In May of 2001, I was exploring an abandoned garment factory on Duke St. in Kitchener, when I found copies of these two regulations. I've put copies here for those who are interested.
It's interesting to note that overtime isn't really defined, except as more than “the normal number of hours established by custom by an employer”. As well, women subject to these orders were paid for overtime at the normal hourly rate (order 5.1). (There is, however, a reference to another regulation governing the hours of work in order 15.)
It's a little difficult to directly compare the minimum wage for men and women, since legislation for women was introduced first, as it was thought that they needed more protection. At the time these laws were written, wage protection legistation did exist for men, but it didn't actually set a minimum legal wage. When minimum wages for men were legislated later on, they were higher for men. What follows are brief exerpts from two papers on this topic, which give an overview of the history of this issue.
