Legault announced the proposal Monday and it comes as the debate over integrating new immigrants continues to simmer.
Legault says a third of the 50-thousand immigrants who arrive in Quebec every year don't speak French adequately, and four out of five don't meet the demands of the province's job market.
Legault wants the province to accept more trained professionals, and he thinks his language and culture requirements will help.
"We would like to put more emphasis in the first place on answering the working market needs," said Legault.
Immigrants who fail test would be kicked out
Under Legault's plan, new arrivals would have to take a test of their french-language skills and knowledge of Quebec values after three years.
If they don't pass after two tries, they'd be asked to return to their country of origin or go to another province.
Legault says a CAQ government would invest 80-million dollars a year to help immigrants succeed.
Parti Quebecois MNA MakaKoto calls the plan "improvised".
"How can you kick someone out of the country when it's the federal government that has power over visas?" Koto said.
Liberal immigration minister Kathleen Weil also criticized the plan.
She says it would drive potential immigrants to simply avoid Quebec in the future.Suggest a correction
