We came across this article in the Vancouver Sun that confirms that women are leaving the legal profession in Canada at a faster pace than men. 

In fact, women are leaving the profession at a rate 2 to 3 times higher than their male counterparts.

It cites a number of factors for the discrepancy, including the unavailability of support and benefits such as part-time partnerships, part-time employment, predictable hours, job sharing and flexibility in hours.
