In Nova Scotia, particularly in Halifax, there was, until the 1980s, a very distinct system of gender-based laws were in effect for decades. Taverns, bars, halls, and other classifications differentiated whether it was exclusively for men or women, men with invited women, vice versa, or mixed. After this fell by the wayside, there was the issue of water closets. This led to many taverns adding on "powder rooms"; sometimes they were constructed later, or used parts of kitchens or upstairs halls, if plumbing allowed. This was also true of conversions in former "sitting rooms", for men's facilities.
