UNITED NATIONS ARTICLE 18

Freedom of religion or belief is guaranteed by article 18 of the Universal Declaration of Human Rights, article 18 of the International Covenant on Civil and Political Rights and the Declaration on the Elimination of All Forms of Intolerance and of Discrimination Based on Religion or Belief.

CANADIAN CHARTER OF HUMAN RIGHTS AND FREEDOMS
Section 2.

Everyone has the following fundamental freedoms:
(a) freedom of conscience and religion;
(b) freedom of thought, belief, opinion and expression, including freedom of the press and other media of communication;
(c) freedom of peaceful assembly; and
(d) Freedom of association.
Under section 2 of the Charter, Canadians are free to follow the religion of their choice. In addition, they are guaranteed freedom of thought, belief and expression. Since the media are an important means for communicating thoughts and ideas, the Charter protects the right of the press and other media to speak out. Our right to gather and act in peaceful groups is also protected, as is our right to belong to an association like a trade union.

It’s important to note, this does not just speak to Easter weekend or the Christian religion, but all faiths and religious holidays.
