No. As a matter of fact, I was there with the family on Thursday to warm and charge up and worked from the office yesterday too.
I didn't; my UPS lasted two hours ;-) but Cable internet was down anyways. Mobile internet and cell phone service. was affected for four days in the West Island.
WHC's servers were not affected; they also have backup power and generators if it's needed.
Gas pumps need electricity. Many of them were out of service during this "event" here, too.
While I didn't live in Canada, I also managed to be visiting for the big Ice Storm in 1998, but I can't recall how long we were out of power then, it was more of an adventure. We tried to go skiing in the US at that time but turned around halfway.
