The PQ has not denied a leak to the media in August that detailed some of the proposals it wants to include in the charter, namely the banning of religious symbols such as hijabs, kippas, turbans and visible crucifixes for people who work with the public.
As a minority government, the PQ needs the support of some of its opponents to pass any legislation tied to the proposed charter.
But members of opposing parties have expressed deep concern about the language the PQ has used to explain the charter.
Premier Pauline Marois has been under fire ever since those details were leaked in August.
On the defensive, she has tried to explain why the charter’s aim at religious symbols in public institutions and the workplace was important to the PQ and to the province.
She told the French-language newspaper Le Devoir in an exclusive interview that people in England had turned to violence because the country lacked a sense of identity.
Marois also said women who wore hijabs and who worked in daycares could be in a position to incite children to practise religion.
Creating trouble, Liberal leader says
Provincial Liberal Leader Philippe Couillard said the PQ was purposely trying to create trouble in Quebec.
“It creates division and I’m afraid this is the objective here,” he told CBC News last week.
Federal Liberal Leader Justin Trudeau said Marois had “miscalculated her expectation of what Quebecers will respond to.”
NDP leader and Montreal MP Tom Mulcair said in August that he doubted the PQ could pull off a proposal such as this one.
At the time, he compared the proposed ban on religious symbols to Marois musing last year about requiring language tests for candidates in municipal elections.
"And I said, look, it's so patently unconstitutional they'll never do it. And guess what? It was so patently unconstitutional, they never did it," Mulcair said.
Details of the proposed charter of Quebec values will be reported after its unveiling at 10:45 a.m. ET.
