What I suggested is that where someone is deceiving the public by affixing as CSA logo, they are trying to tell the public that it is of a certain quality when it is not. Again, that is not a trademark issue, and once you move into the realm of stronger protection for trademark and copyright, there are other consequences, because once that legislation gets established, the impact is not so narrowly tailored to your son's pyjamas but has an impact on a broad range of activities, some of which may be seen as negative.
