 Throughout this time, Dr. Douglas maintained an interest in Canadian history and heritage.He wrote several books on the subject in his lifetime, namely "Canadian Independence, Old France in the New World," and "New England and New France—Contrasts and Parallels in Colonial History".In addition to bailing Queen’s University out of a financial crisis with approximately a million dollars from his own pocket, Douglas also established the first chair in Canadian and Colonial History there in 1910.
