I turned off the water at the main and then opened all my faucets and left them open. Luckily my pipes didn't freeze and the house was under 0'C (32'F) for about 5 days straight. I brought my Bose QC20i's with me to my dad's place (he only lost power for 4 hours) and I gotta say I am very impressed with them. They sound pretty good (best Bose headphones I've heard yet) and their noise cancelling circuitry is simply astounding! I thought the QC15s did a good job, but these are on another level.
Are you in the GTA? My parents are downtown and it seemed like they were the only ones with power. I escaped to PEI for Christmas so I missed it all :)
