From the DOJ technical paper at
http://www.justice.gc.ca/eng/rp-pr/other-autre/protect/p1.html
The following activities have been found to constitute a sexual service or an act of prostitution, if provided in return for some form of consideration:
lap-dancing, which involves sitting in the client’s lap and simulating sexual intercourse;[SUP][31][/SUP] masturbation of a client in the context of a massage parlour, whether or not the client climaxes;
[SUP][32][/SUP] and, sado-masochistic activities, provided that the acts can be considered to be sexually stimulating/gratifying.
[SUP][33][/SUP] However, jurisprudence is clear that neither acts related to the production of pornography,
[SUP][34][/SUP] nor stripping
[SUP][35][/SUP] meet the test. In most cases, physical contact, or sexual interaction, between the person providing the service and the person receiving it is required; however, acts for which consideration is provided that take place in a private room in a club and that are sexual in nature, but do not involve physical contact between the “client” and “performer”, such as self-masturbation, have been found to constitute prostitution.
