Actually, this is not quite correct. In larger urban areas people must
dial the 10 digit number without the 1. This is because they may have
several area codes within their local called area. Here in Houston we
have 713, 281 and 832. In Toronto they have 416, 905 and a new third
that I don't know.

The 1 is only dialed to a known long distance number.
