According to Montréal police, several windows at Concordia University were smashed and spray-painted earlier this week during a protest. The damage happened during what police called an “impromptu” protest involving a gathering of people who damaged windows at Concordia and other buildings downtown. CTV News reports that police arrested four people, who were released without charges. Concordia President Graham Carr issued a statement noting that the institution is assessing the events and will take appropriate actions in line with its Code of Rights and Responsibilities. Carr also called for respectful exchanges. “Whatever political or ideological differences exist between us, we have a larger collective responsibility to maintain a climate of respect […] and, ideally, to promote dialogue and curate the difficult conversations that will be needed to move us all forward,” said Carr.
