Why Flash Floods Are Getting Worse in Canada

Written By Madison Henry

Flash floods are now one of the fastest-growing climate threats in Canada. Here's why.

What’s Behind the Rise:

  • Heavier rainfall due to climate change

  • Urbanization = more pavement, less absorption

  • Outdated infrastructure in cities can’t keep up

Recent Canadian Flash Floods:

  • Toronto, 2018 – 60mm of rain in 90 minutes

  • Calgary, 2013 – $5B in damages from storm-driven flooding

  • BC, 2021 – Roads, farms, and homes devastated by record rain

How You Can Prepare:

  • Install sump pumps, seal basement cracks

  • Know your insurance coverage (flood isn’t always included!)

  • Get to know your neighbours—community response matters

Flash floods don’t give you time to think. Planning ahead saves lives.
