A new federal flood mapping tool is being positioned as a catalyst for national collaboration, with municipal leaders stressing that its success will depend on strong, transparent data and coordination across all levels of government.
“Municipalities are the first to respond and the first to see the growing impacts of climate change every day, and we welcome the federal government’s update on Canada’s Flood Risk Finder to strengthen flood awareness and preparedness,” said Rebecca Bligh, president of the Federation of Canadian Municipalities. “Reducing exposure to flooding will take sustained collaboration across all orders of government.”
The comments came as Public Safety Canada announced that technical development of Canada’s Flood Risk Finder — the country’s first national, publicly accessible flood hazard and risk platform — is now complete.
Bligh said the online tool will build on the resilience measures municipalities already have underway. The Flood Risk Finder is designed to give Canadians a clearer, more consistent picture of flood risks across the country. Using a simple address search, users will be able to view their local flood risk on a four-point scale ranging from low to extreme, alongside information on the types of flooding that may occur, including coastal, riverine and rainfall-related events.

Funding provided by the Flood Hazard Identification and Mapping program enabled the procurement and development of Federally Identified Flood Risk Areas datasets, which provide the underlying data for Canada’s Flood Risk Finder.
Federal officials say the new platform is intended to close long-standing gaps in access to flood risk data, which has often varied widely between jurisdictions and has not always been easy for the public to interpret.
However, the availability of local data will depend on whether provinces and territories choose to participate. While the federal government has built the platform, jurisdictional responsibility for flood management means regional governments must opt in for their data to be included and made searchable.
Public Safety Canada said it will work with provinces and territories over the coming months to support participation, with public rollout to occur as jurisdictions join the platform.
The initiative brings together expertise from multiple federal departments, including Natural Resources Canada, Statistics Canada and Public Safety Canada, combining data development, mapping and usability testing to create what officials describe as a user-friendly and authoritative source of information.
Beyond improving public awareness, the tool is also expected to support emergency management planning and encourage property owners to take preventative action.
“Clear, accessible information empowers homeowners and renters to make more informed decisions and take practical steps to mitigate their risk,” said Liam McGuinty, vice-president of federal affairs at the Insurance Bureau of Canada, in a statement.
Flooding remains Canada’s most common and costly natural disaster, with average annual damages exceeding $2 billion. As climate change intensifies the frequency and severity of extreme weather events, federal officials say improving access to risk information is a key component of broader efforts to strengthen national resilience.
The federal government is encouraging Canadians to use the new platform alongside existing provincial and local resources, emphasizing that proactive risk reduction is significantly more cost-effective than post-disaster recovery.
Minister of Emergency Management and Community Resilience, Eleanor Olszewski, said the Flood Risk Finder is intended to support conversations between governments, communities and individuals on how to better prepare for future flood events, framing the tool as part of a wider shift toward more coordinated and preventative climate adaptation strategies.
