Generally, authors must seek permissions if they reproduce in their work (article, book, McGill thesis, etc.) third-party content: graphs, charts, figures, images, etc. that is under copyright protection.
In case if the third-party work was released as open access under a Creative Commons licence, its content can be reused as long as the terms of the licence are followed.
To obtain permissions to reproduce materials (images, photos, plans, charts, etc.) published in a book, in most cases, publishers have to be contacted directly (via email).
