In 2013, relentless torrential rains in Alberta, Canada, unleash one of the most catastrophic natural disasters in the province's history — a deluge that would come to be known as the “Flood of Floods.” Rivers overflow, entire neighborhoods are submerged, and over 100,000 people are forced to flee their homes as the sheer speed and force of the rising waters take communities completely by surprise. It is a disaster that tests emergency response systems and leaves behind billions in damages.
