Yellow Pages Canada maps use little numbered darts to indicate location on the map in cross-reference to the listings. Initial scales are seemingly out of whack and once again the power of advertising logic in search prevails - when you search for furniture you must really want baby carriages and rugs.
Here's YellowBot's Large Map View using Google. Not a lot of additional information about the listings is provided in the side bar. Lack of a phone number at least makes this view a little unusable.
Live 1-Click Directions is an interesting innovation. It doesn't require the user to enter a specific starting location. The user just has to tell the system what direction he or she is coming from. The site uses the closest major highway exits as the "starting location" assuming the user knows how to get to the major highway from wherever he or she is.
Live provides refinement by Neighborhood via a pop-out in the results listing. No indication of the boundaries for any neighborhood seems to appear on the map.
Live provides some support for handling multiple businesses located at the same address. This is useful but more could be done particularly when it comes to a whole shopping mall.
Live Maps provide the user with 2D and 3D views (when using a Windows machine), as well as road, aerial, and birdseye views. Traffic information is also available.
Live detail fly-outs on the map provide basic listing information along with send functionality (mobile and email), driving directions, adding listing to a collection, and zoom.
Pages Jaunes doesn't seem to have individual landing pages for their businesses. You can get a map view, directions, aerial views, photos and search nearby but no landing page. They use the listing information to set a 'context' to the current view along with a call to Find Nearby.
