I think of programs that the CMHA runs, for example. The CMHA is often the first stop for people searching for mental health resources in their community.
As to looking for certifications, we offer a peer support certification. There are also other certifications. Certainly the Canadian Psychological Association and other registered professions have the credentials to provide you with the supports you need.
There is a lot of online information as well. I would turn to the new government application. That actually has evidenced-based tools and resources that can be used.
