I'm not able to answer why in Quebec specifically. What we do know through our federal, provincial, and territorial work is that there are programs in a variety of provinces to support women in politics. Alberta's government with its supportive program aims to increase gender parity in elected positions through training, mentoring, or communities of practice.
The Nova Scotia Advisory Council on the Status of Women has something called the Campaign School for Women: Leaders in Action. It's a course that prepares graduates to run for public office, organize campaigns, or pursue non-elected political roles.
The Government of New Brunswick has changed the way political parties receive government funds.
There are different initiatives across the country. Interestingly, for our next federal-provincial-territorial meeting in Yukon, the Northwest Territories minister for the status of women has been asking that women in leadership, women in politics be one of the issues that we speak about.
