A lot of times for promotion you also need to have ticks in the box. In certain occupations, without a deployment overseas it's very hard to go beyond, say, the rank of major. The other factor is specific training, specific professional military qualifications that one might need.
As long as the system is set up so that you need those ticks in the box and it's not easy for every female officer or female NCM to get those ticks in the box, it is going to be more difficult for them to be promoted by a promotion board when it's all about points at the end of the day.
Is the system perfect? Probably not, but if you have no deployments, if you don't have the ticks in the box for your PME, your professional military education and other training, it's going to be very hard for you as a female to be moved upward, in addition to the geographic issues that Dr. Okros talked about.
As a way to offset that, there are some professional military education qualifications that can be obtained through distance learning. That's one way, so that a woman who has young children doesn't have to spend, say, one year at the Canadian Forces College in Toronto to complete a qualification in order to go from major to lieutenant-colonel.
Those kinds of things need to be looked at: What are the criteria for promotion, and do they need to stay like that?
