This paper examines possible determinants of models of the division of earning and caring activities in Canadian couples. Using the General Social Survey on Time Use, we identify five models of the division of work: complementary-traditional, complementary-gender-reversed, women's double burden, men's double burden, and shared roles. While the complementary-traditional model is declining, it still represents a third of couples. Women's double burden is the second largest category, representing 27 percent of couples in 2005, with men's double burden representing another 11 percent.
