As the other witnesses have said, I think it depends on what your measures of success are. Obviously, the most important one is the overall objective of being a useful tool for investigating crimes. I defer to my police colleagues on that matter at this point.
Other measures we look at, for example, include whether the legislation has withstood challenges in the courts. So far, the answer is yes. That's an important factor. You want to have a model that is going to be workable and not be out of business the next day.
We look at a measure of success: is it meeting the needs of all parts of the country? Everyone shares the same objective. There's simply no debate about the objective of protecting vulnerable citizens. Some features may perhaps be more appropriate or more useful for a larger province than a smaller province or for one area of the country with a different crime pattern than another area of the country. Those are matters that we, as officials, take into account when developing our advice. You can have a model that may be very good but is not suitable for the north as compared to the south.
Whatever model of registry Parliament chooses, of course, you want it to be the best one possible. There are many different models of sex offender registries, and you can look at the U.S. for that.
