Imagine Native is a Toronto based Indigenous run media company. They are a non-profit society with the aim of distributing a breadth of Indigenous created media content. In addition to organizing film festivals and screenings, they offer workshops and resources for emerging artists (http://www.imaginenative.org)
Hidden in their publication page, there are numerous topical essays related to arts and technology. This content is worth a lengthy glance. They also offer a quick preview for their film festival content.
This is a great resource to find films that are not advertised or supported by large format media.
