A closely watched constitutional battle over Quebec’s controversial secularism law, widely known as Bill 21, is set to unfold this week as the Supreme Court of Canada begins hearings on a case that could redefine the balance between legislative power and fundamental rights.
At the heart of the case is the province’s use of Section 33 of the Canadian Charter of Rights and Freedoms commonly referred to as the “notwithstanding clause.” This provision allows governments to override certain Charter protections, shielding laws from legal challenges related to fundamental freedoms.
Quebec’s government, led by Premier François Legault and his Coalition Avenir Québec party, invoked this clause pre-emptively when passing Bill 21 in 2019. The law enforces state secularism and bars public officials in positions of authority including teachers, police officers, and judges from wearing visible religious symbols while on duty.
While lower courts have largely upheld the legislation, they have also expressed unease over the breadth of Quebec’s use of the notwithstanding clause. Legal scholars say the Supreme Court’s ruling could have sweeping implications far beyond the province.
“This case is less about secularism itself and more about the limits of suspending fundamental rights,” said Louis-Philippe Lampron, a law professor at Université Laval. “Whatever the outcome, it will reshape constitutional interpretation in Canada.”
A central issue is whether governments can use Section 33 proactively before a law is even challenged to avoid judicial scrutiny. Critics argue that such use undermines the Charter’s purpose, while supporters insist it reflects parliamentary sovereignty.
The debate traces back to the landmark Ford v Quebec (1988) decision, in which the Supreme Court ruled that legislatures can invoke the notwithstanding clause without having to justify their actions. Courts in Quebec have followed that precedent while acknowledging concerns over its broad application.
In a 2021 ruling, Quebec Superior Court Justice Marc-André Blanchard described the province’s reliance on the clause as “excessive,” though legally permissible. The Quebec Court of Appeal later upheld most of that decision, reinforcing the law’s legal standing while warning that such use of Section 33 could weaken rights protections.
The case now presents the Supreme Court with several possible paths. It could reaffirm the Ford precedent, effectively granting Quebec a decisive victory. Alternatively, the court might rule that pre-emptive use of the notwithstanding clause is unconstitutional, sending the case back to lower courts for a full review under Section 1 of the Charter which requires governments to justify any limits on rights as reasonable in a free and democratic society.
Another potential outcome could see the court issue an advisory-style opinion on the law’s constitutionality, even if it has no immediate legal effect an approach recently suggested by Saskatchewan’s appellate court in a separate case.
Legal experts caution that the court cannot rewrite the Constitution, but its interpretation could significantly influence how Section 33 is applied in the future.
The Quebec government has already renewed Bill 21 once, extending its protection under the notwithstanding clause for another five years. With provincial elections approaching later this year, political accountability remains one of the few checks on its continued use.
However, critics argue that relying on elections offers little recourse for minority groups directly affected by the law.
As arguments begin, all eyes are on the country’s top court. The decision, expected later this year, is likely to leave a lasting mark on Canada’s constitutional landscape and on the ongoing tension between majority rule and minority rights.
