In accordance with the CF Dress Regs Manual Section 2 (page 2-2-6) - Appearance - Body Adornment para 9. it states:
"Members shall not acquire visible tattoos that could be deemed to be offensive (e.g., pornographic,
blasphemous, racist) or otherwise reflect discredit on the CF. Visible and non-visible body piercing
adornments, with the exception of women's earrings and ear sleepers described in sub-paragraph 6.a.,
shall not be worn by members either in uniform or on duty in civilian clothing. The meaning of the term â Å“on
dutyâ ?, for purposes of dress and appearance, is Interpreted in Chapter 1, paragraph 25."

Once enrolled though, the above reference stands.
