That's the only one of that sort that I'm aware of. I believe there also have been some bills studied recently by the legislature of Scotland, and probably also in a number of jurisdictions in Australia. I haven't looked at those very closely. There are also always a handful under debate in legislatures in the various U.S. states.
There's quite a number. If one goes back 10 years or so, one could find quite a number.
Of course, in the Parliament of Canada there have been private members' bills recently. Bill S-225 was introduced in the Senate last session. That's another model you could look at.
