Actually, I wasn't particularly thinking about existing legislation.
I think there is always a danger that if employing a woman is, for whatever reason, more expensive than employing a man, fairness may not be the first thought on the employer's mind. I raise this as a caution. If there were to be any national program for maternity, the cost should be independent of whether or not the employer chooses to employ women. The employer shouldn't be allowed to duck out by saying, “We will only have men, so we won't have those additional costs.”
I know that in Quebec that isn't the case. The employer pays regardless of the way his workforce is constructed. This is something that, right from the beginning of these discussions, I would suggest you keep in mind.
