The protest was in response to planned budget cuts at the university, which has a $14 million shortfall.
The new budget, which was to be voted on Tuesday night, would see departments throughout the university facing a four per cent cut.
University president David Barnard told radio station CJOB that it's possible students won't see some courses offered next year.
He also said some jobs could be affected.
Michael Barkman, head of the Canadian Federation of Students, noted the provincial government increased post-secondary education funding by 2.5 per cent in the last provincial budget.
"We are concerned about these cuts, especially with a budget increase at a provincial level,” he said.
