Extreme precipitation events are intensifying across Canada, increasing the frequency and severity of urban pluvial flooding. Current flood risk assessments often rely on fragmented, localized models that fail to capture the complexity of urban drainage systems and surface runoff interactions. This gap limits our ability to accurately estimate flood depths, extents, and associated risks under changing climate conditions. This presentation will outline the case for a Canada-wide, integrated pluvial flood modeling framework; one model capable of consistently estimating urban flood hazard and risk across diverse geographies. We will explore how such a model can incorporate both explicit and implicit representations of urban drainage systems, including catch basins and stormwater infrastructure, to better reflect real-world conditions. The session will highlight key challenges, data requirements, and methodological considerations for building a scalable, national platform that supports climate-informed risk assessments and resilient urban planning. By the end of this session, participants will understand why a unified approach is critical and how collaborative research and action can close existing gaps. We encourage researchers, practitioners, and policymakers to contribute to the development of this next‑generation modeling effort, recognizing that improving our understanding of future flood risks depends on building effective tools today.
