Students and government officials have resumed talks in Quebec City, aimed at ending a standoff over tuition fee hikes.
More than 80 protesters were arrested on Monday night, after gathering outside the building where negotiations are being held.
Students have been taking part in a mass strike for 16 weeks. They are angry over moves to increase fees by 75 per cent in the province.
At the moment, Quebec’s rates are the lowest in Canada – the equivalent of around 1,700 euros a year.
There have been nightly protests, in defiance of a new law that clamps down on demonstrations.
The government says it will not back down over the new fees.
