Some people say that the Canadian government places no restrictions on abortion - e.g. Wikipedia:
Canada is one of only a few nations with no legal restrictions on abortion.
Yet you do see some restrictions, only those restrictions are targetted at limiting public debate rather than limiting the number of such procedures - i.e. things like bubble zones around abortion clinics, limits on the ability to provide counselling, the number of protestors (where they're allowed), and the signs that they're allowed to carry.
Now it seems that the Ontario government is trying to further keep information regarding abortion out of the public eye. Here's a bit from The National Post:
Questioned as to why it had begun making it harder to obtain figures related to the number of abortions performed in the province, a practice that has been increasingly evident to researchers for some time, the provincial Ministry of Health responded in a statement to the National Post: 'Records relating to abortion services are highly sensitive and that is why a decision was made to exempt these records [from the Freedom of Information and Protection of Privacy Act]'
The National Post columnist's response included identification of a few other sensitive topics:
figures on gun crime, incest, spousal abuse, child abuse, rape, infanticide – crime of all sorts, as a matter of fact. You’d also have to concede that information related to racial, cultural or ethnic issues can be, and often is, highly sensitive. Is anything more delicate, given the cultural, religious and political ramifications, than the issue of honour killings? Should Ontarians be allowed access to figures related to immigration, given how touchy the matter can be? Perhaps data related to education and health care should be lumped in as well, given the heated arguments that often break out over policies and practices related to those topics. The government has seen fit to exclude none of those from its legislation, however. Only abortion.
As the article notes that safety considerations shouldn't be effected by mere numbers as people already know where abortion clinics are and no names of the women who've had abortions would have been released. The article's conclusion:
it is difficult not to conclude that the government simply wants to make an exception in the case of abortion in order to prevent researchers or opponents from continuing to assemble the kind of numbers that may make some Canadians uncomfortable. ... Singling out abortion as the only exception to the rule of public access suggests the government’s real motivation is a desire to stifle debate and avoid having to answer the difficult questions that arise from Canada’s easy and unquestioning approach to the provision of abortion.
