You want to phone all residents living along a city block in Montreal to notify them of manhole repair work planned in two weeks.
Solution:
Street Atlas USA 2009 PLUS contains business and residential phone listings for Canada as well as the U.S., so you simply right-click on the block in question and bring up listings with addresses and phone numbers for everyone living on the block or street. You make phone calls notifying each resident of the scheduled repair work and expected completion date.
