==Pluvial (Surface) flooding==  

Pluvial flooding occurs when a heavier storm exceeds the urban drainage capacity and causes flooding in some low-lying areas. This results in traffic interruption, economic loss, and other issues. As the climate changes, the incidence of extreme weather events in Ontario is expected to increase and the urban drainage capacity may be overwhelmed more often.
