Okay - a bit more about the one poll option. It came to mind because there was a story in the media about this recently:
CBC News - Quebec students must take ethics-religion course
Short version, public schools in Quebec have a "religion and ethics" course in their curriculum in most years of elementary and high school.
It doesn't indoctrinate students in any of the religions covered or advocate one religion ahead of any others, but it does provide an overview of what various world religions believe. The course is mandatory for all students.
Recently, a religious couple whose child was enrolled in a Quebec public school (and therefore was taking these classes) launched a legal challenge, arguing that teaching their child about other religions as well as presenting the material in a way that put their own religion on an equal standing with all the others was a violation of their freedom of religion guaranteed under the Charter of Rights and Freedoms.
So... that's kinda what I was thinking when I included the last option in the poll.
