Quebec's controversial secularism law, Bill 21, is set to face its most significant legal test as Canada's Supreme Court begins a four-day hearing in Ottawa on Monday. The 2019 law prohibits public sector workers in positions of authority—including judges, police officers, and teachers—from wearing religious symbols at work.

The case marks the first time Canada's highest court will rule on Bill 21, which has been upheld by lower courts through the use of the constitutional 'notwithstanding clause.' Thirteen challengers brought the case, including the Canadian Civil Liberties Association, the National Council of Canadian Muslims, the World Sikh Organization of Canada, and the English Montreal School Board.

What the Right Is Saying

Quebec Premier François Legault and supporters of Bill 21 argue the law upholds secularism and neutrality in public life—a concept known as laïcité in the majority French-speaking province. They insist the law is not intended to discriminate against any one religion.

After Bill 21 passed in 2019, Legault said: 'I think it's good for what we call the 'vivre ensemble',' using a French term for coexistence. The Quebec government, still under Legault's leadership, is now seeking to expand the secularism laws to include all staff at public schools beyond teachers and principals, as well as daycare centres, and to ban prayer in public spaces.

David Rand, president of a Montreal-based atheist group, said he believes the bulk of opposition to Bill 21 is coming from outside Quebec. He argues that 'religious convictions are no more sacred or untouchable than political convictions,' and that public displays of both should be cast aside by those working for the state.

Rand predicted a Supreme Court ruling that would force Quebec to scrap its secularism laws would be met with 'massive protest' in the province. Polls indicate a majority of Quebecers support Bill 21 and its expansions.

Elizabeth Elbourne, a historian at McGill University, said Quebec's Bill 21 reflects historical tensions over religion in the province. She noted the debate centers on whether Quebec sees itself 'as a multicultural society' or one that is more 'assimilationist.'

What the Left Is Saying

Progressive advocates and civil liberties groups argue Bill 21 discriminates against religious minorities and violates fundamental Charter rights. The National Council of Canadian Muslims and the Canadian Civil Liberties Association have led the constitutional challenge, arguing the law disproportionately targets Muslim women.

Nadia Hasan, a researcher and associate professor at York University in Toronto who has spoken to more than 400 Muslim women in Quebec about Bill 21, found that 73% felt the secularism law affected their ability to look for a job. A similar number said they have considered leaving the province, and more than half reported experiencing racist remarks or prejudice at work.

Lisa Robicheau, a 41-year-old Muslim woman who works as a contract support worker in Montreal's English-language school system, told the BBC she feels 'stuck between a rock and a hard place.' She said: 'I've spent the majority of my life here, but it never feels like home. I am constantly being treated like an outsider.'

Amrit Kaur, a Sikh teacher who grew up in Quebec and wore a turban, was one of the appellants in the case. In 2021, she wrote online that the law had 'shattered' her future as an educator in her home province, pushing her to flee 'religious persecution … like a refugee.' She now lives in British Columbia.

Hasan said she worries Bill 21 will continue to put a target on visible minorities, particularly Muslim women. Robicheau said she hopes the Supreme Court will set a national precedent 'that there are certain rights that are untouchable.'

What the Numbers Show

Bill 21 was passed in 2019 and applies to public sector workers in positions of authority, including judges, police officers, teachers, and principals. The law includes an exemption for those who were working before it was proposed.

Research by Professor Nadia Hasan at York University surveyed more than 400 Muslim women in Quebec: 73% said the law affected their ability to look for a job; 73% said they have considered leaving the province; and over 50% reported experiencing racist remarks or prejudice at work.

The law was upheld by lower Quebec courts because the province invoked the 'notwithstanding clause'—a constitutional provision allowing provinces to override certain Charter rights, including freedom of religion and equality rights. Dozens of Montreal school staff hired more recently have been fired or suspended, according to union leaders.

The Quebec government proposes expanding Bill 21 to cover all public school staff and daycare workers, and to ban prayer in public spaces. Polls indicate a majority of Quebec residents support these measures.

The Bottom Line

The Supreme Court hearing represents the most significant legal challenge to Bill 21 since its passage in 2019. The case is bigger than one law—it will also examine whether the notwithstanding clause can shield legislation that overrides fundamental Charter rights.

Whatever ruling the Supreme Court issues, the debate over secularism in Quebec is likely to continue. The law has already shaped the careers and lives of thousands of religious minority workers, particularly Muslim women who say they feel like outsiders in their own province. The case is being watched closely across Canada as a potential precedent for the limits of provincial power in overriding constitutional rights.
