“ The author died before 1972, meaning that copyright on that author's works expired before the Canadian copyright term was extended non-retroactively from 50 to 70 years on 30 December 2022. The longest-living author of this work died in 1945, so this work is in the public domain in countries and areas where the copyright term is the author's life plus 78 years or less. This work may be in the public domain in countries and areas with longer native copyright terms that apply the rule of the shorter term to foreign works. ”
