When it comes to women in the workforce, Canada and the U.S. are beginning to look like night and day. In the 1990s, the share of women working in Canada was the same as the share in the U.S., with about 77 per cent of women aged 25 to 54 in the workforce.

But then things began to diverge. In Canada, the share of women kept rising, reaching highs above 81 per cent by 2013, Statistics Canada said in a study released this week. But in the U.S., it has been falling since 1999, and is now below 74 per cent. One reason for the divergence could be Canada’s much more generous maternity leave policy. In a study issued late last year, TD Economics noted that Canada expanded maternity leave policies at the turn of the century, about the same time that women’s participation rates began to diverge.

Even though Canadian millennials were hit harder than U.S. ones in the Great Recession, they recovered faster thanks in part to a higher rate of participation by women, it said.
