I'd say that most of the change on this front has been at the diocese level, not top-down from the Vatican. In fact, the Vatican has sometimes gotten in the way, as it did in the late 90s with its letter to the Irish archbishops when it told them (shamefully, IMO) to scale back their anti-abuse policy to bring it in line with canon law.AMEN BROTHER!
One of the things that anti Catholic people refuse to grasp is that the church, in it's own way, has made serious strides towards elimination of that evil.
Could they do better and more? Sure. That will always be true. But the equation of good to abuse has altered hugely in recent years, especially concerning children. And it wasn't always some Vatican pronouncements, much of the change was bottom up. Parishioners have a ton of influence in the local doings of the church, at least here in the USA. The pressure for reform was huge and couldn't be swept under the rug.

At this point, I'd say that the archdiocese of Toronto's anti-abuse policies are responsible and in line with those of other youth-oriented organizations. Where some confusion still exists, IMO, is that there are cases where a parish can be within the physical boundaries of a diocese but be run by a religious order; these parishes are subject to the rules of the order, not the diocese, and can be more opaque as to what their policies are.
