Looking for suggestions.

Hello all, I am looking for some support here. My sister has been behaving weird for the past few weeks. At first, we were confused, we didn't know what was going on. Recently we found out that she has been abusing drugs. We have decided to get her some medical support. Can someone suggest a good treatment center we can consider? One of my friends suggested to me this drug addiction recovery center in Toronto. Does anyone know about them and how they work? Kindly share your suggestions. Thank you.
