This paper examines the determinants of union dissolution among first marriage, second
marriage, and common-law unions via an event history analysis of the fourth panel of the
Survey of Labour and Income Dynamics (SLID). Results suggest that unemployment and
other potentially challenging employment situations are associated with higher odds of dissolution,
among first marriage unions in particular. The factors that predict union dissolution are found to
differ, both across union types and within common-law unions by region (Quebec versus elsewhere
in Canada).
