There was some talk of blaming southern Ontario for the blackouts, because of this region's heavy use of power and it might be pretty justified.
The Premier, Ernie Eves was telling people to close their busineses for the day unless they were necessary for people to get to as well as shut off their air conditioning but alas, I was at work along with quite a few others in various, day to day and relatively unnecessary stores and cities like Peterborough lost their power a short while after it got back on by using too many appliances right away and overloading again.
Luckily there was not a huge amount of looting or rioting, although a bit did happen in Toronto that I know of. Mostly everyone was just partying everywhere and having giant barbeques to get rid of food before it could go bad.
