SYNOPSIS
Criminal Code of Canada
General Canadian Human Rights Act usage:
Canadian Human Right Commission (Supreme Court Decision)
It is only possible to challenge legislation specifically (such as challenging a Provincial Service Dog Act) if the Human Rights Act of the province specifically indicates that it is supreme, or paramount. Even with such a declaration, depending how Provincial Courts interpret this above decision, challenging legislation at a Human Rights Tribunal may not be possible. Challenges against the wording of legislation could then only occur at a costly Supreme/Superior court hearing.
