Partenaires pour un Québec Français (PQF) said it wants the province’s language watchdog, the Office Québécois de la Langue Française (OQLF),to have more power and resources to protect French.
Mario Beaulieu, spokesman for the coalition, said Bill 101 was weakened to respect the presence of the "historic anglophone community."
"Gradually, with the weakening of Bill 101, we came back to full bilingualism. This means someone can live in English in Montreal without having to use French," said Beaulieu.
He added that with weak language laws, the province would not be able to force people to learn French.
Louise Mercier, spokeswoman for the Quebec Labour Federation, said encouraging new Quebeckers to speak French at work is crucial in fighting assimilation.
“One day, we will lose our language,” said Mercier.
Despite the concerns, Beaulieu said he is confident Montreal’s new Mayor Michael Applebaum understands the coalition’s mandate.
The PQF is a coalition comprised of some of the province’s largest unions, and traditional Quebec nationalist groups.
