In Canada, the creation of a work engages copyright protection even without registration. Refer to the textbook to identify the FALSE statement concerning copyright registration and possible infringements. O a.

Non-commercial users are permitted to use copyrighted material in remixed musical performances and mashups (where some copyrighted material is incorporated into a video) under the "YouTube exception". O d. One can notify others and deter infringement by marking the copyrighted product with the letter "C" enclosed in a circle followed by the name of the owner
