A massive thunderstorm hit Edmonton on Saturday evening, surprising residents across the region.
Rain was so heavy it brought down power lines and snapped trees.
Several parts of the city went dark as the storm raged through.
Water from the rain filled buildings like the West Edmonton Mall and the Royal Alberta Museum in minutes and spilled onto surrounding streets.
Big roads turned into rivers, flooding 111 Avenue and Jasper Avenue, and compelling traffic to halt.
Two outdoor festivals got cancelled because of the flooding as water rose and left organisers to pack up equipment.
Clean-up teams are working now to restore safety while residents await power to return.
City bosses called it the worst storm this season so far in recent memory, promising decisive action to repair damage.
