McGill University is taking a proactive approach to making sure its students don’t offend anyone with their Halloween costumes.

Thursday, the Students’ Society of McGill University is holding its big 4Floors Halloween party — and organizers are vowing to turn anyone away with a costume it deems offensive.

CBC Daybreak reporter Shari Okeke spoke with student leaders Nicholas Szczerbickyj, Daniel Chaim and Claire Stewart-Kanigan about their firm approach to weeding out controversial costumes.

They explained that people working the door at the party will have a colour-coding system to approve — or reject — costumes. Green gets in, red gets turned away and yellow means they’re having trouble deciding, or that the person in costume doesn’t realize their get-up may be offensive.

That’s where it gets complicated. If student union vice-president Chaim and two other chairpeople can’t decide, they will consult two equity commissioners, meaning five opinions will come into play.
