Date Determination: There is no date apparent in this map.  The maps used by British American at this time were virtually the same maps published by the Ontario Government.  So a comparison of the Official Ontario Road Map to the British American map can help determine the date of the B - A map.  It has been determined that there are numerous similarities between this map and the 1929 - 1930 Official Road Map of Ontario.  The Windsor-Detroit bridge is shown on this map - which is useful in dating. The message from George Henry is the same shown on the 1929-30 Ontario Official Map. The road between Cochrane and Kapuskasing is shown as under construction, again pinning down the date through the process of elimination.
