SFU communications director Kurt Heinrich said the video appears to have been filmed inside the Maggie Benson Center.
Henrich told CTV News that the school investigated and "it appears that the raccoons did leave the building shortly after they finished with the trash."
"From time to time, community members will spot deer, raccoons and on rare occasions, even coyotes and bears -- though these animals usually keep away from the campus buildings," Heinrich said.
Students made light of the situation in the comments section of the post.
"At least they're recycling," Dave Coles wrote.
"They let anyone into SFU nowadays," Paul Sandhu joked.
