A controversial secularism law in Quebec is heading to Canada's Supreme Court - but the outcome will impact much more than religious expression in Canada, legal experts say.
The case has the potential to test national unity and the balance between courts and elected officials. This case is probably going to be the most important constitutional case in a generation, said Christine Van Geyn, executive director at the Canadian Constitution Foundation.
At the heart of the case is Bill 21, which bars civil servants like judges, police officers, and teachers from wearing religious symbols at work. It was passed in 2019 by the governing Coalition Avenir Quebec (CAQ). However, to withstand legal challenges, legislators employed a unique Canadian invention, the controversial notwithstanding clause. That legal loophole allows governments to override certain constitutional rights, including freedom of religion and equality rights.
The Canadian Civil Liberties Association (CCLA) called Quebec's arguments in court spine-chilling. They highlighted the implications of using the clause to restrict fundamental rights and freedoms, questioning whether it could also be used to ban abortion or to criminalize political speech.
On Monday, the court will begin four days of hearings on a constitutional challenge to Bill 21, with more than 50 interveners including the federal government.
As in France, Quebec's state secularism - or laïcité - is central to its identity, and supporters of Bill 21 argue it is a reasonable step towards enshrining the separation of church and state in Quebec. Critics, however, argue that it discriminates against religious minorities, particularly Muslim women.
The notwithstanding clause allows a government to override certain fundamental freedoms of religion, expression, and association; as well as legal and equality rights, for a five-year term, after which it may be renewed indefinitely.
This week's hearing will mark the first time the Supreme Court has heard a challenge to the provision since 1988, indicating the case's critical role in shaping the future of civil liberties in Canada.
