sentences:  Trudeau's 1980 observation that if Canada is divisible, Quebec is also divisible, was made on the eve of a referendum in which he was attempting to encourage voters to cast their ballots against secession.The first book on the subject, and the one which gave its name to the movement, was 1980's "Partition, the Price of Quebec's Independence", by Lionel Albert and William Shaw.The title of this book makes clear its intention to use the threat of territorial losses to dissuade Quebecers from voting in favour of secession.
