. . . but interesting nonetheless. Geograph is a UK site that seeks to collect a photographic image of every 1 km square area in the British Isles. The idea is that each photograph is representative of that square kilometre. So far, about 9,000 of the 241,000 possible squares have been photographed. A map viewer allows the user to navigate about the country and zoom in. Unfortunately, there is not data on the map except for the location of the photographs so the user has to rely on memory as to where cities or features are located.

A similar exercise for Canada, though not impossible, would probably be too daunting. You'd be better off going to the Degree Confluence Project that seeks to photograph each confluence of latitude lines with longitude lines.
