The request comes as the result of a resolution, passed by city council, to ask for an investigation into the floods.

The city has asked the provincial and federal governments to open a formal investigation into the Ottawa River floods.

Mayor Jim Watson wrote letters to both Prime Minister Trudeau and Premier Ford, requesting that their governments open a formal investigation into both this spring's floods on the Ottawa River, as well as the floods of 2017.

"Many residents in the affected areas of Ottawa will be waiting for reliable information on the factors contributing to these flooding events, and the likelihood of reoccurrence, before making a decision on rebuilding their homes," Watson wrote.

The request comes as the result of a resolution, passed by city council, to ask for an investigation.

Speculation about the flooding has led to conspiracy theories being peddled on social media and through anonymous letters, about the cause of the floods and why the floodwaters submerged the areas they did.
