I think that this conversation is getting way off track.
The original question was about what type of adapter on needs to be able to plug into a power mains in Canada.
One smart answer was the picture of the sockets available.
I suggested that someone in Montréal see if he collect a bunch of power cords that I felt that people might want to donate.
That is all. I assume that the wikimedians travelling to Canada know about the voltage issues, they just want to be able to plug their modern computer into the room socket.
