The past quarter-century has seen substantial change in the social safety nets for families with children in the United States and Canada. Both countries have moved away from cash welfare, but the United States has relied more on work requirements. We examine the implications for the employment and poverty of low-educated single mothers. We find that employment improved substantially in both countries, absolutely and relative to a control group of single women without children. Poverty rates also declined in both countries, with more of the decline coming through market income in the United States and benefit income in Canada.

We investigate how reforms of Canada’s child allowances affected household poverty and maternal employment—the 2015 increase and expansion of the Universal Child Care Benefit and the 2016 introduction of a new Canada Child Benefit (CCB). We document that both reforms reduced child poverty, although the CCB had greater effect. By 2018, we estimate that the CCB reduced poverty by 11% in families headed by a single mother and by nearly 17% in two-parent families. We find no evidence, on either the extensive or the intensive margin, of a negative labor supply response to either of the program reforms.
