For images that are not creative in the sense of being a product of non-trivial "skill and judgment" as discussed below.

Unlike other common law countries, Canada's threshold of originality veers closer to that of the United States. CCH Canadian Ltd. v. Law Society of Upper Canada explicitly rejected the "sweat of the brow" doctrine for being too low of a standard, but at the same time, stated that the creativity standards for originality were too high:

A creativity standard implies that something must be novel or non-obvious — concepts more properly associated with patent law than copyright law. And for these reasons, I conclude that an “original” work under the Copyright Act is one that originates from an author and is not copied from another work. That alone, however, is not sufficient to find that something is original. In addition, an original work must be the product of an author’s exercise of skill and judgment. The exercise of skill and judgment required to produce the work must not be so trivial that it could be characterized as a purely mechanical exercise."

The same case also stated:

For a work to be “original” within the meaning of the Copyright Act, it must be more than a mere copy of another work. At the same time, it need not be creative, in the sense of being novel or unique. What is required to attract copyright protection in the expression of an idea is an exercise of skill and judgment. By skill, I mean the use of one’s knowledge, developed aptitude or practised ability in producing the work. By judgment, I mean the use of one’s capacity for discernment or ability to form an opinion or evaluation by comparing different possible options in producing the work. This exercise of skill and judgment will necessarily involve intellectual effort.

There are many logos and trademarks in the United States that are not protected by copyright because they are below the threshold of originality required for copyright protection. There are some cases that even logos and trademarks that have been judged to be copyrighted in foreign countries have also been judged not to be copyrighted in the United States. However, some logos and trademarks are copyrighted in the United States. See COM:CRT/United States#Threshold of originality for more information.
