Public domain

This page helps users determine whether a given work is in the public domain in Canada where this site is hosted. The Canadian Intellectual Property Office has A Guide to Copyrights. For a visualization see an archived (no longer current) version of the Canadian public domain flowchart. See the full text of Canada's Copyright Act. If a work is in the public domain in the USA, please post it on Wikisource per its copyright policy.

Text and commentary

Only sections relevant to the operation of Wikilivres will be considered here. Unless otherwise stated, all references are to the Copyright Act.

Language equivalence — Constitution Act, Subsection 18 (1)

The statutes, records and journals of Parliament shall be printed and published in English and French and both language versions are equally authoritative.

Les lois, les archives, les comptes rendus et les procès-verbaux du Parlement sont imprimés et publiés en français et en anglais, les deux versions des lois ayant également force de loi et celles des autres documents ayant même valeur.

This is an imprtant principle in applying Canadian law generally.

What is copyright — Subsection 3 (1)

For the purposes of this Act, “copyright”, in relation to a work, means the sole right to produce or reproduce the work or any substantial part thereof in any material form whatever,...

Le droit d’auteur sur l’oeuvre comporte le droit exclusif de produire ou reproduire la totalité ou une partie importante de l’oeuvre, sous une forme matérielle quelconque,...

This sets up somewhat of an equivalence between "copyright" and "droit d'auteur".

It's also important to take not of the term "substantial part". This allows insubstantial parts to be used, but "substantial" is still open to definition.
