Volumes 1 through 48N1 are open access; Volume 49 (2022), the current volume, is available by subscription, unless authors have arranged immediate open access. All other papers will become "open access" one year after publication.

Geoscience Canada is moving toward providing authors with the opportunity to comply with "open access" requirements.  Effective with Volume 44 (2017), papers published in the journal will be "open access" 12 months after they appear in the journal.  If authors want immediate "open access", the charge will be $500 + $50/per page.
