TORONTO 鈥 A proposal by Quebec to tax unvaccinated people may be lawful but may also go against the spirit of Canada鈥檚 universal public health system, rights and medical experts said on Wednesday.

Tuesday鈥檚 surprise announcement by the province鈥檚 premier, Francois Legault, came with few details.

While his government would not say Wednesday how the tax would be levied, when or against whom, Canada鈥檚 Civil Liberties Association said it could violate Canadians鈥 fundamental rights, while health advocates expressed concern about its broader implications.

鈥淚鈥檝e not seen anything like this in Canada before. I鈥檓 worried about the precedent it would set,鈥 said Danyaal Raza, a doctor with Unity Health in Toronto and former chair of Canadian Doctors for Medicare.

Quebec, Canada鈥檚 second-most populous province, is struggling with surging COVID-19 hospitalizations, and Mr. Legault noted that the province鈥檚 relatively small unvaccinated population was represented disproportionately among the hospitalized.

Facing a provincial election in October, his government鈥檚 response to the pandemic thus far has met with approval from 65% of Quebeckers surveyed, according to a Leger poll released this week.

But the province鈥檚 public health director stepped down earlier this week, prior to the tax plan announcement, citing an 鈥渆rosion鈥 of public trust in anti-pandemic measures.

Asked on Wednesday about the plan, Prime Minister Justin Trudeau said he 鈥渞eceived that proposal with interest鈥 but would not weigh in on it, saying he needed more details.

Canada鈥檚 public health system is underpinned by the Canada Health Act, meant to guarantee universality and accessibility, among other things. It precludes user fees for insured services.

Quebec鈥檚 tax could be framed as a 鈥渟in tax鈥 similar to that placed on alcohol and cigarettes or as a tax on a health risk factor like private insurers charge, Mr. Raza said.

As such, it might not violate Canada鈥檚 Health Act but that did not mean it was a good idea, he said.

Cara Zwibel, acting general counsel for the Canadian Civil Liberties Association, said it might however violate Canada鈥檚 Charter of Rights and Freedoms if viewed as 鈥渁 way of compelling people to get vaccinated.鈥

It was not clear if the tax鈥檚 goal is to convince more people to get vaccinated or to finance health care, she said.

McGill University biomedical ethicist Phoebe Friesen was concerned the logic of taxing unvaccinated people could be extrapolated to other behaviors seen as driving health spending 鈥 obesity, for example 鈥 but that are tied to marginalization.

鈥淚f you want to be consistent and logical, you should charge all sorts of people for their hospitalization if it鈥檚 based on behavior that they鈥檙e 鈥榬esponsible鈥 for,鈥 she said 鈥… And it鈥檚 incredibly tricky to figure out what that looks like.鈥 鈥 Reuters
