There's a reason why I bring this up. You're probably too young to remember this, but in 2003, the northeast blackout saw 50 million people lose electricity across Ontario and seven American states. On July 8, 2013, 300,000 Torontonians saw a power outage, and 1,400 passengers were trapped in trains and subways, and whatnot. It took them hours to free these individuals.
When there's a power outage of that magnitude, nothing works. I lived through the 2003 outage. At the time I was working at a financial institution, and we had to shut everything down, obviously, for reasons I'm sure you're aware of.
How can we communicate when things like this happen?
