This direct from the charter.
1. Freedom of Conscience and Religion (Section 2(a))
Before the Charter came into force, there was no express protection for freedom of religion under the Constitution Act, 1867. Some limited protection was, however, given to denominational schools in section 93 of that Act. Specific legislative jurisdiction with respect to religion is not dealt with in the Constitution Act, 1867 and the courts have had to characterize laws touching religion as coming either within section 92 or section 91 of that Act. The pre-Charter cases in this area mainly dealt with challenges by merchants to various Sunday closing laws.
The fact that "conscience" has been separated out from "religion" led to comments that the Charter might constitutionalize the right of civil disobedience when the route of opposition to law is sufficiently the product of an individual's deeply held system of moral beliefs, whether or not these are grounded in considerations normally regarded as religious. In R. v. Big M Drug Mart, the Supreme Court of Canada indicated that the freedom of conscience safeguarded by this provision relates to freedom of conscience in matters of religion. The paragraph protects against all state-imposed burdens on the exercise of religious beliefs, whether direct or indirect, intentional or unintentional, foreseeable or unforeseeable, provided they cannot be regarded as merely trivial or insubstantial.
I The court concluded that since the enactment of the Charter it has become the right of every Canadian to work out his or her own religious obligations, if any, and it is not for the state to dictate otherwise.
And finally! First Nations are not first among equals despite the hyperbole otherwise. There is no way in hell you are going to give a muslim kid a bar mitzvah for the sake of education.
