What is the test for freedom of religion?

…”[Freedom] of religion ensures that every individual must be free to hold and to manifest without State interference those beliefs and opinions dictated by one’s conscience. This freedom is not unlimited, however, and is restricted by the right of others to hold and to manifest beliefs and opinions of their own, and to be free from injury from the exercise of the freedom of religion of others. Freedom of religion is subject to such limitations as are necessary to protect public safety, order, health or morals and the fundamental rights and freedoms of others.” Ross v. New Brunswick School District No. 15, [1996] 1 SCR 825, 1996 CanLII 237 (SCC), para. 72
