The on-reserve delivery is normally provided by the groups that have been developed over the last 20 years. Some of them have sophisticated processes whereby they can deliver interventions, although not much in the way of prevention.
Others are still in the embryonic stage, even after 20 years, and haven't really reached a level of maturity to deliver services. The reasons are that it's been quite difficult for them to, first of all, get the funding, and secondly, to recruit the people who can actually deliver on a local on-reserve type situation.
When it comes to in the cities or off reserve, there are entities that provide appropriate support--other than the provincial government, the ministry--in a similar way to the on-reserve area, but there are some difficulties and problems with that. So what you find is that, initially, there is an attempt to provide the right service provider. If they can't provide the right service provider, then they default to the provincial government, the ministry, if you will, to provide the support services they need.
