Or, almost not.
A new study from Statistics Canada's Social Trends, Till death do us part? The risk of first and second marriage dissolution (by Warren Clark and Susan Crompton) [also available as a pdf file] finds that most people who marry do not divorce; that 46% of those whose first marriage ends will remarry; but that fewer than 1% of the "ever married population" indulge in a third marriage. There's much more in the report to interest family lawyers. And spouses.
