Daily student demonstrations against a planned tuition increase are roiling Montreal, with a top official saying the protests are hurting the city, reports The Gazette. Michael Applebaum, chairman of Montreal’s executive committee, has warned that the demonstrations are damaging the city’s economy and raising safety concerns as police officers are diverted from their usual duties to monitor the more than 180,000 students estimated to be on strike from classes. The students, whose tuition is the lowest in Canada at $2,168 (Canadian), are protesting a tuition increase that by 2017 will raise the fee to $3,793. Their strike is open-ended, and colleges and universities in the province may have to extend their semester to make up for lost time.
