Road Flooding Frequently Asked Questions

  • Why does the roadway flood in heavy rainfall events?

    During periods of heavy rainfall, the roadway drainage and storm sewer systems may not have sufficient capacity to drain the water as quickly as during normal rainfall. Please allow the system adequate time to clear. However, if you are aware of a blocked catch basin or culvert, please call the Municipal Service Centre at 905-356-1355 ext. 6200 to request a cleanout.Categories: Drainage, Municipal Works, Road Flooding
