shows private property in such a manner that a viewer of the photograph can identify the owner of the property, the ASMP (American Society of Media Photographers, Inc.) recommends that a property release should be used if the photograph is to be used for advertising or commercial purposes. According to the ASMP, a property release may be a requirement in such a situation. Other issues Photographing or videoing accident scenes and law enforcement or emergency activities is usually legal, as long as a person does not interfere with their response or situation. *Any filming with the intent of doing unlawful harm against a subject may be a violation of the law in itself. Canada Federal legislation governs the questions of copyright and criminal offences with respect to photography. Otherwise, the common law (in Quebec, the Civil Code of Quebec), generally determines when photography can take place. The Copyright Act provides that the duration of copyright for a photograph is the life of the author plus 50 years. Freedom of panorama is also allowed, with respect to photographs of sculptures and architectural works, and there is also protection for those who "incidentally and not deliberately include a work or other subject-matter in another work or other subject-matter." The Criminal Code provides for punishment of various offences, including voyeurism, child pornography, trespassing at night, and paparazzi behaviour. The law of defamation, trespass and privacy is governed at the provincial level. The common-law provinces of British Columbia, Manitoba, Newfoundland and Labrador, Ontario and Saskatchewan have enacted privacy legislation dealing with personality rights, which supplement the law of trespass. In Quebec, the Civil Code goes further by specifying that "keeping ... private life under observation by any means" constitutes an additional ground of invasion of privacy. In Aubry v Éditions Vice-Versa Inc, the Supreme Court of Canada held that, because of that, supplemented by Quebec's Charter of Human Rights and Freedoms privacy provisions, a photographer can take photographs in public places but may not publish them unless permission has been obtained from the subject, except where the subject appears in an incidental manner, or whose professional success depends on public opinion.
