Mapmaker is the the tool from Google Maps where you can add information - much like you can in Open Streetmaps. By looking at the list of countires and regions where this tool is available I can see a pattern - regions with low density of population or available data. But to be honest - there are areas even in high population density countries like Italy and Germany where Google Maps still lacks. While I hope they will release this tools for those areas as well I will try to make the map of Canada better :)
