C-15, r. 4 - Code of ethics of chemists
13. The chemist shall endeavour to establish a relationship of mutual confidence between the client and himself. To that end, he shall, in particular:
(1) refrain from practising his profession in an impersonal manner;
(2) respect his client’s scale of values and personal convictions, taking into account, however, the responsibilities which are his, particularly the protection of the public.
