Thank you.
There is U.S. based research on exactly this topic, and the finding that you described is echoed in that research, which indicates that “women experience a perfect storm in their mid- to late 30s. They hit serious career hurdles at the same time that family pressures ratchet up.”
One of the recommendations of the report is that companies that step in with targeted support at this time—and they call it a “fight or flight moment”—may be able to lower the female attrition rate significantly.
So there is some great work that's been done in the U.S. that could certainly assist in our better understanding what the challenges are, how this results, and then what actions might need to take place, understanding that it is from the U.S. context and that the research we encouraged earlier regarding Canada would be better able to reflect the Canadian context.
