Quebec was set to consider emergency legislation Thursday aimed at calming weeks of student protests over rising tuition costs, after thousands took to the streets once again and more than 100 were arrested.

Authorities said 122 were arrested late Wednesday as thousands of demonstrators spilled into the streets of Montreal, with some smashing bank windows and hurling objects at police.

Legislation could be introduced as early as Thursday amid student strikes. Dozens of protesters on Wednesday stormed into one Montreal university for the first time, breaking up classes.

Premier Jean Charest said he would table emergency legislation aimed at ending the disorder, while sticking to the planned tuition hikes.

"It's time for calm to be restored," Charest said Wednesday. He added, "The current situation has lasted too long. ... Quebecers have a right to live in security."

Under the latest version of its tuition plan, the government would increase fees by $254 per year over seven years.
