Dr. Annie Bunting, a social sciences professor and Africa expert at York University, poses for a photo in Toronto on Wednesday, June 20, 2018. Two of Dr. Bunting's Nigerian colleagues, a medical doctor and a scholar, were denied visitor visas to travel to Toronto to present their research which came at a time when the number of visa refusals in Canada has more than doubled since 2012.
