No Google in Toronto

Someone is always taking the opportunity to talk about how nice it is to work at Google, so I'm always surprised that they don't have a Toronto office (actually, they do have one, but they don't seem to hire software developers). Although I don't have the stats to back it up, Toronto's probably got the most software developers of any Canadian city, but ... no Google. Why is that, exactly?

Hey, Google, open a Toronto office. :)
