Google's Street View is in the process of collecting pictures of Montreal streets. When complete, Google Maps will be able to show street-level photos of major cities in Canada like it does for New York and San Francisco.
Street View works by having someone in a car with lots of cameras on the roof drive through the city and take pictures. They're then thrown into a giant database which creates a street view you can move around in.
Of course, if you happen to be walking along a street when the car passes by, you'll become a permanent part of the view of that street. And that can lead to some embarrassing pictures.
Canada's privacy commissioner has already raised concerns that, because Google doesn't ask permission before taking photos, they might be violating Canada's privacy laws.
