If you mean provinces in Canada's context, then no, the number of provinces does not fit on one hand. In fact it barely fits on two, and that's only if you don't count the territories as well.

A bigger factor is that the Canadian prohibition was only controlled at the federal level in the first place, like all Canadian criminal law, so only the federal government had to legislate to change it. The provinces have however done lots of subsequent legislation to regulate the details (e.g. distribution channels and the exact minimum age limit) in a wide variety of ways.
