Bill C-61 was introduced on June 12, 2008, shortly before the Parliamentary summer recess. The legislation is intended to bring Canada up to date with international treaty obligations and address new technologies, especially the digital reproduction and distribution of copyrighted materials.
The considerable opposition to Bill C-61 has focused on the protection of technological protection measures (TPMs, also known as digital rights management or DRM), digital locks intended to allow rights holders to control how their work is copied and distributed and to limit infringing use of these works. However, in doing so, TPMs prevent a myriad of legitimate uses, such as time and format shifting, or copies for personal use, educational purposes, review purposes, research, and parody. C-61 prohibits the removal of TPMs except under very limited circumstances, along with the creation and distribution of software or hardware tools that removes TPMs.
