I cannot really answer the question as is, in terms of what the political reasons are for there being no legislation tabled. However, my understanding of the matter is that there is a fairly obvious consensus on the issue of penalties associated with the failure to participate in the census. The Canadian government would be ill-advised to send someone to prison for this reason. I have not met anyone who was in favour of this kind of action. I think it is clear why these penalties have become obsolete. There should perhaps be a more clear-cut bill. When I say that the census should be mandatory, that implies that we look at consequences, but not as serious as jail time.
