â Donald J. Trump (@realDonaldTrump) December 25, 2017. Yeah, so, why did he like that subtweet of the Grinchâs tiny heart?

If the Copyright Office has no confirmation that a composer or song-writer is still living and it has been 75 years since the first copyright protection order was granted, or 100 years since the recognized creation date of the piece, it becomes public domain.
Public Domain in Canada. In Canada, the copyright for a work usually expires 50 years after the death of the creator, at the end of the relevant calendar year. Determining whether a work is in the Public Domain can be complicated, however, as the duration of copyright differs depending on a work's authorship and format.
