Well, 20 or 25 years ago, under the Criminal Code, men were allowed to rape their wives.
Aboriginal women who married non-aboriginal men lost their status.
Rape victims had to deal with discriminatory provisions on how to prove whether they had effectively been raped or whether they had consented to sexual assault. In the 1990s defence attorneys started accessing confidential files of sexual assault survivors to discredit them.
Immigration provisions were explicitly sexist against immigrant women on all sorts of levels. Sponsored women would still be sponsored for over ten years. Now it's been reduced to three years.
Matrimonial property would not have been redefined in such an egalitarian way in family law.
The Employment Equity Act wouldn't exist at the federal level.
I could go on, but I think I've made my point.
