On Saturday, October 11, 2014 Calgary suffered a blackout as a result of an underground electrical fire located on 8 Street SW between 5th Avenue and 6th Avenue. The following is a rough timeline of the events as we saw them, living directly beside it.

8:17 pm: Honking heard from outside. Found streetlights on 8 street SW were malfunctioning from 4 Avenue to 10th Avenue. Some lights all green, others all red, some flashing, one completely dark. We called the non-emergency Calgary Police line to report it. Police and transit on scene immediately to direct traffic.

Here is a compilation of all the videos that we recorded with our camcorder during the emergency. Not all clips are in the right order but we had to work fast with a generator to get this post accomplished. – Mrs & Mr. Crackmacs <3

Calgary Blackout: Evacuation

This notice came over our in-suite intercom multiple times, warning us to evacuate or be prepared to evacuate if it becomes mandatory.

Calgary Blackout Conclusion

Investigators believe the origin of the fire was a relay used to control street lights. Due to the extent of the damage caused by the fire and a subsequent blaze a few hours later, investigators cannot determine what caused the relay failure.
