Bestselling author Ken Mcgoogan plunges into the perpetual debate about Canadian roots and identity: who do we think we are? He argues that Canadians have never investigated the demographic reality that informs this book - the fact that more than nine million Canadians claim Scottish or Irish heritage. Did the ancestors of more than one quarter of our population arrive without cultural baggage? No history, no values, no vision? Impossible. Ken Mcgoogan is the best-selling author of "50 Canadians Who Changed the World."
