My good friend Emma Julien continued the tradition of updating this database of Canadian Folk Festivals. You can download an Excel version which you can add to/edit, or a simple pdf version. And I would encourage you to please consider making a donation. It takes many hours of research to update this free resource.
Download the database by following this link: http://www.emmajulien.com/
It is a powerful resource for any folk/roots artist inside our outside of Canada.
