In addition to asking questions here, there are three good sources of information about canoe restoration that you would do well to get, or at least look at before undertaking any repair or restoration of your canoe, -- "The Wood and Canvas Canoe: A Complete Guide to its History, Construction, Restoration, and Maintenance" by Rollin Thurlow and Jerry Stelmok, and/or "Building the Maine Guide Canoe" by Jerry Stelmok.
The first is often called the "bible" of canoe repair, restoration, and maintenance; the second is an excellent study of the wooden/canvas canoe and its construction, and the third is a great history of the company and its canoes. These are available from the WCHA store, are often on eBay, or from Amazon.
