Erm, no... in Canada the voltage can be anything, just as it can in any other part of the world. Just because the standard AC outlet hovers around 120V, does not mean they didn't have two (or more) phases available. 208V or 240V are just as likely to be available as 120V in North America, depending upon the venue.
And if I am not mistaken, SC07 took place in Reno, NV... nowhere near Canada.
brainwrong is right... 26A means nothing out of context. Maybe it's 26A on the 5V rail - i.e. one standard power supply. We may never know.
