What happened

A transformer explosion triggered a power surge in the Georgetown area, sparking fires and knocking out power to some homes. Fire services received 28 calls for service ranging from reports of fire to odour investigations and smells of smoke. Two calls related to fires at homes on Ballantine Drive and Lookout Court, both of which were extinguished. Electricity was later restored, though residents experiencing outages were advised not to reset breakers until an electrician could inspect their electrical panels. A nearby shopping mall was evacuated as a precaution due to reports of smoke, with normal operations resuming afterwards. No injuries were reported.

Lessons learned

  1. Following a power surge or transformer event, residents should not reset circuit breakers until electrical panels have been inspected by qualified personnel.
  2. Emergency services should methodically respond to all reports of smoke or odour after grid incidents to confirm no ongoing hazards.
  3. Precautionary evacuation of nearby public buildings may be warranted until the extent of smoke or fire spread is confirmed.
