No, it wasn’t helicopters from the G20, it was a genuine–and rare–earthquake.
By City of Toronto –
In our initial assessment, there has been no major damage to City infrastructure. Further investigations are taking place to confirm. The Toronto Transit Commission and Transportation Services have reported that there has been no damage to their infrastructure or interruptions to service.
The City’s Emergency Operations Centre is up and running in preparation for the G20 so the City is uniquely prepared to respond to the event. We will continue to monitor the situation and will report as necessary.
Residents should follow the instructions of their building management.
The City has received no calls concerning bridge, building or other infrastructure problems.
While not applicable to this event, in future, should there be a major or more serious earthquake:
Residents should stay away from glass, windows, outside doors and walls. DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON until the shaking stops.
If there isn’t a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building.
If outdoors – stay there. Move away from buildings, streetlights, and utility wires. Once in the open, stay there until the shaking stops.
If in a moving vehicle, stop as quickly as safety permits and stay in the vehicle. Avoid stopping near or under buildings, trees, overpasses and utility wires.
