.

Mayor Guy Desjardins made the declaration on Friday morning based on the weather forecast from Environment Canada and predictions that water levels on the river would exceed those of the 2017 flood.

Environment Canada issued a Special Weather Statement explaining 20 millimetres (0.9 inches) to 25 millimetres (1.4) inches of rain is possible by Saturday.

In the declaration, Desjardins stated he believes the forecast creates a situation, or “impending situation” that could cause a danger of “major proportions” resulting in harm to people or property in the city.

The Clarence-Rockland declaration follows one made in the City of Ottawa on Thursday.

Three other towns in central Ontario have also declared states of emergency due to flooding.

Emergency Management Ontario (EMO), the division of the Ministry of the Solicitor General which coordinates emergency measures, will assist municipalities that have declared states of emergency.
