Important information about benefits for Indigenous Peoples

If you are Indigenous there are many things that affect the benefits you can get and the dollar amounts you can get from them. These include the agreements your band or governing body has with provincial, territorial, and federal governments. Before applying to any benefits, you should speak with your governing body, if applicable.

AFOA Canada and Prosper Canada are currently seeking funding to develop an online tool that serves the needs of Indigenous people living in Canada.
