I came upon your enquirey purely by accident while browsing the web this morning. Although I don't believe I can help you directly I believe I can direct you to my cousin Steven Dow of Port Daniel Gaspe. He has done extensive research into his own Dow roots and even has the entry papers of his grand father (or Great grand father) when he immigrated to canada. (I believe there is a William and a John Dow way back in the family tree and Nova Scotia and Gaspe are so near that they are mostly cousins a few time removed). I haven't kept in touch with Steven...he is actually my second cousin. But I'm sure you can easily find him in the white pagea and I bet he'll be more than happy to share with you what he knows about the Dow family in the Maritimes.
