One example has already been mentioned: Clare's Law. I believe it makes a difference. Many provinces are now adopting it.
There are many local initiatives, including things like Ask for Angela, which is a prevention program. It's more to prevent sexual assault, but it is also important.
Safe houses are another model that has been implemented in different areas. Depending on what the needs are in northern communities like Nunavut.... Safe houses are extremely important because there are so few shelters and there is so much distance between shelters.
I think those examples also depend a bit on the local community and the needs identified there.
