Given that this is Canada, the first and fourth amendments don't come into the discussion.
Canada's rights are in the Charter of Rights and Freedoms, and they aren't absolute.
Part 1, Section 1.
The Canadian Charter of Rights and Freedoms guarantees the rights and freedoms set out in it subject only to such reasonable limits prescribed by law as can be demonstrably justified in a free and democratic society.
Subject to that, we get 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.
